Abstract:
1. An elastomer-conductive filler composite comprising a matrix consisting of an elastomer, conductive fillers dispersed in the elastomer matrix, and an ionic liquid, wherein the conductive fillers are dispersed in the elastomer matrix by a dispersing agent consisting of the ionic liquid, wherein the ionic liquid comprises a di, tri and tetraalkylimidazolium cation and at least one anion selected from the group consisting of B(CN) 4 , CH 2 CHBF 3 , CF 3 BF 3 , C 2 F 5 BF 3 , nC 3 H 7 BF 3 , nC 4 H 9 BF 3 , PF 6 , CF 3 CO 2 , N(SO 2 CF 3 ) 2 , N(COCF 3 )(SO 2 CF 3 ), N(SO 2 F) 2 , N(CN) 2 , C(CN) 3 , SCN, SeCN, CuCl 2 , AlCl 4 , Al 2 Cl 7 , and OH, and wherein the ionic liquid is present in the composite in an amount of more than 1 part by weight and less than 10 parts by weight, based on 1 part by weight of the conductive fillers.
