“…However, the complicated and energy consuming production process as well as unavoidable environmental problems associated with thermosetting characteristics of XLPE, have limited further development of XLPE cables. The by‐products during crosslinking process which reported to cause space charge formation in the bulk XLPE is also another major obstacle for the application of XLPE in HVDC cables . Recently, polypropylene (PP) based TPEs attracted many researchers attention due to their potential to replace XLPE as DC cable insulation .…”

Thermoplastic elastomer (TPE) has gained acceptance as third generation of polymeric materials for high voltage (HV) insulators. The interesting features showed by TPEs were found to fulfill some particular requirements for HV insulations, at least for the distribution class applications, especially at light contamination environments. Introduction of nanomaterials which widely reported to give significant improvements in the electrical, mechanical, thermal and other properties of polymer has attracted attention to the synergistic properties of combining the two complementary technologies of thermoplastic elastomers and nanocomposites. In this paper, research works on various types of TPEs having promising performance as HV insulators are thoroughly reviewed. The emergence of nanocomposites in the electrical insulation field and the important properties consideration for HV insulators as well as the processing techniques of TPE nanocomposites are also discussed. Finally, some of the past and recent developments of TPE nanocomposites focusing on the electrical insulation properties are highlighted in this article. POLYM. ENG.

“…However, sample B0 has higher dielectric constant and dielectric loss value than other composites. Du et al found that the dielectric constant of inorganic nanocomposite is lower than neat polymer even the dielectric constant of fillers is higher than polymer matrix . The explanation is that the movement of molecular chain is restricted due to the interaction between polymer chain and nanoparticles and the entanglements of polymer chain which restricts polymer polarization.…”

[44][45][46] The explanation is that the movement of molecular chain is restricted due to the interaction between polymer chain and nanoparticles and the entanglements of polymer chain which restricts polymer polarization. In sample B0, the interfacial adhesion is weak resulting in formation of gaps or voids introduced in interfacial region.…”

The polypropylene‐g‐polystyrene (PP‐g‐PS) copolymers with different grafting ratios are used as compatibilizers to control the size of polystyrene (PS) particles at nanometer scale in polypropylene (PP) matrix. Then the PP/PS insulating nanocomposites (containing 10 wt % PS calculated from PS and PP‐g‐PS) are manufactured. With the increase in grafting ratio of PP‐g‐PS, the size of PS particle is reduced and the interfacial adhesion is enhanced. Meanwhile, the dielectric properties, DC breakdown strength and volume resistivity are increased with the decreasing of PS particle size. The spherulite size of PP is decreased and the boundary between crystals and amorphous regions is blurred or even disappears due to the presence of PS nanoparticles. This evolution of PP structure is attributed to the serious entanglements of PP and PS molecular chains. Finally, the correlation between morphological structure and electrical properties is ultimately established based on the in‐depth understanding of the molecular chain movement, crystal structure, and phase morphology. © 2018 Wiley Periodicals, Inc.
