Studies on the thermal, mechanical, compatibility, and morphological properties of zinc-neutralized ethylene/methacrylic acid copolymer ionomer blend withm-aramid

A series of binary composite blends ofm-aramid/zinc ionomer (m-Ar/ZnI) with different weight ratio were prepared by the solution blend technique. These composite films were characterized in terms of the structure, crystallinity, morphology, thermal, and mechanical properties. The temperature corresponding to 5% (T-5%) weight loss are in the range of 101-438 degrees C. The composite films showed good storage modulus (in the range of 2.1-3.1 GPa) and high glass transition temperature (T-g) (in the range of 254-278 degrees C) and exhibited good tensile strength but it decreased with an increase in the content of ZnI. The strong compatibilizing effect was observed between them-Ar and ZnI components, where exceptionally self-assembled morphology was formed in them-Ar/ZnI composite films. The most favorable mechanical and thermal data supported by the finest structure were observed with 3:0.50 weight ratio. This study evaluates the efficiency of ionomer inm-Ar/ZnI composite blends.
