摘要

以正硅酸乙酯( TEOS) ，甲基丙烯酸甲酯(MMA) 为主要原料，甲基丙烯酸-β-羟丙酯为活性单体，溶胶-凝胶法制备PMMA/SiO

杂化准凝胶，并以其为填充物对PP 进行复合改性。采用FT-IR、XRD、SEM 、PLM 等对材料的结构进行分析，同时对其力学性能进行测试，研究了复合材料力学性能与组成、结构间的关系。研究发现，PMMA/SiO

杂化材料能诱导PP 基体中β 晶型的生成，并使PP 球晶细化。PP/SiO

杂化复合材料( PSH) 中 SiO

含量为2 %(wt) 时，缺口冲击强度较纯PP 提高81 %。

Abstract

Tetraethoxysilane ( TEOS)

methyl methacrylate ( MMA) and 2-hydroxy propyl methacrylate ( HPMA) were used to prepare SiO

/PMMA hybrid quasi-gels by sol-gel method .The hybrid quasi-gels were used to modify PP as filler .FT-IR 、XRD 、SEM and PLM were employed to study the structure of PP/SiO

hybrid nanocomposites and the relationships among property

structure and composition of these composites were studied at the same time .The results show that PMMA/SiO

hybrid quasi-gel can induce PP to form β crystal and minimize the spherulite size in PP .When the content of SiO

in PP/SiO

hybrid nanocomposite ( PSH) is 2 %( wt)

the toughness strength is increased by 81 % than pure PP .
