Graphene as a novel additive in low density polyethylene (LDPE), high density polyethylene–low density polyethylene blend(10%HDPE–LDPE) and polypropylene–low density polyethylene blend (10%PP–LDPE), is investigated for promising ecofriendlyinsulating materials in high voltage cables. The composites with graphene amounts of 0, 0.002 wt%, 0.02 wt%,and 0.2 wt% are prepared by the solution mixing method. With attempt to disclose the structure–property relationships, thecomposites are extensively characterized by physical techniques including Fourier transform infrared spectroscopy, X-raydiffraction, atomic force microscopy, transmission electron microscopy, scanning electron microscopy, thermogravimetricanalysis and differential scanning calorimetry, and electrical measurements including electrical treeing, direct current conductivityand space charge distributions. Results show that graphene can significantly enhances the thermal stability of LDPEand 10%PP–LDPE, slightly decrease the degree of crystallinity, change the size of the crystal diameters, and improve thephase distribution of the polymer blends. Consequently, graphene can prolong the electrical tree initiation time and blockthe extension of electrical tree. Besides, it can modulate the trap distributions, which will further change the conductivityand ability to suppress space charge accumulations. This excellent performance of graphene could be attributed to its goodexfoliation, uniform dispersion and outstretched morphology in the polymer matrix, as well as its strong ability to captureelectrons.
