摘要

基于考虑极性弹性体（PE）潜在分子物理的连续体理论，提出了一个典型的边值问题（BVP）来分析具有随机分布电介质颗粒的PE的机电不稳定性（EMI）。通过大量的数值模拟，研究了颗粒体积分数、颗粒尺寸和与极性基团相关的增强因子等各种参数对导致PE EMI的临界电压的影响。结果以三维相图的形式呈现，这可能有助于研究人员更好地理解PE的EMI，并指导他们在化学、物理、生物工程等领域合成、设计和应用PE。

On the Electromechanical Instability of Polar Elastomers

Based on a continuum theory that accounts for the underlying molecular physics of polar elastomers (PEs), a typical boundary value problem (BVP) is developed to analyze the electro-mechanical instability (EMI) of PEs with randomly distributed dielectric particles. Through extensive numerical simulations, the effects of various parameters such as particle volume fraction, particle size and enhancement factor related to polar groups on the critical voltage leading to EMI of PEs are investigated. The results are presented in 3D phase diagrams, which may better help researchers to understand EMI of PEs and guide them in synthesis, design, and application of PEs in the fields of chemistry, physics, bio-engineering, etc.
