Mechanical reinforcement and memory effect of strain-induced soft segment crystals in thermoplastic polyurethane-urea elastomers

Nicolas Candau, Oguzhan Oguz, Adrien Julien Demongeot

An amorphous poly(urethane-urea) copolymer composed of 70 wt% poly(ethylene oxide) (PEO) soft segments (SS) (Mw = 2000 g mol−1) and 30 wt% cycloaliphatic hard segments (HS) was subjected to in-situ X-Rays during tensile deformation. Mechanical hardening at ...

Strain and filler ratio transitions from chains network to filler network damage in EPDM during single and cyclic loadings

Nicolas Candau, Oguzhan Oguz

Chains and filler network damage were investigated during single and multiple cycles on a series of vulcanized EPDM containing various filler contents. In both series of experiments, a strain and a filler ratio transitions for damage mechanisms were identi ...

Engineering polymers with improved charge transport properties from bithiophene-containing polyamides

Rosario Scopelliti, John Christopher Plummer, Farzaneh Fadaei Tirani, Holger Frauenrath, Nicolas Candau, Bilal Özen

Polymer semiconductors show unique combinations of mechanical and optoelectronic properties that strongly depend on their microstructure and morphology. Here, we have used a model pi-conjugated bithiophene repeat unit to incorporate optoelectronic function ...

Heat source and voiding signatures of Mullins damage in filled EPDM

Nicolas Candau, Oguzhan Oguz

The thermomechanical coupling of Mullins damage in filled EPDM has been investigated by analysing the self-heating via Infrared thermography (IR) and the voiding fraction by Digital Image Correlation (DIC). The volumetric strain measured during the rubber ...

A Sustainable Approach to Produce Stiff, Super-Tough, and Heat-Resistant Poly(lactic acid)-Based Green Materials

Nicolas Candau, Oguzhan Oguz, Mehmet Kerem Citak, Fatma Nalan Cetin

Circumventing inherent embrittlement, poor heat resistance, and melt elasticity of poly(lactic acid) (PLA) without compromising its remarkable stiffness and strength has become a particular challenge in polymer science due to increasing demand for green ma ...
