By measuring the electrical resistivity of RTV silicone rubber with Ni powder, the percolation threshold of Ni_based conductive silicone rubber was determined.
通过对镍粉填充rt V硅橡胶的电阻率的测量确定了镍基导电硅橡胶的渗滤值点。
The results showed that the composites exhibited percolation threshold effect obviously and the composites had preferable conductive property when carbon black content was 12%.
