A comparison of the abilities of natural rubber (NR) and synthetic polyisoprene cis-1,4 rubber (IR) to crystallize under strain at high strain rates
(Royal Society of Chemistry (RSC), 2016)
Article
Open AccessStrain induced crystallization (SIC) of a natural rubber (NR) and a synthetic rubber (IR) with a high amount of cis-1,4 units (98.6%) is studied, thanks to in situ wide angle X-ray (WAXS) experiments at room temperature ... -
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 ... -
Compared abilities of filled and unfilled natural rubbers to crystallize in a large strain rate domain
(2015-02)
Article
Open AccessStrain induced crystallization (SIC) in filled and unfilled natural rubbers is investigated through in¿situ wide angle X-rays scattering (WAXS) experiments at various strain rates. The values of local stretching ratio at ... -
Complex dependence on the elastically active chains density of the strain induced crystallization of vulcanized natural rubbers, from low to high strain rate
(Elsevier, 2016-08)
Article
Open AccessStrain Induced Crystallization (SIC) of Natural Rubbers (NR) with different network chain densities (¿) is studied. For the weakly vulcanized rubber, the melting stretching ratio ¿m at room temperature is the lowest. This ... -
Engineering polymers with improved charge transport properties from bithiophene-containing polyamides
(Royal Society of Chemistry (RSC), 2020)
Article
Open AccessPolymer semiconductors show unique combinations of mechanical and optoelectronic properties that strongly depend on their microstructure and morphology. Here, we have used a model p-conjugated bithiophene repeat unit to ... -
High-performance polyamides with engineered disorder
(2021)
Article
Open AccessThe extraordinary property profiles of many biological materials derive from their hierarchical structure and control of order and disorder at different length scales. Application of these concepts to the design of synthetic ... -
Influence of strain rate and temperature on the onset of strain induced crystallization in natural rubber
(Elsevier, 2015-03)
Article
Open AccessStrain induced crystallization (SIC) of natural rubber (NR) has been studied in a large range of strain rate (from 5.6 × 10-5 s-1 to 2.8 × 101 s-1) and temperature (from -40 °C to 80 °C) combining mechanical and thermal ... -
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 ... -
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. ... -
Temperature dependence of strain-induced crystallization in natural rubber: On the presence of different crystallite populations
(Elsevier, 2015-03)
Article
Open AccessThe effect of the temperature on strain induced crystallization (SIC) of natural rubber (NR) is studied by in situ wide angle X-rays scattering (WAXS) experiments performed along different thermo-mechanical paths (cyclic ...
