in this research, high oxygen-barrier films were organized based on low-density polyethylene (ldpe)/ ethylene vinyl alcohol (evoh)/ polyethylene-grafted maleic anhydride (ldpe-g-ma) compatibilizer. the effects of 10–30 wt. % evoh and 0–10 wt. % ldpe-g-ma loadings on the properties of final films were evaluated. the morphology of specimens was observed by using scanning electron microscopy (sem)...
We present a theoretical approach which maps polymer blends onto mixtures of soft-colloidal particles. The analytical mesoscale pair correlation functions reproduce well data from united atom molecular dynamics simulations of polyolefin mixtures without fitting parameters. The theory exactly recovers the analytical expressions for density and concentration fluctuation structure factors of soft-...
In this era of portability and rapid technological advances, polymers are more than ever under pressure to be cheap and offer tailored property profiles. Often, the key lies in designing blends and alloys carefully structured at the appropriate scale (preferably less than a micrometre) from existing polymers. Block copolymers - two or more different polymer chains linked together - have long be...
