Barium titanate@ poly (methyl methacrylate) (BT@PMMA) nanocomposites were prepared via in situ atom transfer radical polymerization (ATRP). It was observed that the BT nanoparticles were coated with PMMA and excellently dispersed in the polymer matrix. Compared with the BT/PMMA nanocomposites prepared by the traditional solution blending, BT@PMMA nanocomposites show higher thermal conductivity and...
In this work, by using a hyperbranched aromatic polyamide grafted boron nitride nanoplatelets (BNNP-HBP), epoxy nanocomposites with high thermal conductivity and high breakdown strength are successfully prepared. All the composite samples with less than 40 wt% BNNP-HBP show increased thermal conductivity and breakdown strength when compared the pure epoxy resin and the composites with as received...
The development of devices for electric stress control includes several significant challenges for polymer composite dielectrics, including the need for high permittivity, high mechanical strength, high thermal conductivity, good dielectric strength, and good ductility. However, the conventional methods to increase the permittivity of a polymer suffer from very low mechanical and dielectric strength...
V.P.I. is the most advanced impregnation technology for the electrical machines that have been developed. With the rapid development of the electrical industry, demands of improving the properties of V.P.I. resins become higher and higher. It is of practical significance to investigate the effect of the modification of the epoxy resin TMPTMA on the cross-linking structure, the DC electrical resistivity...
We investigated the influence of the surface modification of Al nanoparticles on the electrical conduction of polyethylene composites. Octyl-trimethoxysilane was used as a coupling agent for the treatment of Al nanoparticle. It was found that the incorporation of octyl groups onto the surface of Al nanoparticle altered the time dependence behaviors of polarization and depolarization current and increased...
