Enhancing thermal and mechanical properties of polypropylene using masterbatches of nanoclay and nano-CaCO3: A review

Abstract

Polymer nanocomposites (PNCs) can be considered as promising relatively new types of composite materials. PNCs give opportunity to develop new composites materials with different structure-property relationships compared to their conventional micro/macro scale composites. Polyolefin based nanocomposites nowadays become more important, because this type of composites has been largely used in various industries. For example, polypropylene based nanocomposites have been widely used in automobile – related industries to replace their conventional composites. This review paper will focus on the polypropylene based nanocomposites prepared using masterbatches of nanoclay and nano-CaCO3 via melt compounding method. The thermal and mechanical properties of such nanocomposites were also discussed.

Studies on thermal and mechanical behavior of nano TiO2 - epoxy polymer composite

“…The permittivity values of epoxy-based nanocomposites have been proven to significantly decrease a wide range of frequencies, and this trend was mainly dependent on the type and size of the incorporated nanoparticle. Various fillers such as SiO2, Al2O3, TiO2, MgO, fly ash, and clay with low concentrations in the base matrix have improved mechanical, thermal, and electrical insulating properties [19][20][21][22] of the various nanoparticles used for high voltage insulation applications, TiO2 nanoparticles are worth mentioning due to their versatile properties including high thermo-mechanical stability, wear resistance, corrosion resistance and wide bandgap. With the right filler concentration in the base matrix, these composites are capable of producing the excellent breakdown strength and lowering dielectric conductivity and permittivity.…”
