Kraft lignin as filler in PLA to improve ductility and thermal properties
(Elsevier, 2015-10)
[EN] Kraft lignin (KL) and acetylated Kraft lignin (AKL) were used as filler for the elaboration of composites
with poly(lactic acid) (PLA) in different concentrations (0.5, 1, 5, 10 and 20%) by extrusion method at
200 ...
Thermally-responsive biopolyurethanes from a biobased diisocyanate
(Elsevier, 2015-09)
In this work, segmented biopolyurethanes with thermally-activated shape-memory properties were synthesized and characterized. All the employed starting materials were derived from renewable sources. The macrodiol, which ...
Selective placement of magnetic Fe3O4 nanoparticles into the lamellar nanostructure of PS-b-PMMA diblock copolymer
(Elsevier, 2015-04-27)
The aim of this work is to obtain a good and selective dispersion of Fe3O4 magnetic nanoparticles into the lamellar morphology of PS-b-PMMA diblock copolymer. The addition of unmodified nanoparticles inhibited the formation ...
Simultaneous catalytic de-polymerization and hydrodeoxygenation of lignin in water/formic acid media with Rh/Al2O3, Ru/Al2O3 and Pd/Al2O3 as bifunctional catalysts
(Elsevier, 2015-04-28)
[EN] The catalytic solvolysis of 3 lignins of different sources in a formic acid/water media using bifunctional Ru/Al2O3, Rh/Al2O3, Pd/Al2O3 catalysts was explored in a batch set-up at different temperatures and reaction ...
Study of the influence of reutilization ionic liquid on lignin extraction
(Elsevier, 2015-04-09)
The development of green techniques for biomass processing and fractionation is crucial from the point of view of sustainability and environmental protection. Lignin is the second most abundant bio-renewable material on ...
