Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>Cellulose acetate–titania (CA–TiO₂) nanoparticles blended membranes were fabricated using diffusion‐induced phase separation process to observe the effect of inorganic nanofillers on the surface topography and gas permeation properties of CA membrane. Self‐synthesized TiO₂ nanoparticles using sol gel reflux condensation were employed as nanofillers, which is the anatase phase of TiO₂ with crystallite size of 5–10 nm. The synthesized membranes were characterized using scanning electron microscopy and atomic force microscopy techniques to study the nanoscale distribution of TiO₂ nanoparticles, surface roughness, and pores generation in blended membranes, with increasing nanoparticles' concentration in polymer matrix. The permeability of CO₂ was found to be increased for CA–TiO₂ blended membranes. The CO₂/CH₄ selectivity up to 23.3 was documented. © 2014 Curtin University of Technology and John Wiley &amp; Sons, Ltd.</p> </abstract>
