Water Uptake Behavior and Young Modulus Prediction of Composites Based on Treated Sisal Fibers and Poly(Lactic Acid)
(MDPI, 2016-05)
The main aim of this work was to study the effect of sisal fiber surface treatments on water uptake behavior of composites based on untreated and treated fibers. For this purpose, sisal fibers were treated with different ...
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 ...
Synthesis and characterisation of polyurethane elastomers with semi-products obtained from polyurethane recycling.
(2016-10-01)
In this work polyurethane elastomers were synthesised by using different mixtures of a petrochemical and glycerolysate polyols and 4,4-diphenylmethane diisocyanate (MDI). Glycerolysate polyol was produced from polyurethane ...
