A statistical design of experiments for optimizing the MALDI-TOF-MS sample preparation of polymers. An application in the assessment of the thermo-mechanical degradation mechanisms of poly (ethylene terephthalate)

Badía Valiente, José David; Strömberg, Emma Marie; Ribes Greus, María Desamparados; Karlsson, Sigbritt (ELSEVIER SCIENCE BV, 2011)

[EN] The sample preparation procedure for MALDI-TOF MS of polymers is addressed in this study by the application of a statistical Design of Experiments (DoE). Industrial poly (ethylene terephthalate) (PET) was chosen as ...
Assessing the MALDI-TOF MS sample preparation procedure to analyze the influence of thermo-oxidative ageing and thermo-mechanical degradation on poly (Lactide)

Badia, J.D.; Strömberg, Emma Marie; Ribes Greus, María Desamparados; Karlsson, Sigbritt (Elsevier, 2011)

[EN] Multiple processing by means of successive injection cycles was used to simulate the thermo-mechanical degradation effects on the oligomeric distribution of PLA under mechanical recycling. Likewise, an accelerated ...
Degradation of a mechanically recycled polylactide/halloysite nanocomposite in an ethanolic food simulant

Beltrán, Freddys R.; Arrieta, Marina P.; Hortal, Yaiza; Gaspar, Gerald; de la Orden, Mª Ulagares; Martínez Urreaga, Joaquín (Universitat Politècnica de València, 2021-07-16)

[EN] This work aims to study the effect of immersion in a ethanolic food simulant in mechanically recycled poly(lactic acid) (PLAR) and its nanocomposites reinforced with halloysite nanotubes (HNT). PLAR was obtained by ...
Estudio de parámetros significativos para la optimización del uso del polietileno de alta densidad (HDPE) reciclado en diversas aplicaciones industriales

Montés Gandia, Noelia (Universitat Politècnica de València, 2021-03-05)

[ES] El continuo crecimiento de la población e industria ha dado lugar a un aumento en el consumo de productos plásticos, generando como consecuencia una abundante corriente de residuos que da lugar a diversos problemas ...
Management of composite waste from wind turbine blades: Identification of possible routes and calculation of the quality of recycling

Estañ Lloret, Mercedes (Universitat Politècnica de València, 2023-09-20)

[ES] El objetivo de este estudio es la identificación de posibles rutas de reciclaje y el cálculo de la calidad del reciclaje para los residuos compuestos de las palas de los aerogeneradores. Actualmente, se puede ...
Material valorisation of amorphous polylactide. Influence of thermo-mechanical degradation on the morphology, segmental dynamics, thermal and mechanical performance

Badía Valiente, José David; Strömberg, Emma; Karlsson, Sigbritt; Ribes Greus, A. (ELSEVIER SCI LTD, 2012-04)

[EN] This paper reports the effects of multiple mechanical recycling on the structure and properties of amorphous polylactide (PLA). The influence of the thermo-mechanical degradation induced by means of five successive ...
Process behavior of compatible polymer blends

Navarro Vidal, Raúl; López Martínez, Juan; Parres, F.; Ferrándiz Bou, Santiago (Wiley-Blackwell, 2012-05-05)

It is a common industrial practice to blend virgin polymer with the same polymer recycled from scrap plastic that, in general, has not undergone relevant degradation. In this article, the influence that incorporating ...
Rheological behavior of recycled polypropylene for reuse in the automotive sector

Ferrándiz Bou, Santiago; López Martínez, Juan; Navarro Vidal, Raúl; Parres, F. (INOE Publishing House, 2011-07)

This work shows the study of rheological behavior of a material that recycled materials have been incorporated. The transformation process to be applied is the injection molding. The mix of materials used was of the same ...
Structure-Properties Relationship of Reprocessed Bionanocomposites of Plasticized Polylactide Reinforced with Nanofibrillated Cellulose

Gil-Castell, O.; Wolf, Mark Henning; Cea, J.; Carrasco, J. C.; Giaccinti Baschetti, M.; Ribes-Greus, A. (MDPI AG, 2022-12)

[EN] Bionanocomposites of polylactide (PLA), plasticized with poly(ethylene glycol) (PEG) (7.5 wt%, 400 and 1500 g/mol) and reinforced with nanofibrillated cellulose (NFC) (1, 3, and 5 wt%) were sequentially compounded, ...
Study of the Influence of the Reprocessing Cycles on the Final Properties of Polylactide Pieces Obtained by Injection Molding
