摘要：
The effects of blend ratio, compatibilization and vulcanization on the permeability of O2 and N2 gas through HDPE/EVA blends were analyzed. As the volume fraction of EVA in the blend increases the permeability increases. The variation in permeability is correlated with the phase morphology. Oxygen exhibits a higher permeability than nitrogen because the “kinetic diameter” of N2 is greater than that of O2. The O2/N2 selectivity of HDPE is higher than that of EVA and as a result the selectivity decreases with increase in EVA content in the system. The O2 and N2 permeabilities decrease and O2/N2 selectivity increase upon compatibilization and dynamic vulcanization. The experimental gas permeabilities in HDPE/EVA blends are compared with several theoretical models of permeation.
