溶胀接枝法制备具有微-纳米表面结构的苯乙烯-丁二烯-苯乙烯接枝共聚物(英文)

Preparation of styrene-butadiene-styrene graft copolymer with micro-nano surface structure by swelling graft polymerization

中对苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)与马来酸酐进行了溶胀接枝反应,当接枝率控制在11.5%时可以获得微-纳米表面粗糙结构的接枝聚合物,水在SBS接枝共聚物的表面接触角明显减小。关键词:苯乙烯-丁二烯-苯乙烯嵌段共聚物;溶胀接枝法;微-纳米表面结构;

The wettability of solid surface is a very important property for practical applications, and it depends on the surface energy and geometrical structure of the solid surface. This paper described a method for the preparation of micro-nano surface structure by using grafting reaction of block copolymer.
