想碳化非溶剂诱导相分离聚丙烯腈膜,在氧化前处理过程中发黑变脆?280度预氧化,温度偏高了。220-240即可,脆的问题不好解决, 我看“A hierarchical porous carbon membrane from polyacrylonitrile/polyvinylpyrrolidone blending membranes: Preparation, characterization and electrochemical capacitive performance”和“Hierarchically Porous Carbon Membranes Derived from PAN and Their Selective Adsorption of Organic Dyes”这两篇文献都是烧制并碳化非溶剂诱导相分离的膜,而且后者还用于过滤染料。请问为什么他们的膜韧性尚可,而我的一碰就碎了呢?查看更多
