 In this study, scientists used atomic force microscopy, AFM, to investigate the interaction between a lignocellulosic material and a polar matrix. They found that the interactions between the two were stronger when the matrix was made from poly, butylene succinate, a type of plastic, and hyperlignified fibers than when it was made from poly, butylene succinate, and lignified fibers. This suggests that the strength of the bond between the two materials depends on the type of fiber being used. This information can be used to optimize the design of bio-based composites with enhanced characteristics. This article was authored by Carlos Marquello, Bridget Chabert, Francoise Burson, and others.
