| 摘 要： | 以Ti (OC4H9)4 水解形成的溶胶体系为模板, 以AgNO3 为银纳米线的前驱体, 低温下合成长径比为50～60 的银纳米线, 采用TEM 和XRD 对所制得的银纳米线进行表征。以银纳米线作为导电胶的导电填料, 成功制备了一种高电导率的各向同性导电胶。导电胶的电学性能和力学性能测试表明: 这种导电胶在导电填料含量为56 wt %时的电导率比填充75 wt %微米银粒子的导电胶高约6 倍(体积电阻率为1. 2 ×10-4Ω·cm) 。由于填料含量的降低, 该导电胶的抗剪切强度(以Al 为基板时的抗剪切强度为17. 6 MPa) 相比于填充75 wt %微米银粒子和75 wt %纳米银粒子导电胶均有不同程度的提高。

| Abstract: | With the nanoporous templates formed by the cont rolled hydrolysis and condensation of butyl titanate( Ti (OC4H9)4 ) , silver (Ag) nanowires with a slenderness ratio of 50～60 were prepared by using silver nit rate (AgNO3 ) as precursor. The prepared Ag nanowires were characterized by X-ray diff raction (XRD) and t ransmissionelect ro microscopy ( TEM) . A new kind of isot ropical conductive adhesive ( ICA) was developed by using these Agnanowires as conductive filler. The bulk resistivity and shear st rength testing results show that the novel ICA filledwith Ag nanowires (mass f raction 56 %) has bulk resistivity (1. 2 ×10-4Ω·cm) 6 times lower than that of ICA filledwith Ag particles (mass f raction 75 %) . For the lower filler content , the ICA filled with Ag nanowires exhibit shigher shear st rength (17. 6 MPa on Al subst rate) than the ICA filled with micrometer-sized Ag particles or nanometer-sized Ag particles cloes. |
