Advances in Waterborne Polyurethane and Polyurethane-Urea Dispersions and Their Eco-friendly Derivatives: A Review
(MDPI, 2021-01-27)
Polyurethanes and polyurethane-ureas, particularly their water-based dispersions, have gained relevance as an extremely versatile area based on environmentally friendly approaches. The evolution of their synthesis methods, ...
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 ...
Residues from rigid foams and graphene for the synthesis of hybrid polyurethane flexible foams composites
(Elsevier, 2021-06)
Hybrid biobased polyurethane flexible foam composites containing a residue from surf industry (polyurethane powder) as filler and graphite or graphene residue were synthe-sized. It was observed that the addition of the ...
Bacterial-Cellulose-Derived Carbonaceous Electrode Materials for Water Desalination Via Capacitive Method: the Crucial Role of Defect Sites
(Elsevier, 2020-10-15)
Electrosorptive desalination is a very simple and appealing approach to satisfy the increasing demand for drinking water. The large-scale application of this technology calls for the development of easy-to-produce, cheap ...
Influence of Process Parameters in Graphene Oxide Obtention on the Properties of Mechanically Strong Alginate Nanocomposites
(MDPI, 2020-02-28)
Sodium alginate, a biopolymer extracted from brown algae, has shown great potential for many applications, mainly due to its remarkable biocompatibility and biodegradability. To broaden its fields of applications and improve ...
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 ...
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 ...
