Developing Novel Self Healable Capacitor Materials with Improved Thermostability

The current work reports the chemical modification of polyolefins in presence of a free radical initiator via reactive extrusion. The crosslinked network is formed upon radical coupling during processing which is substantiated by viscoelastic measurements. The network formed consists of a polyethylene gel with free polypropylene with improved dielectric properties. The designed material is stable at elevated temperatures with an inherent self-healability which renders it a potential candidate as capacitor in power electronics.
