通过碳微球在P34HB[聚(3-羟基丁酸酯/4-羟基丁酸酯)共聚物]发泡材料表面生长方式的研究,对发泡材料进行表面改性。碳微球是由石墨片层在玻璃相石墨结构中因间断分布而构成的,而P34HB具有无毒、可生物降解、易结晶和可热降解等特性。采用水热法合成碳微球,并以此作为P34HB发泡材料的表面改性剂。研究结果表明:碳微球经原位聚合后被乙烯基硅油包覆,并附着在P34HB发泡材料表面生长,使发泡材料表面呈疏水亲油状;碳微球对该发泡材料的表面改性效果良好,并且可使该发泡材料表面达到极佳的疏水亲油状态。
The surface modification of foamed material by carbon microspheres on the surface of P34HB [poly (3-hydroxybutyrate / 4-hydroxybutyrate)] foaming material was studied. Carbon microspheres are composed of graphene sheets dispersed in the glassy phase of glassy structure, while P34HB is non-toxic, biodegradable, easily crystallizable, and thermally degradable. Hydrothermal synthesis of carbon microspheres, and as P34HB foam surface modifier. The results showed that the microspheres were coated with vinyl silicone oil after in-situ polymerization and adhered to the surface of P34HB foaming material to make the surface of the foamed material hydrophobic hydrophobic lipophilic. The effect is good, and the surface of the foamed material can achieve excellent hydrophobic and lipophilic state.
