Combining good dispersion with tailored charge trapping in nanodielectrics by hybrid functionalization of silica

e-Polymers, 2021
Fumed silica-filled polypropylene (PP)-based nanodielectrics were studied in this work. To not only improve the dispersion of the silica but also introduce deep charge traps into the polymeric matrix, five types of modified silicas were manufactured with
