Evaluation of Peel Strength of a Polyaniline/Acrylic Anti-Static Pressure-Sensitive Adhesive

Pressure-sensitive adhesives (PSAs) are protected using a release liner, which when peeled off from the PSA, causesstatic electricity generation, damaging circuits in semiconductor wafers. Therefore, preparation of anti-static PSAsused in various industries, such as electronic, telecommunication, aerospace, and medical equipment, is of crucialimportance. In this research, an acrylic PSA was synthesized and solution blended with ۵ and ۰۱ wt. % ofpolyaniline (PANI) with respect to the PSA total solid content. The electrical conductivity of the PSA free of PANIand containing ۵ and ۰۱ wt. % of PANI was ۸.۴×۰۱-۷, ۰.۱×۰۱-۶, and ۰.۷×۰۱-۶ S/cm at ۰۱۵ Hz, respectively. Theglass transition temperature of all of the PSAs was about ۴۸ °C lower than their application temperature, indicatingtheir suitable flowability on the substrate. With an increase in the PANI content, the peel force enhanced inaccordance with an increase in the high-frequency storage modulus, leading to the higher viscoelastic dissipationof the PSAs during debonding.
