Abstract

The cellulose nanofibers (CNF) are novelly extracted via air plasma treatment combined with the ultrasonication procedure. This study prepares and characterizes the starch-based biocomposites reinforced by CNF within the glycerol plasticized matrix. The application of starch-based polymers is improved with fabricating a biocomposite of thermoplastic starch (TPS) as matrix and the CNF as reinforcement. After modifying the surface of the cellulose fibers (CF) by air plasma treatment, CNFs are extracted by using an ultrasonic bath. The CNF are studied using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy. The TPS/CNF composites are prepared using the high-friction and hot-compression procedure. Tensile test results and SEM images of the fracture surfaces show significant improvement of adhesion between CNF and TPS matrix compared to composites reinforced by neat CF. The thermogravimetric analysis shows a considerable decompositionat approximately 270–340°C.
