An Alternative Approach for the Incorporation of Cellulose Nanocrystals in Flexible Polyurethane Foams Based On Renewably Sourced Polyols
(Elsevier, 2016-11-16)
Este trabajo analiza tanto el efecto de los nanocristales de celulosa en las propiedades finales de espumas flexibles de poliuretano basadas en castor oil y maíz, sino que además se realiza un análisis en profundidad sobre ...
Cellulose nanocrystals reinforced environmentally-friendly waterborne polyurethane nanocomposites
(Elsevier, 2016-10)
Focusing on eco-friendly materials, cellulose nanocrystals (CNC) have gained attention as nanoreinforcement due to their exceptional properties conferred by the elevated length/diameter aspect ratio and high specific ...
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, ...
Shape-memory properties of crosslinked biobased polyurethanes
(2016-03-25)
Biobased crosslinked polyurethanes were synthesized and characterized as shape-memory polymers. Both the macrodiol and the diisocyanate were derived from renewable sources; the first one from castor oil, and the second one ...
Synthesis and characterization of polyurethanes with high renewable carbon content and tailored properties.
(2016-08-31)
Thermoplastic and cross-linked biobased polyurethanes with a renewable carbon content ranging from 78 to 98% were synthesized and characterized. The macrodiol and the diisocyanate used were derived from renewable source, ...
Synthesis of waterborne polyurethane-urea dispersions with chain extension step in homogeneous and heterogeneous media
(Elsevier, 2016-05-13)
[EN Hypothesis: The possibility of tailoring the final properties of environmentally friendly waterborne
polyurethane and polyurethane-urea dispersions and the films they produce makes them attractive for
a wide range ...
