Modification of Pea Starch and Dextrin Polymers with Isocyanate Functional Groups
(MDPI, 2018-09)
Pea starch and dextrin polymers were modified through the unequal reactivity of isocyanate groups in isophorone diisocyanate (IPDI) monomer. The presence of both urethane and isocyanate functionalities in starch and dextrin ...
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 ...
Bacterial nanocellulose production from naphthalene
(Wiley, 2019-07)
Polycyclic aromatic compounds (PAHs) are toxic compounds that are released in the environment as a consequence of industrial activities. The restoration of PAH-polluted sites considers the use of bacteria capable of degrading ...
Towards Circular Economy: Different Strategies for Polyurethane Waste Recycling and the Obtaining of New Products
(MDPI, 2018-11-22)
As a consequence of the high production and simultaneous consumption of polyurethanes
(PU) a great volume of PU waste is landfilled. In this scenario, suitable and efficient routes for PU
waste recycling have been searched ...
Lignocellulosic Biomass as a Source of Raw Materials for the Synthesis of Polyurethanes
(MDPI, 2018-11-06)
Precursors have been satisfactorily synthesized from lignocellulosic biomass for later use in the synthesis of polyurethanes resulting in competitive final properties with those of petroleum derived polyurethanes
Genome sequence and characterization of the bcs clusters for the production of nanocellulose from the low pH resistant strain Komagataeibacter medellinensis ID13488
(Wiley, 2019-02-22)
Komagataeibacter medellinensis ID13488 (formerly Gluconacetobacter medellinensis ID13488) is able to produce crystalline bacterial cellulose (BC) under high acidic growth conditions. These abilities make this strain desirable ...
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 ...
Strain sensitive conductive polyurethane foam/graphene nanocomposites prepared by impregnation method
(Elsevier, 2017-03-14)
Se prepararon nanocompuestos de espuma de poliuretano conductores mediante la incorporación de flakes de grafeno. Los flakes de grafeno se obtuvieron a partir de grafito por el método de exfoliación líquida en N metilpirrolidona ...
Tailoring Mechanical Properties of Rigid Polyurethane Foams by Sorbitol and Corn Derived Biopolyol Mixtures
(ACS, 2015-10-28)
Sorbitol arises to be a strong candidate for renewably sourced polyol synthesis. Moreover, processes for extracting sorbitol directly from cellulosic materials are effective, and materials such as agroforestry residues ...
