Design and fabrication of compositionally graded inorganic oxide thin films: Mechanical, optical and permeation characteristics

Yves Leterrier, Xavier Bulliard, Ji Hyun Kim

Different types of inorganic oxide films composed of a chemical composition gradient single layer were designed, fabricated and characterized. Compositionally graded thin films were created by power-controlled co-sputtering of alumina (Al2O3) and silica (S ...

Effect of HBP modified γ-APS on the coating toughness and practical adhesion between galvanised steel and polyethylene

Véronique Michaud, Xavier Bulliard, Gabrielle Pax

Epoxy-functionalised hyperbranched polymers (HBP) were combined with aminosilanes to form coatings and their effect on the practical adhesion between galvanised steel and polyethylene was investigated. It was shown that HBPs were initially soluble in silan ...

Low-Profile mechanisms in a PVAc/polyester blend

Véronique Michaud, Xavier Bulliard

The different steps associated with the curing of a PVAc/polyester blend are identified and correlated to the mechanism of shrinkage control in the presence of a low-profile additive (LPA). Poly(vinyl acetate) (PVAc) is used as a LPA and is shown to induce ...

Reaction-Induced Phase Separation in Poly(vinyl acetate)/ Polyester Blend

Véronique Michaud, Xavier Bulliard

In blends of unsaturated polyester (UP), poly (vinyl acetate) (PVAc), and styrene, a reaction-induced phase separation occurs upon curing that is due to the crosslinking between styrene and the UP molecules. The evolution of the morphology was observed by ...

Reaction-induced phase separation in a PVAc/polyester blend

Véronique Michaud, Xavier Bulliard

2006

The evolution of morphology of reactive thermoplastic/unsaturated polyester blends at the surface of glass fibers is investigated during curing. The study focuses on two different types of thermoplastics, incompatible and compatible respectively with the p ...

2005

A study of the microstructure developing at the surface of glass fibers in a poly(vinyl acetate) (PVAc)/polyester blend is presented. Three different experimental methods are used: a technique based on the Wilhelmy method to measure the wettability of the ...
