[EN] A comparative study of the relaxational behavior of amorphous and partially crystalline poly(ethylene-2,6-naphthalene dicarboxylate) (PEN), has been carried out by thermally stimulated depolarization currents (TSDC), ...
Water absorption in chitosan rapidly increases when the deacetylation degree decreases between 85
and 45%. This seems to contradict the fact that water absorption in chitin is much lower than that of
chitosan. The aim ...

[EN] Poly(3-hydroxybutyrate-co-3-valerate) (PHBV), being one of the most studied and commercially available polyhydroxyalkanoates (PHAs), presents an intrinsic brittleness and narrow processing window that currently hinders ...
[EN] Mainly due to environmental aims, petroleum-based plastics are being replaced by natural polymers. In the last decades, starch has been evaluated in its film-forming ability for applications in the food packaging area. ...
Vila Montalt, Rubén(Universitat Politècnica de València, 2022-10-20)
[ES] El gran aumento en la producción y consumo de plásticos ha generado un grave problema medioambiental por su incapacidad de biodegradación. Por ello se han puesto en marcha diferentes estrategias como el reciclaje y ...
[EN] Cinnamic and ferulic acid were incorporated into highly hydrolysed and partially acetylated poly (vinyl alcohol) (PVA) for the purpose of obtaining active films. The microstructure, crystallinity, tensile and barrier ...
[EN] The dielectric properties of virgin polylactide (PLA) and its reinforced composites with different weight amounts of sisal fibres were assessed at broad temperature (from - 130 degrees C to 130 degrees C) and frequency ...
[EN] Aligned mats of poly(lactic acid) (PLA) nanofibers containing nanosized hydroxyapatite filler have been obtained via electrospinning onto a rotating mandrel. Their structure and morphology have been characterized as ...
Delgado Fernández, Andrea(Universitat Politècnica de València, 2022-04-08)
[ES] Aunque tradicionalmente los tratamientos térmicos han sido vinculados a materiales metálicos, estos pueden ser aplicados a cierto grupo de polímeros. Dentro de los polímeros se encuentra un grupo denominado termoplásticos, ...
[EN] The influence of an accelerated hygrothermal ageing simulation test on a commercial PLA and its three
subsequent mechanically-reprocessed materials was studied. The analysis was focused on the water
diffusion kinetics ...
Chitosan fiber mats were successfully processed by electrospinning. The as-spun fiber mats were neutralized with ethanol and cross-linked with glutaraldehyde. A decrease of the fiber average diameter from 243 +/- 43 nm ...
[EN] PHBV films incorporating 3, 6 and 9% ferulic acid (FA) or p-coumaric acid (PCA) were obtained by melt blending and compression moulding. The films¿ microstructures and thermal behaviours were analysed as well as their ...
Jiménez Marco, Alberto(Universitat Politècnica de València, 2013-04-25)
Abstract
Biodegradable starch-glycerol based films were obtained. The influence of lipid compounds (palmitic, stearic and oleic acid), other polymers (hydroxypropylmethylcellulose and sodium caseinate) and bioactive ...

[EN] Biodegradable poly(L-lactic acid) (PLLA) microfibers were prepared by electrospinning by varying the applied potential, solution flow rate and collector conditions. PLLA fibers with smoothly oriented and random ...
[EN] Cellulose nanocrystals (CNCs) are attractive materials due to their renewable nature, high surface-to-volume ratio, crystallinity, biodegradability, anisotropic performance, or available hydroxyl groups. However, their ...
