摘要
在乙烯基甲基硅橡胶（ＶＭＱ－１１０）中加入自制的纳米乙炔导电纤维（Ｎａｎｏ），可制备出性能良好的导电橡胶。实验表明，在ＶＭＱ－１１０中加入ｌ０～３５份Ｎａｎｏ，其混炼胶的导电性能接近导电乙炔炭黑混炼胶，且混炼胶柔软，加工性好；当Ｎａｎｏ用量大于３０份时，硫化胶的Ｐｓ小于１０３Ω，加入５０份ｐｖ降至１０Ω·ｃｍ；随着Ｎａｎｏ用量增加，硫化胶的硬度、拉伸强度都增加，扯断伸长率呈线性下降。
The conductive and physical properties of vinyl methyl silicone rubber(VMQ-110) vulcanizates filled with a novel nanometer conductive fiber(Nano) were observed as well as its micro-structure and morphology of filled distribution in silicone vulcanizates by TEM techniques.The experimental results presented that the conductive properties of Nano in silicone were similar to those of acetylene-conductive carbon black, and filled with 30% mass of Nano,the silicone became a conductive rubber.When filled with 50% mass of Nano,the volume resistivity decreased to 10Ω.cm,giving rise a very good reinforcing effect and higher resilience to the silicone vulcanizates.
