[0006] The porous metal oxide spheres or photonic balls can be prepared using a polymer sacrificial template. In one embodiment, an aqueous colloidal dispersion containing polymer particles and a metal oxide is prepared, where the polymer particles are typically nanoscale. The aqueous colloidal dispersion can be mixed with a continuous oil phase, for example in a microfluidic device, to produce a water-in-oil emulsion. The emulsion droplets are prepared, collected and dried to form spheres (typically microscale) containing the polymer particles and the metal oxide. The polymer particles (spheres) are then removed, for example by calcination, to obtain spherical metal oxide particles (spheres) containing high porosity and typically nanoscale pores. The spheres can contain uniform pore sizes, which is a result of the polymer particles being spherical and monodisperse.
[0007] Figure 1 shows a general overview of the preparation of the present porous microspheres. The emulsion droplets containing the polymer nanospheres and metal oxide are dried to remove the solvent to provide structured microspheres containing the polymer nanospheres with the metal oxide in the interstitial spaces between the polymer nanospheres (template microspheres or "direct structure"). The polymer nanospheres define the interstitial spaces. Calcination results in the removal of the polymer and provides the present metal oxide microspheres with high porosity or void volume (inverse structure).
[0008] The porous metal oxide spheres are advantageously sintered to produce a continuous solid structure that is thermally and mechanically stable.
[0009] In some embodiments, droplet formation and collection occurs in a microfluidic device. A microfluidic device is a narrow channel device with a droplet junction on the micron scale suitable for generating droplets of uniform size, for example connected to a collection reservoir. The microfluidic device contains a droplet junction with a channel width of, for example, about 10 μm to about 100 μm. The device is made of, for example, polydimethylsiloxane (PDMS) and can be prepared, for example, by soft lithography. An emulsion can be prepared in the device by pumping an aqueous dispersed phase and an oil continuous phase at a specific speed into the device, where mixing occurs, to obtain emulsion droplets. Alternatively, an oil-in-water emulsion can be utilized.
[0010] In some embodiments, vibrating nozzle techniques can be used. In these techniques, a liquid dispersion is prepared, droplets are formed and dropped into a bath of a continuous phase. The droplets are then dried, followed by removal of the polymer. Vibrating nozzle instruments are available from Buchi, and include, for example, a syringe pump and a pulsation unit. The vibrating nozzle instrument can also include a pressure control valve.
[0011] The polymer particles have, for example, an average diameter of about 50 nm to about 999 nm and are monodisperse.
[0012] Suitable template polymers for the spheres include thermoplastic polymers, for example, the template polymer is selected from the group consisting of poly(meth)acrylic acid, poly(meth)acrylate, polystyrene, polyacrylamide, polyvinyl alcohol, polyvinyl acetate, polyester, polyurethane, polyethylene, polypropylene, polylactic acid, polyacrylonitrile, polyvinyl ether, derivatives thereof, salts thereof, copolymers thereof, and combinations thereof. For example, the polymer is selected from the group consisting of polymethyl methacrylate, polyethyl methacrylate, poly(n-butyl methacrylate), polystyrene, poly(chloro-styrene), poly(alpha-methylstyrene), poly(N-methylolacrylamide), styrene / methyl methacrylate copolymer, polyalkylated acrylates, polyhydroxyl acrylates, polyaminoacrylates, polycyanoacrylates, polyfluorinated acrylates, poly(N-methylolacrylamide), polyacrylic acid, polymethacrylic acid, methyl methacrylate / ethyl acrylate / acrylic acid copolymer, styrene / methyl methacrylate / acrylic acid copolymer, polyvinyl acetate, polyvinylpyrrolidone, polyvinylcaprolactone, polyvinylcaprolactam, derivatives thereof, salts thereof, and combinations thereof.
[0013] In certain embodiments, the polymeric template includes polystyrenes, including polystyrene and polystyrene copolymers, including copolymers with water-soluble monomers, such as polystyrene / acrylic acid, polystyrene / poly(ethylene glycol) methacrylate, and polystyrene / styrene sulfonate.
