| 摘 要： | 采用聚氨酯增韧环氧树脂,并利用有机化的纳米SiO2为改性剂制备纳米改性环氧树脂胶黏剂.利用扫描电子显微镜( SEM)观察无机纳米粒子在聚合物基体中的分散性及复合材料的断面形貌,结果表明无机纳米粒子在复合材料中分散性良好,而且聚氨酯在环氧树脂基体中形成了“孔洞结构”.采用电子拉力机、TGA以及介电谱仪等方法测试了复合材料...

| Abstract: | Organic precursor of EP/PU was prepared by epoxy resin which was polyurethane toughened,and then modified epoxy resin adhesive was synthesized using nano-silica as modifier.Microstructure of composite materials was observed by scanning electron microscopy(SEM).The results showed that the inorganic phase had well dispersed in the polymer matrix,and the polyurethane has formed the hole structure in the epoxy resin substrate.The mechanical properties,thermal stability and dielectric loss,dielectric constant of... |
