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 ...

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 ...

Strain-induced network chains damage in carbon black filled EPDM

Nicolas Candau, Oguzhan Oguz

This paper presents an experimental method to follow in-situ the chains network alteration of filled vulcanized rubbers induced by deformation. Macroscopic damage is first investigated on a series of EPDM by quantifying void fraction via Digital Image Corr ...

Effect of surface modification of colloidal silica nanoparticles on the rigid amorphous fraction and mechanical properties of amorphous polyurethane-urea-silica nanocomposites

John Christopher Plummer, Nicolas Candau, Oguzhan Oguz, Stéphane Henri Florian Bernhard

Colloidal silica nanoparticles (NPs) modified with eight different silane coupling agents were incorporated into an amorphous poly(tetramethylene oxide)-based polyurethane-urea copolymer matrix at a concentration of 10 wt % (4.4 vol %) in order to investig ...
