摘　　要：以纳米石墨微片(NanoG)为导电填料,聚丙烯酸酯为基体,采用溶液共混法制备了纳米石墨微片/聚丙烯酸酯导电压敏胶。扫描电镜(SEM)显示纳米石墨微片直径为1～10μm,厚度为20～80nm。红外光谱测试(FTIR)表明纳米石墨微片与聚丙烯酸酯之间形成了氢键,两者形成了均相的复合体系。透射电镜(TEM)揭示了纳米石墨微片均匀地分散在导电胶中,并形成了导电网络;电性能测试表明当纳米石墨微片质量分数为40%时,复合物导电性能最佳,电导率达到1.28×10-2S/cm。导电压敏胶的剥离强度随着纳米石墨微片含量的增加逐渐下降,剪切强度先上升后下降。The electrically conductive pressure sensitive adhesive,comprising acrylate resin and graphite nanosheet（NanoG） as conductive filler,was prepared by solution blending method.The structures of NanoG and the electrically conductive pressure sensitive adhesive were characterized though scanning electron microscopy（SEM）,fourier transmission infrared（FTIR） and transmission electron microscope（TEM）.Results show that the NanoG had a diameter ranging 1-10μm and thickness ranging 20-80nm and homogeneously dispersed in forming conducting network in the electrically conductive pressure sensitive adhesive.The FTIR reveals that the hydrogen bonding was formed between pure acrylate resin and NanoG.The electrical conductivity of the electrically conductive pressure sensitive adhesive increased to 1.28×10-2 S/cm when the content of the conductive filler was 40%.The 180° peel strength of the electrically conductive pressure sensitive adhesive decreased gradually with the filler content increased.While the shear strength increased when the content of the filler increased from 0% to 20%.
