[0055] In step 1) of the preparation method according to the present invention, a certain amount of carboxylated carbon nanotubes is first added to the nano-template particle dispersion with a mass fraction of 6w / v% to 15w / v%, and the ultrasonic treatment is configured to 1 mg / v mL to 20mg / mL carbon nanotube dispersion, in this process, carbon nanotubes and nano template particles are fully mixed.
[0056] Preferably, in step 1), the nano-template particles can be selected from SiO 2 , polystyrene beads, ZnO and Au metal nanoparticles, nanosheets and at least one of nanorods.
[0057] The nanotube in the present invention is a one-dimensional nanomaterial with light weight, perfect connection of hexagonal structure, and many abnormal mechanical, electrical and chemical properties. The carbon nanotubes mainly consist of carbon atoms arranged in a hexagon to form a coaxial circular tube with several to tens of layers. A fixed distance is maintained between the layers, about 0....

[0082] Example 1: Preparation of carbon nanotube porous microspheres with compact surface
[0083] (1) Add a certain amount of carboxylated carbon nanotubes to the 2 In the dispersion of nanoparticles (with a particle size of 200nm), ultrasonic treatment was used to configure a 7.5 mg / mL carbon nanotube dispersion as the water phase, and hexadecane containing 30 wt% of the surfactant Span 80 as the oil phase.
[0084] (2) The above-mentioned two-phase fluid is introduced into a polydimethylsiloxane (PDMS) flow-focused microfluidic chip through a fluid pump to prepare monodisperse droplets. Since the droplets are wrapped with a certain concentration of SiO 2 nanoparticles and carbon nanotubes, due to SiO 2 The electrostatic repulsion between nanoparticles and the reduction of droplet surface free energy make SiO 2 Nanoparticles and carbon nanotubes are closely arranged on the surface of the micron droplet, the flow rate ratio of the dispersion liquid and the oil phase is 1:5,...
Embodiment 2
[0089] This embodiment is basically the same as Embodiment 1, except that: in this embodiment, a PDMS chip is used as a microfluidic chip. image 3 It is a schematic diagram of the droplet generated by the glass chip in this embodiment.
