For a particular PS-PMMA block copolymer system, we found that effective compatibilization occurs at compatibilizer levels of 1-5 wt % in a 50/50 PS-PVC blend. In the samples, storage and stress relaxation moduli were at least midway between those of pure PS and PVC. On the other ...
就我分离ps-pmma block copolymer的经验来看,最好的溶剂是环己烷。环己烷在35度是polystyrene的西塔溶剂,用环己烷做溶剂对混合物进行脂肪萃取操作,一般能将它们分开。 3 评论0 举报 猫七姑娘,化工主管 2018-12-13回答 甲苯试试,估计ps分子量太高,甲苯也不好溶解,pmma是肯定不溶的 9 评论0 举报 哭、...
哪位同学对triblock copolymer中的poly(styrene- block -methylmethacrylate- block -styrene) 即PS-PMMA-PS; 或者poly(styrene-block-ethylene oxide-block-styrene)即PS-PEO-PS了解么? 看了文献想购买这两种材料,看到Polymer Source给的目录里面这两种材料有很多种不同配比,求问区别~ 我是学物理的,对化学方面完全...
The best strategies to transfer nanoholes formed from the self-assembly of Polystyren/Polymethylmethacrylate (PS/PMMA) based block copolymers into a silicon substrate are investigated. The authors show that specific issues are associated with the plasma etching of materials through the PS masks ...
