Possible mechanisms of superior resistance of polyamide nanocomposites to partial discharges and plasmas

Tribological properties and insulation effect of nanometer TiO2 and nanometer SiO2 as additives in grease

“…Fast electron could float rapidly from high electric field to low electric field, and finally lead to the electrical channel develops faster. Also microparticles can introduce many defects which help electrons float through easily and lead to the reduction in breakdown strength and volume resistivity of the base matrix [26,27].…”

Space charge evolution in polypropylene containing synthetic and natural organoclays

“…Since most of polymer nanocomposites are electrically insulating and the electrical power industry already uses large quantities of polymeric materials as electrical insulation, the efforts to determine whether the PNCs could also posses better dielectric properties and find wider application in the electrical industry area were inevitable. Some of the recently published data suggest that the PNCs do in fact have better electrical breakdown strength, surface and volume resistivity, space charge mitigation characteristics [1][2][3], resistance to partial discharges [4][5][6][7][8], etc.…”

Dielectric properties of polypropylene containing synthetic and natural organoclays

“…A polymer such as polypropylene can be reinforced with small quantities of nano-sized particles to achieve not only better chemical, thermal and mechanical properties but also, as some of the recent published data suggest, to improve dielectric properties, such as electrical breakdown strength, surface and volume resistivity, space charge and polarization characteristics [2][3][4], resistance to partial discharges [5][6][7][8], etc.…”
