•Curing temperature has higher correlation in electrical conductivity.•MVQ/CPP composite cured at 205 °C shows higher conductive.•Network structure of composite varied because of curing temperature.•Relationship between network structure and conductivity variation was discussed.•Variation of mechanical properties of composite was slight.
In this paper, conductive silicone rubbers filled with carbonyl permalloy powder (CPP) have been prepared at different curing temperatures. The volume resistivity, crosslink density, tensile strength, elongation at break, Shore A hardness and morphology structure have been investigated. The results indicated that the correlation between electrical conductivity and curing temperature was significant. Volume resistivity of the composite decreased about four orders of magnitude in the range of curing temperature from 125 °C to 225 °C, which was related to the changes of crosslink density, but the change on mechanical properties was relatively small.
