Resumen:
Production of transparent composites from totally renewable resources with extraordinarypotential for different applications can be made possible using cellulose. Composites ofepoxidized soybean oil (ESO)/bacterial cellulose (BC) nanofibers have been prepared with highfiber content. Due to the nano-order scale network-like structure of BC nanofibers, composite films present high transparency even at high BC content. Transparency of films has beenanalyzed by UV-visible spectroscopy observing that only 15 % of matrix transmittance is lost in the nanocomposites. ESO/BC composites show better mechanical properties with increasing BCcontent. Composites combine high stiffness and good ductility due to the incorporation of BC network structure in ESO matrix.
