丙烯酸酯/镍/聚苯胺导电复合压敏胶的制备及其电容传感性能
Fabrication and capacitive sensing performance of acrylate/nickel/polyaniline conductive composite pressure-sensitive adhesive
摘要
Abstract
In this study,the conductive pressure-sensitive adhesive was prepared through multiple solution casting.Chain spherical nickel powders(C-Ni),flake nickel powders(F-Ni)and polyaniline(PANI)were incorporated as functional fillers into the resultant acrylic type pressure-sensitive adhesive(a-PSA).The results indicated that these fillers were asymmetrically distributed in the thickness direction of the conductive pressure-sensitive adhesive due to the effect of grav-ity.This significantly improved the electrical properties of the resultant composite pressure-sensitive adhesive.The a-PSA/10 wt％C-Ni/1 wt％PANI composite adhesive exhibited the highest conductivity of 0.013 S/m.With increasing the PANI content,there was an increase in the response of the capacitance to bending angle and pressure of the compos-ite adhesives.The most sensitive response to bending angle was observed for the composite adhesives containing 1 wt％PANI.At a pressure of 12.5 kPa,the change rate of capacitance of the composite adhesive reached 1.83.Its tensile strength was 2.88 times as much as that of the a-PSA,whereas its adhesion strength decreased with an increase in the filler content.The a-PSA/10 wt％C-Ni/1 wt％PANI composite adhesive exhibited the best comprehensive perfor-mance.关键词
