Barrier properties of celluloses microfibers (CMF)/ethylene-co-vinyl acetate (EVA)/composites

摘要

The effect of celluloses microfibers (CMF) reinforcement in ethylene-vinyl acetate (EVA) on its barrier properties was evaluated using xylene, toluene, and benzene as penetrant molecule. CMF were obtained from Hibiscus sabdariffa by steam explosion technique and was reinforced in EVA by melt extrusion. The barrier properties of the composites were found to be improved with CMF loading. This has been attributed to good interfacial interaction between CMF and EVA which is further confirmed using Kraus equation. Arrhenius activation parameters for the diffusion, permeation, and thermodynamic parameters were also estimated from the sorption data. The mode of the transport was found to follow regular Fickian trend.
