摘要
The effect of crosslinking degree on the piezoresistive behavior of carbon black(CB) filled poly(methyl vinyl siloxane)(PMVS) vulcanites under uniaxial compression was studied.The results reveal that increasing the amount of crosslinking agent could weaken the negative pressure coefficient of resistance(NPCR) effect at the late stage of compression and enhance the piezoresistivity intensity at a high stresses.The recovery property of resistance was related to the content of CB,the stress level and the degree of crosslinking.It was proved that repeated compression with the same maximum stress level could improve piezoresistive stability considerably.
