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 ...
Thermoplastic polyurethanes with glycolysate intermediates from polyurethane waste recycling.
(Elsevier, 2017-10)
The polyol is a major component in polyurethane formulations and therefore introducing to the formulation recycled polyol (obtained during decomposition process) allows decreasing the usage of pure petrochemical components. ...
Two different incorporation routes of cellulose nanocrystals in waterborne polyurethane nanocomposites
(Elsevier, 2016-03)
The renewability, availability and low-cost of eco-friendly cellulose nanocrystals (CNC), have gaining attention for nanocomposites preparation due to their unique properties in the nanoscale and their water dispersibility, ...
Properties of flexible polyurethane foams containing isocyanate functionalized kraft lignin
(Elsevier, 2017-02-20)
A commercial kraft lignin (k-lignin) was successfully functionalized by means of the reaction of an isocyanate group from isophorone diisocyanate (IPDI) with hydroxyl groups present in lignin (k-IPDI), for their further ...
