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 ...

Poly(lactide)/cellulose nanocrystal nanocomposites by high-shear mixing

Véronique Michaud, Nicolas Candau, Oguzhan Oguz, Adrien Julien Demongeot, Mehmet Kerem Citak, Fatma Nalan Cetin

There is currently considerable interest in developing stiff, strong, tough, and heat resistant poly(lactide) (PLA) based materials with improved melt elasticity in response to the increasing demand for sustainable plastics. However, simultaneous optimizat ...

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 ...

Looping probabilities of elastic chains: A path integral approach

John Maddocks, Ludovica Cotta-Ramusino

We consider an elastic chain at thermodynamic equilibrium with a heat bath, and derive an approximation to the probability density function, or pdf, governing the relative location and orientation of the two ends of the chain. Our motivation is to exploit ...

Nanohydroxyapatite/poly(ester urethane) scaffold for bone tissue engineering

Pierre-Etienne Bourban, Carole Boissard

Biodegradable viscoelastic poly(ester urethane)-based scaffolds show great promise for tissue engineering. In this study, the preparation of hydroxyapatite nanoparticles (nHA)/poly(ester urethane) composite scaffolds using a salt-leaching-phase inverse pro ...

Synthesis of uniform, non-natural oligomers

Harm-Anton Klok, Nadja Franz

Oligomers with well-defined chain lengths are of interest as foldamers, are important as model compounds for high-molecular-weight polymers and find application in electrooptic and sensory devices. This account presents an overview of the strategies that a ...

Rheological Properties of Hyperbranched Polymer/Poly(ethylene Terephthalate) Reactive Blends

Yves Leterrier

The rheological properties in solution, in shear and in uniaxial elongation of poly(ethylene terephthalate) (PET) reacted together with hyperbranched polymers (HBPs) were investigated. Two different PET grades, of low and high molecular weights, were compo ...

An evolving system for simulating clothes on virtual actors

Daniel Thalmann

This cloth modeling and animation system aims to support virtual actors who can dress and undress themselves. It now creates autonomous clothes, independent of the synthetic human wearing them. The interactive editor, proportion box and body-scaling featur ...
