Abstract

Carboxymethyl cellulose is a polysaccharide which forms strong and clear films. MONTMORILLONITE and CELLULOSE NANOWHISKERs are two types of nanoparticles with sheet and rod geometric shapes, respectively. MONTMORILLONITE is nonrenewable and non-biodegradable and CELLULOSE NANOWHISKERs are renewable and biodegradable filler. CELLULOSE NANOWHISKERs are not produced commercially and in this research we prepared them from cotton linter. Atomic Force Microscopy (AFM) and Transmission Electron Microscopy (TEM) indicated that the prepared nonowhiskers suspernsion having an average length of 240 nm and diameter of 13 nm respectively. In this study, carboxymethyl cellulose (CMC)-Polyvinyl alcohol (PVA) nanocomposite films, containing 3-10% nanoparticles (W/W CMC), were prepared by casting method and their physical properties were compared. In comparison to control film, 28.21% reduction in Water Vapor PERMEABILITY (WVP) was observed in the films containing 10% Wt cellulose nonowhiskers and samples with 7% CELLULOSE NANOWHISKERs, whowed the lowest surface hydrophilicity (contact angle=59.28o). On the other hand, nanocomposite containing 10% MONTMORILLONITE exhibited 29.06% reduction in WVP compared to the control film samples with 10% MONTMORILLONITE, shwed the lowest surface hydrophilicity (contact angle=65.09o). Significant difference in WVP value and contact angle of two types of nanocomposit only observed at 3 and 10% content of nanoparticles, respectively, by Duncan test (P<0.05). Differential Scanning Calorimetry (DSC) results indicated that the incorporation of nanoparticles caused and increase in glass transiton temperature (Tg) of the resulted nanocomposite films. The glass transition disappeared gradually and no glass transition was observed in the thermograms of the films containing higher amount of nanoparticles. Adding of nanoparticles caused to decrease in melting point of the both type of films.
