Latest Patents

Zhou's latest patents reflect his deep understanding of material science and engineering. The first patent focuses on a coating material for aluminum substrates used in inkjet computer-to-plate applications. The composition consists of a high polymer (5-40 wt %), nano-sized and/or micro-sized oxide particles (5-30 wt %), and an organic solvent making up the remainder. The high polymer selection includes MMA-BMA-MA terpolymer resin, phenolic resin, epoxy resin, polyurethane, polyester, urea-formaldehyde resin, polyvinyl formal, polyvinyl butyral, and gum arabic. The preparation method involves mixing the ingredients and stirring them at room temperature, followed by coating the aluminum substrate using spin or roll coating methods, ultimately aiming for optimal surface roughness through baking.

The second patent introduces an ink specifically designed for direct inkjet printing to plates, based on nanometer materials. This ink consists of 5 to 30 wt % film-forming resin, 0.01 to 5 wt % nanometer or micrometer dye, 30 to 60 wt % organic solvent, and the remainder primarily water. The preparation method requires stirring the ingredients at room temperature, followed by multi-level filtering to remove impurities. This innovative ink allows for printing patterns on metal surfaces that can achieve a press run of up to 100,000 copies with a high resolution of 175 lpi, significantly reducing chemical pollution and post-processing efforts.
