Flexible and low cost lead free composites with high dielectric constant
Source abstract
Abstract
Highly flexible lead free composite film having random distribution of ceramic filler was synthesized using Barium Titanate (BT) as a filler and inexpensive Thermoplastic Polyurethane (TPU) as a matrix. The results show that the 30 vol% BT-TPU composite has a dielectric constant of ~31 which is comparable to the expensive and difficult to produce PVDF based composites. With a breakdown field of 150 kV/mm, an energy density value of ~3 J/cm3 was estimated. These lead-free TPU based composites provide an alternative to PVDF based composites for energy storage applications.
