摘要/Abstract

摘要： 采用种子乳液聚合方法制备了聚（丙烯酸正丁酯/甲基丙烯酸甲酯-co-甲基丙烯酸缩水甘油酯）核壳增韧剂（PBMG），并用湿法球磨与超声辅助相结合的方法对六方氮化硼（h-BN）进行改性，制备的改性氮化硼（MBN）可提高环氧树脂（EP）的热导率。最后采用机械共混方法制备了环氧树脂/增韧剂/改性氮化硼（EP/PBMG/MBN）复合材料。通过透射电子显微镜（TEM）、扫描电子显微镜（SEM）、X射线衍射（XRD）、动态激光光散射（DLS）、热导率和力学性能等测试对核壳增韧剂的粒子形成、改性氮化硼和复合材料进行了表征。结果发现：最终制备的聚丙烯酸酯乳胶粒子呈现明显的核壳结构，且粒度分布很窄。当聚丙烯酸酯增韧剂添加量为5%、改性氮化硼为8.99%时，环氧树脂/增韧剂/改性氮化硼复合材料的冲击强度和热导率比纯环氧树脂（EP）的分别提高了133%和171%。随着未来的基板材料要求有效的热耗散，这种复合材料有望用于微电子工业上。

Abstract: A toughening modifier, poly(n-butyl acrylate)/poly(methyl methacrylate-co-glycidyl methacrylate), PBMG, core-shell structured latex was synthesized via seed emulsion polymerization. Hexagonal boron nitride (h-BN) was modified by wet ball milling combined with sonication to improve the thermal conductivity of epoxy resin (EP), donated as MBN. Then, EP/PBMG/MBN composites were prepared by mechanical mixing. The particle formation of PBMG, MBN and EP/PBMG/MBN composites were characterized by transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray diffraction (XRD), dynamic laser scattering (DLS), thermal conductivity and mechanical testing. These measurements showed that the PBMG particle obviously presented a core/shell structure and a narrow size distribution. The unnotched impact strength and the thermal conductivity of the EP/PBMG/MBN composite increased by 133% and 171% compared with those of pure epoxy resin, respectively, when the contents of PBMG and MBN components were 5% and 8.99%. These composites may offer new applications in the microelectronic industry because future substrate materials require effective heat dissipation.

Key words: epoxy resin, core/shell structure, hexagonal boron nitride, toughening, thermal conductivity
