Enhancing The Conductivity Of PVDF Through Doping And Ion Implantation
Background and Goals
This technical report aims to enhance the conductivity of polyvinylidene fluoride (PVDF) through doping and ion implantation techniques. PVDF is a semi-crystalline polymer with excellent piezoelectric, pyroelectric, and ferroelectric properties, making it attractive for various applications, including sensors, actuators, and energy harvesting devices. However, its relatively low electrical conductivity limits its performance in certain applications.
Doping and ion implantation are promising approaches to improve the conductivity of PVDF. Doping involves introducing impurities or dopants into the polymer matrix, which can create charge carriers and enhance electrical conduction. Ion implantation, on the other hand, involves bombarding the polymer surface with high-energy ions, which can modify the material's properties and potentially increase its conductivity.
