Abstract
Description
technical field
[0001] The invention relates to a photosensitive random copolymer honeycomb porous film and a preparation method. Background technique
[0002] Since the French scientist Francois et al. found that an ordered porous structure was formed on the surface of the polymer film when the polystyrene star polymer or the carbon disulfide solution of the block polymer was dropped on a solid substrate to prepare a film, the water droplet template based on solvent volatilization This method has become an attractive method for preparing ordered microstructured materials. The prepared honeycomb ordered membrane has the advantages of uniform pore size distribution and highly ordered pore arrangement. It has very important application prospects. At present, the most common film-forming substances are polystyrene and its copolymers obtained by anionic polymerization, but the conditions of anionic polymerization are harsh and the applicable monomers are less, and the product ...
