| 摘 要： | 采用熔体共混法制备了笼型硅氧烷齐聚物(POSS)/硅橡胶复合材料.利用X射线衍射仪和电子显微镜对复合材料中的POSS分散情况进行了观察,结果表明,熔体共混后,一部分POSS以分子水平分散在硅橡胶中,另一部分POSS则由于自组织结晶以微米颗粒分散在硅橡胶中.采用橡胶加工分析仪对复合材料的加工性能进行了表征,结果表明,某些情况下POSS对硅橡胶产生了增塑效应.POSS对硅橡胶的增强效应、增塑效应取决于其分散结构.

| Abstract: | The polyhedral oligomeric silsesquioxane/silicone rubber composite was prepared by melt blending method through Haake inner mixer.The dispersion of POSS in rubber matrix was characterized by X-ray diffractometer and electron scanning microscope.The results showed that part of POSS might disperse in rubber in molecule level after mixing,while another part existed in matrix in crystal particles owing to the crystallization of POSS molecules through self-assembly.Rubber Processing Analyzer(RPA2000)was employed to evaluate the processing performance of composite.It was found that in some cases,POSS produced the plasticizing effect on rubber.The reinforcement of plasticizing effect or POSS was dependent on its dispersion structure. |
