| 摘 要： | 以聚丁二醇丁二酸酯（PBS）为基材,经-甲基丙烯酰氧基丙基三甲氧基硅烷偶联剂（KH570）改性过的纳米SiO2和未改性的SiO2为填料,采用熔融共混法制备了PBS/SiO2纳米复合材料。研究了所得纳米复合材料的热稳定性能、力学性能和降解性能等。结果表明：当经KH570表面改性的纳米SiO2（KH570与纳米SiO2的质量之比为1：5）的添加质量分数为4%时,复合材料的维卡软化点约提高了10℃,拉伸强度约提高30%,同时复合材料的降解性能比PBS纯料的降解性能有一定的提高。

| Abstract: | PBS was blended in a twin-screw extruder with unmodified nanoscale SiO2 and nanoscale SiO2 modified with KH570 to provide PBS/SiO2 nanocomposite.The heat resistance,mechanical properties and degradation of PBS/SiO2 nanocomposite were studied.The results showed that when PBS blended with nanoscale SiO2 modified with KH570（m（coupling agent）：m（nano-SiO2）=20%） by 4wt%,the vicat softening point of PBS/SiO2 nanocomposite increased by about 10℃,tensiles properties increased about 30%.Meanwhile,the degradation of PBS/SiO2 nanocomposite increased to certain degree than pure PBS. |
