    Effect of copolymer composition on free volume and gas

    Similar behaviour has been observed in partially miscible blends [18] and suggests the presence of PCT-rich and PET-rich regions as expected in the copolymer. Since T3 and 73 both increase with CHDM content, the effect of copolymer composition on transport properties is easy to predict.

    Effect of Grafted Copolymer Composition on Iron Oxide

    The transport of engineered nanoparticles in porous media is of interest in numerous applications including electromagnetic imaging of subsurface reservoirs, enhanced oil recovery, and CO2 sequestration. A series of poly(2-acrylamido-2-methyl-1-propanesulfonic acid-co-acrylic acid) (poly(AMPS-co-AA)) random copolymers were grafted onto iron oxide (IO) nanoparticles (NPs) to provide colloidal

  • effect of copolymer composition, temperature, and carbon

    Effect of copolymer composition, temperature, and carbon

    However, as shown here, the three factors influencing gas transport correlate well with free volume, and a simplified free volume model with only two adjustable parameters can satisfactorily describe the effects of copolymer composition, temperature, and CO 2 fugacity on pure- and mixed-gas transport properties.

    The effects of humidity on gas transport properties

    The magnitude of the permeability coefficient variation depends on the gas polarity and on the copolymer composition. A detailed analysis of the gas transport properties at anhydrous state and of the water sorption mechanism as a function of the copolymers composition allows to explain all the gas permeability variations as a function of hydration.
