Abstract

Journal of Thermoplastic Composite Materials, Ahead of Print.
This study investigates how carbon black (CB) distribution in co-continuous polypropylene (PP)/poly(ethylene-co-vinyl acetate) (EVA) blends affects electrical impedance spectroscopy (EIS) properties. PP:CB and EVA:CB masterbatches with 1, 2, or 3 vol% CB ...
