“…Polymer nanocomposites have been known as second generation of filled dielectrics in insulation engineering. Many studies have shown that polymer nanocomposites exhibit many superior electrical properties such as higher breakdown strength , lower dielectric permittivity and loss , less space charge accumulation , higher threshold voltage for partial discharge , and less electrical tree formation .…”

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.

“…The second one, the flexible polymer chains of HBP (the shell) in the core–shell particles can contribute to improve the toughness or impact strength of cured epoxy resin thermosets. The last mechanism is that core–shell particles can deflect the crack when it approaches a crack, then increase the fracture surface area and thus increase the fracture energy of the materials .…”

Core–shell particles (CSPs) were prepared by hyperbranched polyesters (HBPs), which synthesized by the polycondensation of succinic anhydride and diethanolamine, grafted on zirconium slag nanoparticles (ZSN), a kind of solid waste in zirconium industry. The CSPs were characterized by attenuated total internal reflectance infrared spectroscopy (ATR‐IR), nuclear magnetic resonance spectroscopy (NMR), high resolution transmission electron micrographs (HRTEM), and thermogravimetric analysis (TGA). Then the effect of CSPs on impact enhancement of epoxy resin thermosets modified by HBP with different kinds of functional terminal groups, such as hydroxyl group, epoxide group, and amino group, was studied. The results indicated that the addition of CSPs resulted to a strong interfacial adhesion and thus improve the impact resistance of epoxy resin thermosets. POLYM.

Reliable methods for tin whisker mitigation are needed for applications that utilize tin-plated commercial components. Tin can grow whiskers that can lead to electrical shorting, possibly causing critical systems to fail catastrophically. The mechanisms of tin whisker growth are unclear and this makes prediction of the lifetimes of critical components uncertain. The development of robust methods for tin whisker mitigation is currently the best approach to eliminating the risk of shorting. Current mitigation methods are based on unfilled polymer coatings that are not impenetrable to tin whiskers. In this paper we report tin whisker mitigation results for several filled polymer coatings. The whisker-penetration resistance of the coatings was evaluated at elevated temperature and high humidity and under temperature cycling conditions. The composite coatings comprised Ni and MgF 2 -coated Al/ Ni/Al platelets in epoxy resin or silicone rubber. In addition to improved whisker mitigation, these platelet composites have enhanced thermal conductivity and dielectric constant compared with unfilled polymers.
