Copolímeros de poliuretano del tipo poli[(hexametilen-carbamato- butanodiol)-co-(carbonato-co-éster)]
(Universidad Industrial de Santander, 2016-12)
Resumen Los poliuretanos segmentados termoplástico elastoméricos (PUSTE) comprenden una familia de materiales muy versátiles debido a su potencial empleo en diversos campos tales como biomedicina. Entre los PUSTE los ...
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, ...
