Effect of incorporation of microstructured carbonized cellulose on surface and mechanical properties of epoxy composites

In this study, we reported the use of cellulose derived microstructured biochars for the production of reinforced plastics. Cel-lulose nanocrystals and wasted cottonfibers were used as cellulose template structures and converted into carbonaceous materials underpyrolytic conditions. Biochars particles were produced with the shape of deformed spheres or rods and dispersed into an epoxy matrixwith a loading ranging from 1 wt % to 10 wt %. Biochar-based composites showed remarkably elongation properties of up to 8.2% using2 wt % of carbonized cellulose nanocrystals and a very low friction coefficient of 0.22 using 10 wt % of carbonized cottonfibers
