A comparative study of electrical aging of multiwalled carbon nanotubes and carbon black filled cross-linked polyethylene

In this work, XLPE/MWCNT and XLPE/CB nanocomposites have been prepared in order to investigate AC electric field and water effects on electrical aging of XLPE. The mechanical, AC breakdown strength and AC conductivity were tested and the morphologies after 30 days electrical aging were observed usin...