[0014] The metal oxides include transition metal, semi-metal and rare earth oxides, such as silica, titania, alumina, zirconia, ceria, iron oxide, zinc oxide, indium oxide, tin oxide, chromium oxide, mixed metal oxides, combinations thereof, etc. Metal oxides selected from the group consisting of silica, titania, alumina and combinations thereof are preferred.
[0015] The wt / wt (weight / weight) ratio of polymer particles to metal oxide is, for example, from 0.1 / 1 to 10.0 / 1 or from 0.5 / 1 to 10.0 / 1.
[0016] The continuous oil phase may include, for example, organic solvents, silicone oils or fluorine oils. According to the present invention, "oil" means an organic phase that is immiscible with water. Organic solvents include hydrocarbons such as heptane, hexane, toluene, xylene, etc., and alkanols such as methanol, ethanol, propanol, etc.
[0017] The emulsion droplets are collected and dried to remove the polymer, for example by microwave irradiation, in a heated oven, under vacuum, in the presence of a desiccant, or a combination thereof.
[0018] Polymer removal can be accomplished, for example, by calcination, pyrolysis, or with a solvent (solvent stripping). Calcination, in some embodiments, is carried out at a temperature of at least about 200° C., at least about 500° C., at least about 1000° C., from about 200° C. to about 1200° C., or from about 200° C. to about 700° C. Calcination can be for a suitable period of time, such as from about 0.1 hours to about 12 hours, or from about 1 hour to about 8.0 hours. In other embodiments, calcination can be for at least about 0.1 hours, at least about 1 hour, at least about 5 hours, or at least about 10 hours.
[0019] Alternatively, a liquid dispersion containing polymeric nanoparticles and a metal oxide is formed with an oil dispersed phase and a continuous water phase to form an oil-in-water emulsion. The oil droplets can be collected and dried in the same way as water droplets.
[0020] Alternatively, a liquid dispersion of polymer particles (e.g., nanoparticles) and metal oxide is prepared and spray-dried to form polymer template spheres (e.g., spherules) without forming a liquid-in-liquid emulsion. In certain embodiments of the spray-drying technique, a liquid solution or dispersion is fed (e.g., pumped) into an atomizing nozzle with a compressed gas inlet. The feed is pumped through the atomizing nozzle to form droplets. The droplets are surrounded by preheated gas in an evaporation chamber, resulting in evaporation of the solvent to produce solid particles. The dried particles are carried by the drying gas through a cyclone and deposited in a collection chamber. The gas includes nitrogen and / or air. In one embodiment of the present spray-drying method, the liquid feed contains a water or oil phase, polymer particles, and a metal oxide. In one embodiment of the present spray-drying method, the liquid feed contains a water or oil phase, polymer particles, and optionally a metal oxide. Polymer template spheres are provided that contain polymer spheres with a metal oxide in the intermediate space between the polymer spheres. The polymer spheres define the intermediate space. Spray-drying techniques include inkjet spray-drying methods and devices.
[0021] In this spray drying technique, air can be considered as the continuous phase (liquid-in-gas emulsion) with a dispersed liquid phase. In certain embodiments, the spray drying comprises an inlet temperature of about 100°C, about 105°C, about 110°C, about 115°C, about 120°C, about 130°C, about 140°C, about 150°C, about 160°C, or about 170°C to about 180°C, about 190°C, about 200°C, about 210°C, about 215°C, or about 220°C. In some embodiments, pumping rates (feed flow rates) of about 1 mL / min, about 2 mL / min, about 5 mL / min, about 6 mL / min, about 8 mL / min, about 10 mL / min, about 12 mL / min, about 14 mL / min, or about 16 mL / min to about 18 mL / min, about 20 mL / min, about 22 mL / min, about 24 mL / min, about 26 mL / min, about 28 mL / min, or about 30 mL / min are utilized. Spray drying techniques are disclosed, for example, in US2016 / 0170091.
[0022] FIG. 4 is a representation of a spray drying process according to some embodiments of the present invention.
