摘要

为了推动电活性聚合物（DEAP）的发电产业化，本文根据电活性聚合物材料的电致大应变特性，分析了该材料的应力应变及本构模型。在此基础上，分析电活性聚合物的有效工作区域，揭示电活性聚合物在静电场中机电耦合及能量转换的内部机理，并研究了该材料的发电机理。最后，仿真研究了能量转换效率与应力应变的关系。根据能量循环过程，提出了恒电荷能量收集模型。采用丹佛斯生产的硅树脂超弹性材料，构建了DEAP发电实验平台，采用仿真及实验研究验证了电活性聚合物发电机理。仿真结果表明：电活性聚合物工作在应变为25%，激励电压为1.3 kV时，能到达最大的能量密度，约为5.8 mJ/cm3。实验结果表明：应变越大，收集能量越大，与理论分析越吻合.

Abstract

To promote the industrialization of Dielectric Electro Active Polymer (DEAP) Generator

the stress-strain and the constitutive model were analyzed respectively based on the large strain electroluminescence characteristics of DEAP materials.Then

allowable effective work-states were analyzed

the mechanisms of electromechanical coupling and energy transformation for the DEAP in a static electric field were explored and its generation mechanism was studied. Finally

the energy conversion efficiency and the relation between stress and strain for the DEAP were simulated and researched. According to the process of energy cycle

an energy collection model with constant charge was put forward. Furthermore， a generating platform was constructed on the silicon resin elastic material and the generating mechanism was verified by simulation and experiments. The simulation results indicate when the DEAP stress is 25% with a 1.3 kV charge voltage

modeled energy generated per cm3 of DEAP is almost 5.8 mJ/cm3. The experimental results show that the more strain is got

the more energy will be harvested from DEAP generator

meanwhile the experimental data will be more fitted the theoretical calculation.
