Joint Project Proposal on: Development, Development, Characterization, and Applications of Cellular Fluoropolymer Films with Ferroelectret Properties Subproject on: Electrical Preparation and Investigation of Cellular Fluoropolymer Films

在这个子项目中，将研究和优化新型蜂窝含氟聚合物驻极体薄膜的充电和电荷捕获行为，以获得高压电响应和良好的热稳定性和时间稳定性。为此，将开发和改进埃尔兰根大学提供的适用于蜂窝含氟聚合物的充电和调理工艺。研究的工艺参数包括加料场、温度、时间、气体环境和压力。此外，通过表面和体电荷测量、热诱导和光诱导放电实验、不同非细胞和细胞聚合物和样品的比较以及模型计算，将研究非细胞和细胞氟聚合物驻极体的潜在电荷存储现象。

In this subproject, the charging and charge-trapping behavior of novel cellular fluoropolymer electret films will be investigated and optimized with respect to high piezoelectric response and good thermal and temporal stability. To this end, suitable charging and conditioning processes for the cellular fluoropolymers provided by the University of Erlangen will be developed and refined. Among the process parameters to be studied are the charging field, temperature, time, gas environment and pressure. Furthermore, the underlying chargestorage phenomena will be investigated an non-cellular and cellular fluoropolymer electrets by means of surface and bulk charge measurements, thermally and optically induced discharge experiments, comparison of different non-cellular and cellular polymers and Samples as well as model calculations.
