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 as regard to reported PVA data, showing an increaseof the thermal stability caused by the addition of cellulose fibers.The biocomposite presented in this study is advanced biomaterialwith large possibilities of application in packaging and other fields.
