Study of dielectric relaxations in zinc oxide-epoxy resin nanocomposites

Study of relaxations in epoxy polymer by thermally stimulated depolarization current (TSDC) and dielectric relaxation spectroscopy (DRS)

“…2(b) and (c)) show two overlapped relaxation peaks. The lower temperature peak around 48 • C corresponds to the ␣ relaxation and the second one is attributed to the interfacial Maxwell Wagner Sillars relaxation (MWS) as examined in our previous paper [17]. It is due to the accumulation of charges at the interfaces during the polarization stage.…”

Fabrication of graphene oxide–alumina hybrids to reinforce the anti-corrosion performance of composite epoxy coatings

“…Epoxy resins, have been widely used in industrials for adhesives, coatings, structural materials and composite matrix, due to its excellent chemical and corrosion resistance, outstanding adhesion properties, low shrinkage and low price [1][2][3][4]. Unfortunately, these epoxy resins are inherently brittle, and micro-pores are inevitably produced in service due to the solvent evaporation when fabricating the high temperature curing epoxy solvent-borne coatings, which may reduce hardness and anti-corrosion performance.…”

“…While there are many examples of other nanoparticles used for grafting GO, such as silica, titanium oxide, and zinc oxide [4,24,27], there are relatively few reports that mention GO grafted with nano-Al 2 O 3 .…”

Effect of Aluminium Hydroxide on Thermal, Dynamic Mechanical and Dielectric Properties of Hexafluoropropylene-vinylidinefluoride Elastomeric Composites

“…With increase in filler volume fractions the space charge getting accumulated in the interfacial area increases, leading to an increase in dielectric loss. However, this interfacial effect is effective only at low frequencies [36].…”
