The addition of charcoal fines can increase the photodegradation resistance of polymeric biocomposites

This study aims to analyze the addition of widely available, cheap, and biologically-based 12 residues, such as charcoal fines, in the production of polymeric biocomposites reinforced with nat-13 ural fibers subjected to UV-c radiation. The addition of charcoal fines was 0, 10, 20, 30% in the pol-14 ymeric matrix of the biocomposites. Mechanical and chemical properties of the biocomposites were 15 evaluated. The flexural strength was more resistant when subjected to UV-c radiation with 20% 16 filling. These results attested that biocomposites with the addition of vegetative charcoal fines were 17 less susceptible to photodegradation.
