| Abstract: |
| By using liquid silicone rubber(LSiR) as matrix，nickel coated graphite(NCG) as electrically conductive filler， the NCG/LSiR composites were prepared，and the effects of addition levels of NCG，diluting agent toluene and coupling agent on the properties of the composites were investigated.The results showed that，when the addition level of NCG was 280 phr，the volume resistivity of the composite dropped to less than 0.1 Ω·cm.The properties of the composite prepared by using toluene as dilution solvent were unaffected，but the viscosity of the compound was reduced.Addition of coupling agent A187 could improve the adhesion of the composite to aluminum substrate，and the optimum addition level was 20 phr. |
