A tough and sustainable fiber-forming material from lignin .

Brittle lignin oligomers isolated from plant biomass require a low-melting host polymer matrix to form a rigid and tough renewable material. We demonstrate controlled lignin dispersion and interfacial interactions in softened recycled polyethylene terephthalate PET using a simple solvent-free melt-blending technique.【Get Price】

Macroscopic Behavior of Kraft Lignin Fractions: Melt .

Questions that pertain to the behavior of softwood kraft lignin fractions as opposed to the whole lignin still prevail. In an effort to further understand such effects at a macroscopic level we have examined the issue of melt stability of polyethylene PE in blends with fractionated and unfractionated softwood kraft lignin.【Get Price】

Lignin Functionalization for the Production of Novel Materials

Lignin a major constituent of lignocellulosic biomass is the largest natural source of aromatic molecules and thus is an attractive feedstock for renewable chemical production. Direct incorporation of isolated lignin into materials has long been researched due to the idea’s simplicity and the scheme’s potentially high atom economy. However due to its high chemical reactivity lignin is .【Get Price】
