Abstract: The present invention relates to a cross-linked porous membrane from hydrolysis of ester-containing side chain and a preparation method thereof. Firstly, membrane material is obtained through copolymerization of four monomers including butyl methacrylate, styrene, sodium sulfonated styrene and vinylbenzyl chloride. In membrane formation, a small amount of lithium chloride micromolecule porogen is added and cross-linked by using tetramethyl hexamethylene diamine to prepare a nanoscale dense membrane through hydrolysis under the alkaline condition. Through the characteristic of hydrolysis of a butyl ester side chain in the polymer under the alkaline condition, the space originally occupied by the butyl ester in the hydrolyzed membrane is vacated; and after hydrolysis, with the appearance of carboxylic acid ionic conduction groups, a large quantity of ester bonds is hydrolyzed, so that the patency of ion transfer channels in the membrane is enhanced. Thus, ionic conductivity of the membrane is greatly enhanced.

Abstract: A method of modifying the wetting properties of the surface of a substrate, the method comprising the step of applying a first mold having an imprint forming surface to said substrate to form a first imprint thereon, said imprint forming surface being chosen to modify the wetting properties of the substrate surface.

Abstract: A method for forming hierarchical patterns on an article by nanoimprinting is disclosed. The method includes using a first mold to form a primary pattern on the article at a first temperature and a first pressure, the first temperature and the first pressure being able to reduce the elastic modulus of the article; and using a second mold to form a second pattern on the primary pattern at a second temperature that is below the article's glass transition temperature, the forming of the second pattern being at a second pressure.
