摘要/Abstract

摘要： 将碳纳米管(CNTs)和乙酸银同时引入到环氧树脂-咪唑固化体系中, 在固化过程中原位热降解银-咪唑复合物生成纳米银修饰碳纳米管, 差示扫描量热仪(DSC)表明改性碳纳米管对环氧固化有一定的促进作用. 采用X-射线衍射(XRD)表征了乙酸银和咪唑配合物[Ag(2E4MZ)₂]Ac 的结构, 并提出了原位降解生成纳米银的机理. XRD结果表明, 单独的乙酸银-咪唑配合物热降解生成的纳米银粒径为21-24 nm, 而配合物在环氧基体中生成的纳米银粒径为11-13 nm. 添加80%(质量分数)片状微米银粉制备的纳米银/碳纳米管环氧导电复合材料其体积电阻率低达9×10^-5 Ω·cm. 当纳米银和碳纳米管质量比为80:20 时, 复合材料导电性和剪切强度达到最佳; 采用扫描电镜(SEM)表征了复合材料的形貌结构.

Abstract: Nanosilver-decorated carbon nanotubes (CNTs) were prepared by introducing CNTs and silver acetate into an epoxy-imidazole curing system and simultaneous in situ thermal degradation of an Ag-imidazole complex. Differential scanning calorimetry (DSC) results indicated that modified CNTs played a certain role in promoting the curing of the epoxy. The structure of the silver acetate-imidazole complex was characterized by X-ray diffraction (XRD). The size of the nano-silver particles resulting from degradation of the Ag-imidzole complex was between 21 and 24 nm, and between 11 and 13 nm when the Ag-imidzole complex was added to the epoxy matrix. When silver flakes with a mass fraction of 80% was added to the composites, the volume resistivity of the nanosilver-decorated CNTs/epoxy conductive composite was as low as 9×10^-5 Ω·cm. The optimum conductivity and shear strength were achieved when the ratio of nanosilver and CNTs was 80:20 (mass ratio). Scanning electron microscopy (SEM) revealed the structural morphology of the composite.
