Latest Patents

Matin’s patent, “Method of Cleaning a Fouled Reverse Osmosis Membrane,” describes a process for cleaning a fouled reverse osmosis membrane with a comb-shaped polymer. The method dissolves the polymer and a base in water, then applies the resulting solution to the membrane. The polymer includes reacted units of poly(isobutylene-alt-maleic anhydride) and an oligoethylene amine, such as triethylenetetramine, tetraethylene pentaamine, or pentaethylenehexamine.

His patent, “Method for Preparing a Superhydrophobic Self-Cleaning Surface,” concerns a substrate coated with a superhydrophobic layer formed from octadecyltrichlorosilane. The compound crosslinks to the substrate through surface hydroxyl groups. The described surface has a root-mean-square roughness of 40 to 60 nanometers, a water contact angle of 155° to 180°, and contact angle hysteresis below 15°.

The preparation method involves plasma-treating a substrate, hydroxylating it with water or alcohol, and applying an octadecyltrichlorosilane solution in an alkane solvent. The solution is dried under ambient air to form the self-cleaning surface.
