ConclusionsThe chemical, physical, mechanical and thermal properties ofcellulose/PVA as a biodegradable composite prepared by dissolu-tion in liquid phase were evaluated in this research. The obtainedcomposites showed improved strain at break, preserving the trans-parency and flexibility of the original films. Favorable interfacialproperties and the lack of agglomerations in cellulose/PVA filmswere supposed to explain the high values of the mechanical prop-erties. Cellulose/PVA films showed lower crystallinity than rawand regenerated cellulose, as resulted from XRD analysis. Slightlyhigher onset degradation temperatures were obtained for PVAcomposites
