The effect of usage of silica nanoparticle filler on increasing the adsorption and flux of CH4 andCO2 in nanocomposite membrane

Silica is one kind of surface modified non-permeable filler which is commonly used for increasing the rate ofadsorption/desorption within nanocomposite membranes. According to the results, application of silicananoparticles increased the rate of flux of gas by surface adsorption. In this article, the simulation was doneby COMSOL software for evaluating the effects of filler on increasing the flux and adsorption rate. In thepresence of filler in the nanocomposite membrane, the flux is much higher than the absence of naoparticlefiller because the adsorption and desorption which happen on the surface of the filler can increase the amountof flux, considerably. On the other words, incorporation of nanoparticle fillers inside polymer matrix,enhances the transport properties of gaseous penetrants and improve their transport fluxes through resultednanocomposite membranes.
