Blend Nanocomposites

A series of polypropylene (PP)/poly(ethylene- co-vinyl acetate) (EVA) blend nanocomposites was produced by utilizing different amounts of organophilic halloysite nanotube (Org-HNT) and EVA-based compatibilizers/tougheners. They were prepared by using either only EVA elastomer or using EVA with the compatibilizers which are maleic anhydride grafted EVA (EVA-g-MA) and poly(ethylene-vinyl acetate-carbon monoxide) (EVACO) as well as maleic anhydride grafted PP (PP-g-MA). The morphology–mechanical property relationship was investigated as a function of nature of the compatibilizer and the amount of aluminosilicate nanotube/compatibilizer. The composites prepared without using the EVA-based compatibilizers in all nanotube loading degrees (1%, 3%, 5%) exhibited nanotube aggregates as evidenced by scanning electron microscope analyses. On the other hand, EVA-g-MA and EVACO provided a good dispersion of HNTs at both PP–EVA interface and in the PP matrix. The use of compatibilizers together with 3% Org-HNT resulted in PP/EVA blend nanocomposites with higher tensile modulus and toughness when compared to PP/EVA blend. Particularly, EVACO compatibilizer having highly polar carbonyl group at its backbone provided the highest toughness and Young’s modulus as well as impact resistance for the 3% Org-HNT loaded nanocomposite while retaining the yield strength as an indication of a good balance between stiffness/toughness.

Cast Technique

In the present study, two different PVA-PEO nanocomposite blend polymer electrolyte systems viz., System-I: [(PVA)(42.5):(PEO)(42.5):(AgNO3)(5):(PEG)(10):(Al2O3)(x)] and System-II: [(PVA)(47):(PEO)(47):(LiCF3SO3)(9):(EC)(6):(Al2O3)(x)] are prepared using solution cast technique for various Al2O3 nanofiller amounts ranging from 2 to 10 wt%. The influence of Al2O3 concentration on the transport properties of the electrolytes of both these systems is closely inspected. Here, the ionic transport number (ti) measurements of the blend specimens are carried out using ‘dc Polarization Technique’.