[0023] The spheres are spherical or sphere-like, and in certain embodiments are micron-scale, e.g., having an average diameter of about 0.5 microns (μm) to about 100 μm. The polymer particles utilized as templates are also spherical, and in certain embodiments are nano-scale and monodisperse, e.g., having an average diameter of about 50 nm to about 999 nm. The metal oxide utilized may also be in particulate form, and the particles may be nano-scale.
[0024] The metal oxide of the dispersion may be provided as the metal oxide or may be provided from a metal oxide precursor, for example by sol-gel techniques.
[0025] Drying of the polymer / metal oxide droplets, followed by removal of the polymer, provides spheres with uniform voids (pores). Typically, in this method, each droplet provides a single sphere. The pore size depends on the size of the polymer particle. Some "shrinkage" or compaction occurs during polymer removal, and the size of the pores may be somewhat smaller than the original polymer particle size, for example, about 10% to about 40% smaller than the polymer particle size. The pore size is uniform, as is the shape and size of the polymer particles.
[0026] The pore size, in some embodiments, may range from about 50 nm to about 999 nm.
[0027] The average porosity of the metal oxide spheres can be relatively high. The average porosity of a sphere refers to the total pore volume as a fraction of the total volume of the sphere. The average porosity is sometimes referred to as the "volume fraction."
[0028] In some embodiments, the porous sphere can have a solid core (center) and the porosity is generally to the exterior surface of the sphere. In other embodiments, the porous sphere can have a hollow core and the majority of the porosity is to the interior of the sphere. In other embodiments, the porosity can be distributed throughout the volume of the sphere. In other embodiments, the porosity can exist as a gradient, with more porosity towards the exterior surface of the sphere and less or no porosity towards the center (solid), or less porosity towards the exterior surface of the sphere and more or complete porosity towards the center (hollow).
[0029] For any porous sphere, the average sphere diameter is preferably greater than the average pore size, for example, the average sphere diameter is at least about 25 times, at least about 30 times, at least about 35 times, or at least about 40 times greater than the average pore size.
[0030] In some embodiments, the ratio of the average sphere size to the average pore size is, for example, about 40 / 1, about 50 / 1, about 60 / 1, about 70 / 1, about 80 / 1, about 90 / 1, about 100 / 1, about 110 / 1, about 120 / 1, about 130 / 1, about 140 / 1, about 150 / 1, about 160 / 1, about 170 / 1, about 180 / 1, or about 190 / 1 to about 200 / 1, about 210 / 1, about 220 / 1, about 230 / 1, about 240 / 1, about 250 / 1, about 260 / 1, about 270 / 1, about 280 / 1, about 290 / 1, about 300 / 1, about 310 / 1, about 320 / 1, about 330 / 1, about 340 / 1, or about 350 / 1.
[0031] Polymer template spheres, including monodisperse polymer spheres, can provide metal oxide spheres having pores with generally similar pore sizes when the polymer is removed.
[0032] The average diameter of the spheres (eg, microspheres) may be from 0.5 μm to 100 μm, or from 1 μm to 75 μm, or from 4.5 μm to 9.9 μm.
[0033] The average porosity of the spheres (eg, spherules) may be from 0.10 to 0.90, or from 0.10 to 0.80, or from 0.45 to 0.65.
[0034] The average pore size of the spheres (eg, microspheres) may be from 50 nm to 999 nm, from 50 nm to 800 nm, and from 220 nm to 300 nm.
[0035] Certain embodiments are directed to porous microspheres, the microspheres having an average diameter of 0.5 μm to 100 μm, an average porosity of 0.10 to 0.90 or 0.10 to 0.80, and an average pore size of 50 nm to 999 nm.
[0036] Other embodiments are directed to porous metal oxide spheres having an average diameter of 1 μm to 75 μm, an average porosity of 0.45 to 0.65, and an average pore size of 50 nm to 800 nm.
[0037] A further embodiment is directed to porous metal oxide spheres having an average diameter of 4.5 μm to 9.9 μm, an average porosity of 0.45 to 0.65, and an average pore size of 220 nm to 300 nm.
