“…17 As estimated by Regnaud et al, 18 an interphase of 1 nm thickness represents roughly 0.3% of the total volume of polymer in the case of microparticles filled composites, whereas, it can be 30% of the total volume in the case of nanocomposites. Uniform distribution of nanoparticles over a polymer matrix has become mandatory to improve nanopartiles/matrix interaction.…”

The present study was aimed to see the effect of surface treatment on nanocomposites with different fatty acids (stearic acid and oleic acid) having two different coupling agents (titanate and silane). Nanocomposites were prepared via melt mixing in Haake 90 twin screw extruder. The characterization of nanocomposites had been carried out using various advance analytical techniques such as dynamic mechanical analysis, thermogravimetric analysis, heat distortion temperature, melt flow index, and scanning electron microscopy. The strength and stiffness were also improved with the incorporation of maleic-anhydride grafted ethylene propylene rubber in PP/ Nano-CaCO 3 nanocomposites. The tensile, flexural, and impact strength properties of PP/MA-g-EPR/treatedCaCO 3 and untreated nanocomposites were determined. These studies revealed that stearic acid treated nanofiller filled composites had better properties than those of untreated and oleic acid treated nanofiller filled composites. The SEM studies demonstrated that the dispersion and distribution of Nano-CaCO 3 (nCaCO 3 ) particles within the polypropylene matrix were dependent on the nature of surface treating agents.

The effects of heat treatment on the crystal structure and impact strength of poly(phenylene sulfide) (PPS) and nano‐SiOx/ PPS nanocomposites were studied. The molecular weight of heat‐treated neat PPS was increased by 28% due to the crosslinking reaction that changed its crystal morphology. Also, the crystallinity was reduced by 18%, leading to an improvement of the Izod impact strength by 66%. Nano‐SiOx/PPS composites were manufactured by intensive compounding with 3 wt.‐% nano‐SiOx particles treated by an epoxy functional group. Test results showed that the Izod impact strength of nano‐SiOx/heat‐treated PPS composites was 91% better and the crystallinity 27% less compared to the same properties of “as received” neat PPS. Nano‐SiOx has a high specific surface area and a high surface energy; its grafted epoxy group promotes interfacial adhesion with the PPS matrix, hence increasing the Izod impact strength of the nanocomposites.TEM micrograph of NHTM‐PPS with 3 wt.‐% nano‐SiOx.magnified imageTEM micrograph of NHTM‐PPS with 3 wt.‐% nano‐SiOx.
