在超临界CO2中进行了苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)与马来酸酐(MAH)的接枝反应,用扫描电子显微镜对接枝共聚物进行了表征。结果表明,控制适当的接枝率,可以分别得到具有皱折型和乳突型的微/纳米表面粗糙结构的接枝共聚物。
The grafting reaction of styrene - butadiene - styrene block copolymer (SBS) with maleic anhydride (MAH) was carried out in supercritical CO2. The graft copolymer was characterized by scanning electron microscopy. The results show that grafting and mastoid type micro / nano surface roughness grafted copolymers can be obtained by controlling the appropriate grafting ratio.
