Abstract

ABSTRACT: Use of inorganic additives in membrane development has been widely employed to improve the performance of polymer membranes. Inorganic additive like hexagonal boron nitride (h-BN) was incorporated in polyvinylidene fluoride (PVDF) to prepare PVDF/h-BN composite membranes. Obtained membranes were characterized using thermogravimetric analysis, scanning electron microscopy (SEM) and atomic force microscopy. The objective was to study the effect of different wt. % of h-BN (0.35, 0.45 and 0.55 wt.%) on single gas (CO2 and CH4 ) transport properties of the composite membrane. The highest permeabilities of 4.30559 × 10 5 and 3.19250 × 10 5 Barrer, for CO2 and CH4, respectively, were achieved using PVDF/h-BN (0.55 wt. %) composite membrane.
