This work concerns the study of electrical properties of polymer nanocomposite materials. Through the addition of nanoparticles in a polymer matrix, we seek to improve the physical properties of these “innovative” materials. We propose to study the influence of incorporating silica nanoparticles in a HDPE matrix on the accumulation of space charge. The results presented in this article shall be given...
This work presents some electrical characterisation performed on nanocomposite materials. These compounds were obtained by the dispersion of inorganic nanoparticles into a matrix of High and Low Density Polyethylene (PE). The nanocomposites have been prepared by melt compounding using a twin screw extruder. The dielectric breakdown strength of the nanocomposites was investigated using AC progressive-stress...
Polypropylene is extensively used as a dielectric in power capacitors, electrical machines and transformers. It has excellent mechanical, thermal, and electrical properties and provides outstanding resistance to moisture, grease, and oils. It does not present stress-cracking problems and at high temperatures it offers better thermal and chemical resistance than polyethylene. A thermoplastic such as...
