Parametric Study of EAPap Material Properties

摘要

Cellulose paper is used as base material for so-called electroactive papers (EAPap) actuator. EAPap is a complex anisotropic material, which has not been extensively characterized and additional basic testing is required before developing application devices from EAPap. Mechanical properties of EAPap were investigated in this work under different environmental conditions (humidity, temperature, and electrical field) and configurations. It shows viscoelastic effect and exhibits two distinct elastic and plastic modulus connected by a bifurcation point. Through tests, environment and configuration effects on EAPap are obtained to researchers and designers interested in the field of smart materials and EAP.
