Ice-template crosslinked PVA aerogels modified with tannic acid and sodium alginate
(Multidisciplinary Digital Publishing Institute (MDPI), 2022-07-01)
Article
Open AccessWith the commitment to reducing environmental impact, bio-based and biodegradable aerogels may be one approach when looking for greener solutions with similar attributes to current foam-like materials. This study aimed to ... -
Characteristic time of strain induced crystallization of crosslinked natural rubber
(Elsevier, 2012-06)
Article
Open AccessReal time Wide-Angle X-ray Scattering (WAXS) measurements during cyclic tensile tests at high strain rates (from 8 s-1–280 s-1) and at room temperature on crosslinked Natural Rubber (NR) are performed thanks to a specific ... -
Strain-induced crystallization of natural rubber and cross-link densities heterogeneities
(American Chemical Society (ACS), 2014-08-26)
Article
Open AccessStrain-induced crystallization (SIC) of natural rubber (NR) is characterized during a cyclic deformation at room temperature and low strain rate (~10–3 s–1) using in situ wide angle X-rays scattering (WAXS) measurements. ... -
Strain induced crystallization and melting of natural rubber during dynamic cycles
(Royal Society of Chemistry (RSC), 2015)
Article
Open AccessStrain-induced crystallization (SIC) of natural rubber (NR) is studied during dynamic cycles at high frequencies (with equivalent strain rates ranging from 7.2 s-1 to 290 s-1). The testing parameters are varied: the ... -
EcoBlends’up: PLA/BioPA blends composites, microfibrillated “in situ” through additive manufacturing
(2022-04)
Article
Restricted access - publisher's policyIn certain polymer blends, a properly oriented microfibrillar morphology of the dispersed phase during the processing stage can generate a reinforcing effect by increasing the fracture toughness, especially in the crack ... -
Influence of the melt extrusion process on the mechanical behavior and the thermal properties of ethylene vinyl alcohol copolymer by applying the successive self-nucleation and annealing thermal fractionation
(2021-04-26)
Article
Open AccessEthylene vinyl alcohol copolymer was processed three times in a twin-screw extrusion pilot plant in order to reproduce the processing steps required to obtain EVOH nanocomposites. Thin film of the extruded EVOH was prepared ... -
Poly (Lactic Acid)/Ground Tire Rubber blends using peroxide vulcanization
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-05-06)
Article
Open AccessPoly (Lactic Acid) (PLA)/Ground Tire Rubber (GTR) blends using Dicumyl peroxide (DCP) as a crosslinking agent were prepared with the following aims: propose a new route to recycle wastes rubber from the automotive industry ... -
Hydrostatic pressure dependence in tensile and compressive behavior of an acrylonitrile–butadiene–styrene copolymer
(Wiley, 2022-02-26)
Article
Open AccessThe strain-rate dependence of a commercial grade ABS copolymer has been analyzed in both compression and tension. By measuring in two loading geometries, the hydrostatic pressure-dependence on the material's deformation ... -
Orientation of polylactic acid–chitin nanocomposite films via combined calendering and uniaxial drawing: Effect on structure, mechanical, and thermal properties
(2021-12-06)
Article
Open AccessThe orientation of polymer composites is one way to increase the mechanical properties of the material in a desired direction. In this study, the aim was to orient chitin nanocrystal (ChNC)-reinforced poly(lactic acid) ... -
Kinetics of the thermal degradation of poly(Lactic acid) and polyamide bioblends
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-11-19)
Article
Open AccessPoly(lactic acid) (PLA) and biosourced polyamide (PA) bioblends, with a variable PA weight content of 10–50%, were prepared by melt blending in order to overcome the high brittleness of PLA. During processing, the properties ... -
Elastocaloric effect in vulcanized natural rubber and natural/wastes rubber blends
(Elsevier, 2021-11-30)
Article
Restricted access - publisher's policyVulcanized natural/wastes rubber blends were prepared and their elastocaloric properties were analysed. A thermodynamic frame was used to discriminate the contributions of thermoelastic effects and strain induced ... -
Structure and properties of reactively extruded opaque post-consumer recycled PET
(Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-01)
Article
Open AccessThe recyclability of opaque PET, which contains TiO2 nanoparticles, has not been as well-studied as that of transparent PET. The objective of this work is to recycle post-consumer opaque PET through reactive extrusion with ...
