Description
本実施形態に係る感圧導電性エラストマーは、非導電性エラストマー中に、板状、針状、又は繊維状の導電性フィラーと、粒径がナノメーターサイズのセラミック粒子とを分散させたものである。
非導電性エラストマーとしては、1液型の常温硬化シリコーンゴム(信越化学工業株式会社製,KE−445)を用いた。導電性フィラーとしては、板状の導電性セラミック粉末(大塚化学株式会社製,BK400M,サイズ:3〜8μm,平均アスペクト比:2.7)を用いた。セラミック粒子としては、ヘキサデシルアミンをインターカレートしたモンモリロナイト粉末(クニミネ工業株式会社製,クニピアF,平均2次粒子径:5μm)を用いた。
導電性フィラーとしてカーボンブラック粒子(日本カーボン株式会社製,粒径:1〜10μm,平均粒径:5μm)を用い、セラミック粒子の代わりにシリコーンゴム粒子(東レダウコウニング株式会社製,粒径:20〜120μm,平均粒径:70μm)を用いた他は、実施例と同様の操作を行った。その結果を図3、図4、及び表2に示す。なお、耐久特性については、繰り返し回数を4000回と17000回とした。
導電性フィラーとして針状の導電性セラミック粉末(大塚化学株式会社製,BK400W,サイズ(長さ):10〜20μm,平均アスペクト比:43)を用い、セラミック粒子を添加しない他は、実施例と同様にして繰り返し(2〜10回)の圧縮変形に対する電気抵抗値変化特性(F−R特性)を調べた。その結果を図5及び表2に示す。
