在超临界二氧化碳中制备具有微/纳米表面结构的苯乙烯-丁二烯-苯乙烯嵌段共聚物接枝马来酸酐(英文)

Preparation of styrene-butadiene-styrene block copolymer grafting maleic anhydride with micro-nano surface structure in supercritical carbon dioxide

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 micro-nano surface structure of solid is very useful for the preparation of micro-nano template, and super-hydrophobic surface, etc. This paper describes a method for the preparation of micro-nano surface structure of solid by using grafting reaction of block copolymer in supercritical CO2.
