Sustainable hemp fiber reinforced polylactic acid/poly(butylene succinate) biocomposites: Assessing the effectiveness of MAH‐g‐PLA as a compatibilizer

Polymer Composites, EarlyView.
Production of biocomposites. Abstract The unsustainability of petroleum resources and the growing issue of plastic pollution necessitate the development of sustainable biocomposites as alternatives to synthetic materials. On this basis, a blend of biosourced poly(lactic acid) (PLA)/poly(butylene succinate) was reinforced with hemp fibers (HF) in ...