[0038] Without wishing to be bound by theory, it is believed that bulk samples of spheres will exhibit absorption if the porosity and / or sphere diameter and / or pore size are within certain ranges.
[0039] The porous spheres may primarily comprise metal oxide, i.e., they may consist essentially of or consist of metal oxide. The amount of metal oxide in the spheres may be, for example, 50 to 99.9% by weight based on the weight of the sphere. Certain embodiments have a lower limit of 60%, or 70%, or 90%, or 95% by weight.
[0040] Advantageously, the porous spheres (eg, microspheres) may also be monodisperse.
[0041] According to the present invention, particle size is synonymous with particle diameter, and is determined, for example, by scanning electron microscopy (SEM) or transmission electron microscopy (TEM). Average particle size is synonymous with D50, meaning that half of the population is above this point and half is below. Particle size refers to primary particles. Particle size can be measured by laser light scattering techniques using dispersions or dry powders.
[0042] Mercury porosimetry analysis was used to characterize the porosity of the microspheres. Mercury porosimetry applies a controlled pressure to a sample submerged in mercury. An external pressure is applied to the mercury, which penetrates into the voids / pores of the material. The amount of pressure required to penetrate into the voids / pores is inversely proportional to the size of the voids / pores. Mercury porosimetry generates a volume and pore size distribution from the pressure vs. penetration data generated by the instrument using the Washburn equation. For example, porous silica microspheres containing voids / pores with an average size of 165 nm have an average porosity of 0.8.
[0043] The term "bulk sample" refers to a population of spheres. For example, a bulk sample of microspheres is simply a bulk population of microspheres, e.g., ≧0.1 mg, ≧0.2 mg, ≧0.3 mg, ≧0.4 mg, ≧0.5 mg, ≧0.7 mg, ≧1.0 mg, ≧2.5 mg, ≧5.0 mg, ≧10.0 mg, or ≧25.0 mg. A bulk sample of spheres may be essentially free of other components. The terms "porous spheres" or "porous microspheres" may refer to a bulk sample.
[0044] The term "of" can mean "comprises," for example, "a liquid dispersion of" can be interpreted as "a liquid dispersion comprising."
[0045] The terms "microspheres," "nanospheres," "droplets," and the like, as referred to herein, can refer to, for example, a plurality thereof, a collection thereof, a population thereof, a sample thereof, or a bulk sample thereof.
[0046] The term "micro" or "microscale" means from about 0.5 μm to about 999 μm. The term "nano" or "nanoscale" means from about 1 nm to about 999 nm.
[0047] The terms "sphere" and "particle" may be interchangeable.
[0048] The term "monodisperse" in reference to a population of spheres or spheres means particles having a generally uniform shape and a generally uniform diameter. A monodisperse population of the present microspheres or nanospheres can have, for example, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, or 99% of the particles having a diameter within ±7%, ±6%, ±5%, ±4%, ±3%, ±2%, or ±1% of the average diameter of the population.
[0049] Removal of the monodisperse population of polymer spheres provides porous metal oxide spheres having a corresponding population of pores having an average pore size.
[0050] The term "essentially free of other components" means, for example, containing ≦5% by weight, ≦4% by weight, ≦3% by weight, ≦2% by weight, ≦1% by weight, or ≦0.5% by weight of other components.
[0051] The articles "a" and "an" herein refer to one or more than one (e.g., at least one) of the grammatical object. Any ranges cited herein are inclusive. The term "about" used throughout is used to describe and account for small variations. For example, "about" can mean a numerical value that can be modified by ±5%, ±4%, ±3%, ±2%, ±1%, ±0.5%, ±0.4%, ±0.3%, ±0.2%, ±0.1%, or ±0.05%. A numerical value modified by the term "about" includes the particular specified value. For example, "about 5.0" includes 5.0.
[0052] All parts and percentages are by weight unless otherwise noted. Weight percent (wt%) is of the total composition unless otherwise noted.

