A method comprising forming a coating solution which comprises a matrix precursor material, a porogen material and a solvent, by selecting a polyarylene matrix precursor material which cross-links to form a matrix with a calculated cross-link moeity density of at least 0.003 moles/ml, and reacting the polyarylene matrix precursor material with a porogen which is linear oligomer or polymer which is formed from monomers comprising alkenyl or alkynyl functional monomers, which has reactive end groups and a weight average molecular weight in the range of less than about 5000, where the porogen is present in amounts in the range of about 10 to less than 50 percent by weight based on total weight of porogens and matrix precursor material.
一种方法,包括通过选择交联密度至少为0.003摩尔/毫升的聚芳烃基质前体材料,与一种孔形成剂材料和溶剂组成涂层溶液,将聚芳烃基质前体材料与一种孔形成剂反应。孔形成剂是由含有烯基或炔基官能单体的单体形成的线性寡聚体或聚合物,具有反应性末端基团和重量平均分子量小于约5000的范围,其中孔形成剂的含量在孔形成剂和基质前体材料的总重量基础上为约10至小于50重量百分比。
