High bio-content polyurethane composites with urethane modified lignin as filler
In order to improve the compatibility between lignin fillers and polyurethane matrix, two different chemical strategies were used to modify the lignin macromolecules. Modified lignin was incorporated into vegetable oil-based ...
Bio-renewable precursor fibers from lignin/polylactide blends for conversion to carbon fibers
Lignin, a highly aromatic biopolymer extracted as a coproduct of wood pulping, was investigated as a suitable precursor for carbon fibers. Lignin was chemically modified and blended with poly(lactic acid) (PLA) biopolymer ...
