[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 662,350, filed on June 20, 2024, which is incorporated herein by reference in its entirety.

[0004] FIELD OF THE INVENTION

[0005]

[0002] This application relates to integration of ceramic materials with cellulose-containing substrates, which provides improved mechanical properties and resistance to biological fouling when the substrates are exposed to water.

[0006] BACKGROUND

[0007]

[0158]

[0145] Several cellulosic polymer substrates were used as polymer substrates for the deposition of ceramic. These include a sample of a cellulose (paper) faced gypsum board, oriented strand board (OSB), and a cellulose facer paper. A fiberglass mat that could be used for a glass faced gypsum board was included as a control. Of note, fiberglass mat and OSB both had a hydrophobic surface before any treatment was performed.

[0159]

[0146] A first solution containing zinc sulfate (400mM) and potassium persulfate (75mM) in DI water was prepared. Ammonium hydroxide was added and stirred until the first solution formed a homogeneous opaque white gel (approximately 1-2 minutes) Samples were then fully submerged in the solution. After 30 minutes in solution, the samples were removed from the deposit and rinsed in DI water by dipping until excess gel and particulate stopped coming off. The samples were then dried in a forced convection oven at 105°C for 60 min. After drying, samples were then functionalized (top coated) with hexadecyltriethoxysilane containing top coat from a suspension with a concentration of about 1 g / L suspension in isopropanol Samples were submerged in the top coat solution for about 90 minutes and then removed without rinsing, and were dried in a forced convection oven for about 75 minutes at about 140°C.

[0215]

[0185] A 500|im thick polyurethane film was applied to the aluminum substrate by placing the film on the substrate and placing a hot iron on the paper backing of the film for about 30 seconds. The paper was then peeled off and the film was observed to partially penetrate the pores and left a visual residue on the top of the sample surface. The resulting sessile droplet contact angle of the sample was unchanged from the virgin film. Alternatively, the polyurethane film was applied by placing the substrate in the oven at 200°C with a film and a stainless steel weight to press the film down. Again, the film was observed to partially penetrate the porous structure but left a significant amount of the film above the structured layer and no change to the sessile droplet contact angle was observed, indicating a loss of the underlying structure due to the film thickness.

[0219]

[0188] A cellulosic paper is used as polymer substrates for the formation of polymer-ceramic composites, as shown schematically in Fig. 3. In one embodiment, a roll 11 of cellulosic paper 12 can be passed into processing equipment 21 and a ceramic deposited, thereby making a cellulosic paper ceramic composite 29. In another embodiment, the paper ceramic composite 29 is passed to a drying section 43. In another embodiment, the dried paper ceramic composite is aligned with a second roll 41 of a polymer film 42 and adhered or laminated 49. The polymer film 42 can provide one or more functional benefit, such as water repellency, oil repellency, vapor barrier properties, color, environmental protection, and / or adhesive transfer In some embodiments, additional processing or curing equipment 51 is used to generate the final laminated composite material 59. In some embodiments, the second roll 41 is a polymer film including polyurethane, acrylic, LCP, polyolefins, meltblown films or meltblown nonwoven material having desirable properties In some embodiments, a liquid solution or slurry 32 is contacted with the cellulosic paper ceramic composite 29 with thickness controlled by a weir, blade, or other means 33 and is dried 43. The processing steps of 31-39 may alternatively be an immersion process 35 with a nip roller 36 for dewatering, a gravure coater 37, or a spray coater 38. In other non-limiting embodiments, the formation of a paper ceramic composite 29 is achieved in the processing steps 21-29 by any of the methods described in the previous examples and the paper ceramic composite 29 is subsequently processed by several additional non-limiting methods 31-59 In some embodiments, paper ceramic composites 29 are formed with polymeric feature dimensions of about 5 to about 500 urn and characteristic ceramic feature dimensions of about 0.2 to about 20 urn.

For the noted characteristic dimensions, this corresponds to film thicknesses of about 0.5 urn to about 100 urn. In some embodiments, the film 42 may be a large open structure nonwoven material having a density less than 20 g / m2that is melted in downstream curing equipment 58.

[0220]

[0189] In some embodiments, paper ceramic composites 29 are formed with polymeric feature dimensions of about 5 to about 500 urn and characteristic ceramic feature dimensions of about 0 2 to about 20 urn. In some embodiments, the paper ceramic composites 29 having characteristic polymeric feature dimensions of about 5 urn to about 500 urn and characteristic ceramic feature dimensions of about 0.2 urn to about 20 urn are contacted with a film 42 having characteristic thickness of less than about 20% of the polymeric feature dimensions or less than about 500% of the ceramic dimensions. For the noted characteristic dimensions, this corresponds to film thicknesses of about 0.5 urn to about 100 urn. In some embodiments, the film 42 may be a large open structure nonwoven material having a density less than 25 g / m2or about 10% of the bulk substrate that is melted in downstream curing equipment 58. Applied films having the characteristics noted above demonstrate an increase in sessile drop contact angle over the virgin film (as measured according to ISO 19403), demonstrating at least a partial pattern or roughness transfer.

The gypsum boards were tested for bond strength between the gypsum core and the polymer ceramic composite by peeling the ceramic polymer composite away from the gypsum core while measuring the force required to peel the sections apart during elongation. The Peel strengths and Cobb ratings are normalized to the bare sample. The results of the Cobb test and peel testing results are shown in Table 4.
