Dielectric analysis of photocrosslinked and post-sulfonated styrene-ethylene-butylene-styrene block copolymer based membranes

Teruel-Juanes, Roberto; Pascual-Jose, B.; del Río, C.; García, O.; Ribes-Greus, A. (Elsevier, 2020-10)

[EN] A series of UV photocrosslinked and post-sulfonated membranes based on blends of styrene-ethylene-butylene-styrene triblock copolymer (SEBS) and divinylbenzene (DVB) were considered for the preparation of electrolytes ...
Dielectric Properties in Oriented and Unoriented Membranes Based on Poly(Epichlorohydrin-co-Ethylene Oxide) Copolymers: Part III

Pascual-Jose, B.; Zare, Alireza; De la Flor, Silvia; Reina, José Antonio; Giamberini, M.; Ribes-Greus, A. (MDPI AG, 2022-04)

[EN] The dielectric spectra and conductivity properties of neat poly(epichlorohydrin-co-ethylene oxide)(PECH-co-EO) copolymer and two modified copolymers with a 20% or 40% of dendron 3,4,5-tris[4-(n-dodecan-1-yloxy)benzyloxy] ...
Dielectric spectroscopy of recycled polylactide

Badía Valiente, José David; Monreal Mengual, Llúcia; Sáenz de Juano Arbona, Víctor; Ribes Greus, María Desamparados (Elsevier, 2014-09)

The effects of multiple mechanical recycling on amorphous polylactide (PLA) were simulated by means of five successive injection-grinding cycles. The influence of the induced thermo-mechanical degradation on the dielectric ...

TERUEL JUANES, ROBERTO; Pascual-Jose, B.; Graf, R.; Reina, J. A.; Giamberini, M.; Ribes-Greus, A. (MDPI AG, 2021-06-13)

[EN] The macromolecular dynamics of dendronized copolymer membranes (PECHs), obtained by chemical modification of poly(epichlorohydrin) with the dendron 3,4,5-tris[4-(n-dodecan-1-yloxy)benzyloxy] benzoate, was investigated. ...
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 ...
Molecular Mobility in Oriented and Unoriented Membranes Based on Poly[2-(Aziridin-1-yl)ethanol]

Teruel-Juanes, Roberto; Bogdanowicz, Krzysztof Artur; Badia, José D.; Sáenz de Juano-Arbona, Victor; Graf, Robert; Reina, José A.; Giamberini, Marta; Ribes-Greus, Amparo (MDPI AG, 2021-04)

[EN] Unoriented and oriented membranes based on dendronized polymers and copolymers obtained by chemical modification of poly[2-(aziridin-1-yl) ethanol] (PAZE) with the dendron 3,4,5-tris[4-(n-dodecan-1-yloxy)benzyloxy]benzoate ...
The role of crystalline, mobile amorphous and rigid amorphous fractions in the performance of recycled poly (ethylene terephthalate) (PET)

Badia, J.D.; Strömberg, Emma; Karlsson, Sigbritt; Ribes-Greus, A. (ELSEVIER SCI LTD, 2012)

[EN] The action of thermo-mechanical degradation induced by mechanical recycling of poly(ethylene terephthalate) was simulated by successive injection moulding cycles. Degradation reactions provoked chain scissions and a ...
