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;表面接触角
The grafting reaction of styrene-butadiene-styrene block copolymer (SBS) with maleic anhydride was carried out. When the graft ratio was controlled at 11.5%, the graft polymerization of micro-nano surface roughness The surface contact angle of SBS graft copolymer decreased obviously.
