Description

Technical field [0001] The present invention involves a four -arm star -shaped polymer honeycomb -shaped porous film and preparation method. Background technique [0002] The water drop template method is a method of preparation of orderly micro -structural materials in recent years.The prepared honeycomb -shaped multi -porous membranes have very important application prospects in micro -containers and microcarulaers, optical materials, cell culture stents, ultra -hydrophobic surfaces, pattern templates, biomedicine and other fields.At present, the most common film formation substance is a polystyrene and a cluster obtained by the agglomeration of the anion.Actual application.The development of activity free radical aggregation makes the structure and chain length control of the film formation material possible, so that it is more advantageous in maintaining the morphological structure of honeycomb -shaped ordered film, providing good opportunities for the development of water dr...
