Special Issue Information

Dear Colleagues,

Polymer-based dielectric gels represent a burgeoning area of research due to their unique combination of flexibility, dielectric properties, and adaptability in various technological applications. These materials are characterized by their polymer matrix, which is embedded with dielectric constituents, leading to exceptional properties such as high permittivity, low dielectric loss, and excellent mechanical flexibility. The increasing demand for advanced materials in electronic devices, sensors, and energy storage systems underscores the significance of exploring and understanding these innovative gels.

This Special Issue, entitled “Polymer-Based Dielectric Gels”, aims to provide a comprehensive platform for researchers and industry experts to present their latest findings and developments in the field of polymer-based dielectric gels. The primary objective is to elucidate the fundamental aspects, synthesis methods, and potential applications of these materials. Topics of interest include, but are not limited to, the following: novel methods for synthesizing polymer-based dielectric gels; strategies for designing and optimizing polymer matrices and dielectric fillers to enhance performance characteristics; innovative applications of polymer-based dielectric gels in various fields; and computational studies and theoretical models to predict the behavior of polymer-based dielectric gels.

Potential authors are encouraged to contribute original research articles, comprehensive reviews, and insightful perspectives that will collectively advance the understanding and application of polymer-based dielectric gels. Through this Special Issue, we aim to highlight the transformative potential of these materials and inspire innovative solutions to contemporary technological challenges.

Silicone gel, used in the packaging of high-voltage, high-power semiconductor devices, generates bubbles during the packaging process, which accelerates the degradation of its insulation properties. This paper establishes a testing platform for electrical treeing in silicone gel under pulsed electric fields, investigating the effect of pulse voltage amplitude on bubble development and studying the initiation and growth of electrical treeing in a silicone gel with different pulse edge times. The relationship between bubbles and electrical treeing in silicone gel materials is discussed. A two-dimensional plasma simulation model for bubble discharge in silicone gel under pulsed electric fields is developed, analyzing the internal electric field distortion caused by the response times of different ions and electrons. Additionally, the discharge current and its effects on silicone gel under pulsed electric fields are examined. By studying the influence of different pulse edge times, repetition frequencies, and temperatures on discharge current magnitude and ozone generation rates, the impact of electrical breakdown and chemical corrosion on the degradation of organic silicone gel under various operating conditions is analyzed. This study explores the macroscopic and microscopic mechanisms of dielectric performance degradation in organic silicone gel under pulsed electric fields, providing a basis for research on high-performance packaging materials and the development of high-voltage, high-power semiconductor devices.
