摘要
研究镀银镍粉体积分数对镀银镍粉/硅橡胶高导电复合材料性能的影响。结果表明:随着镀银镍粉体积分数增大,复合材料的邵尔A型硬度增大,拉断伸长率快速减小,体积电阻率减小并出现明显逾渗现象;当镀银镍粉体积分数为0.44时,复合材料具有良好的导电稳定性和优异的电磁屏蔽效能,但耐电化学腐蚀性能较差。
The effect of the volume fraction of silver-coated nickel powder on the properties of silvercoated nickel powder/silicone rubber high conductive composite was investigated. The results showed that,with the increase of the volume fraction of silver-coated nickel powder,the Shore A hardness of the composite increased,the elongation at break decreased rapidly,the volume resistivity decreased and obvious percolation occured. When the volume fraction of silver-coated nickel powder was 0. 44,the composite had good conductivity stability and excellent electromagnetic shielding effectiveness,but the electrochemical corrosion resistance was poor.