[0248] The UV measurements for application examples 1 to 19 are carried out as follows: Ultraviolet transmission spectra were measured using a Varian 5000 UV-Vis-NIR dual beam spectrophotometer. The plaque to be measured was placed in a sample holder and the transmitted light was measured by the receiver between 200 and 800 nm in 1 nm increments. No reference beam was used. A 0% transmission reference was determined by blocking the measurement beam to the receiver. A 100% transmission reference was determined by allowing the measurement beam to reach the receiver unobstructed.
[0249] [Synthesis Example 1] Porous Silica Microspheres Styrene / acrylic acid copolymer was prepared as follows: 230 mL of deionized (DI) water is added to a three-necked reaction flask equipped with a thermometer, condenser, magnetic stirring, and nitrogen atmosphere. The water is heated to 80° C. and 10 g of styrene is added with stirring, followed by 100 mg of acrylic acid dissolved in 10 mL DI water via syringe. 100 mg of ammonium persulfate is dissolved in 10 mL DI water and added to the stirred mixture via syringe. The reaction mixture is stirred at 80° C. for 24 hours. The polymer colloidal dispersion is cooled to room temperature and purified by centrifugation to produce polystyrene nanospheres with an average particle size of 250 nm.
[0250] The aqueous polystyrene colloidal dispersion is diluted to 1 wt% with deionized water, 1 wt% silica nanoparticles are added, and the mixture is sonicated to prevent particle aggregation. The continuous oil phase contains 0.1 wt% polyethylene glycol / perfluoropolyether surfactant in fluorinated oil. The aqueous colloidal dispersion and oil are each injected by a syringe with a pump into a microfluidic device with a 50 μm drop junction. The system is allowed to equilibrate until monodisperse droplets are produced. The monodisperse droplets are collected in a reservoir.
[0251] The collected droplets are dried in an oven at 45° C. for 4 hours to obtain monodisperse polymer templated microspheres. The polymer templated microspheres are placed on a silicon wafer and calcined by heating from room temperature to 500° C. over 3 hours, holding at 500° C. for 2 hours, and recooling to room temperature over 3 hours. Monodisperse silica microspheres with an average diameter of 15 microns are obtained.

[0253] [Synthesis Example 2] Drying method Repeating Example 1, the drying step utilizes microwave irradiation, drying under vacuum, and / or drying in the presence of a desiccant.
[0254] [Synthesis Example 3] Preparation of porous silica microspheres by spray drying. Styrene / acrylic acid copolymer was prepared as follows: 230 mL of deionized (DI) water is added to a three-necked reaction flask equipped with a thermometer, condenser, magnetic stirring, and nitrogen atmosphere. The water is heated to 80° C. and 10 g of styrene is added with stirring, followed by 100 mg of acrylic acid dissolved in 10 mL DI water, added via syringe. 100 mg of ammonium persulfate is dissolved in 10 mL DI water and added via syringe to the stirred mixture. The reaction mixture is stirred at 80° C. for 24 hours. The polymer colloidal dispersion is cooled to room temperature and purified by centrifugation to produce polystyrene nanospheres with an average particle size of 250 nm.
[0255] An aqueous polystyrene colloidal dispersion is diluted to 1 wt% with deionized water, 1 wt% silica nanoparticles are added, and the mixture is sonicated to prevent particle aggregation. The aqueous dispersion is spray-dried to obtain polymer-templated microspheres containing polymer nanospheres and silica. The microspheres are calcined by heating from room temperature to 500°C for 3 hours, holding at 500°C for 2 hours, and recooling to room temperature for 3 hours. Porous silica microspheres are obtained.
[0256] [Synthesis Example 4] Zinc oxide porous spheres A sample of porous zinc oxide microspheres was prepared according to the procedure of Example 3, substituting zinc oxide for silica, and the polystyrene nanospheres have an average particle size of 230 nm and a wt / wt ratio of polymer to zinc oxide of 1:2. A 0.5 mg sample of the porous microspheres was placed in a 6 cm 2 The sample appears a distinct blue color to the human eye.
