Abstract
AbstractComposite films based on poly(ethylene‐co‐vinyl acetate) (EVA) and cellulose derived from banana plant waste have been prepared and characterized. Cellulose whiskers isolated from, banana fibers, by an acid hydrolysis method and were incorporated into the EVA matrix by solution casting technique. The composite films were subsequently examined by scanning electron microscopy, thermogravimetry, differential scanning calorimetry, and FTIR spectroscopy. Compared with pure EVA and cellulose, the EVA/cellulose composite systems showed superior thermal stability. The mechanical testing of the composite films revealed that the tensile strength and elastic modulus were increased after cellulose incorporation into EVA. Among the EVA/cellulose composites, 7.5% cellulose loaded EVA showed the highest tensile strength. The percentage strain at break of the EVA/cellulose composite systems was found to be decreased which has been attributed to the restricted mobility of the polymer matrix by the presence of cellulose. X‐ray diffraction studies showed that the EVA/cellulose composites were more crystalline than EVA. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2012
