| 摘 要： | 采用气相法先将聚甲基丙烯酸甲酯(PMMA)引入纳米介孔分子筛MCM-41的一维孔道内,制备出PM-MA/MCM-41复合粒子,再与环氧树脂(EP)共混,研究了PMMA/MCM-41复合粒子对EP/(PMMA/MCM-41)复合材料拉伸性能的影响。结果表明,PMMA分子链引入到MCM-41的孔道内,并且孔口处的PMMA与EP产生了较强的界面相互作用,增加了两者的相容性。PMMA/MCM-41复合粒子使EP的拉伸强度、拉伸弹性模量、断裂伸长率均有所提高。

| Abstract: | Epoxy resin/(PMMA/MCM-41) nanocomposite was prepared by solution blending after encapsulation of PMMA within the channels of MCM-41.The effect of PMMA/MCM-41 on the tensile properties of the composite was investigated.The results showed that PMMA was entrapped in the pores of MCM-41.Encapsulation of PMMA into the pores of MCM-41 could improve the compatibility between the matrix and MCM-41 because the PMMA at the ends of the pores of PMMA/MCM-41 could interact with epoxy matrix.The tensile strength,elastic modulus intension and breaking elongation were raised efficiently by adding PMMA/MCM-41. |
