The effect of processing conditions on the morphology, thermomechanical, dielectric, and piezoelectric properties of P(VDF-TrFE)/BaTiO3 composites
Véronique Michaud, Yves Leterrier, Dragan Damjanovic, Sara Dalle Vacche
In this study (0-3) P(VDF-TrFE)/BaTiO3 composites containing up to 60 vol% of ceramic phase were prepared by solvent casting or compression molding. Their thermomechanical, dielectric, and piezoelectric properties were investigated, and discussed in the li ...
Springer Verlag2012Immobilized polymer fraction in hyperbranched polymer/silica nanocomposite suspensions
Yves Leterrier, Sara Dalle Vacche, Valérie Geiser, Riccardo Ruggerone
The glass transition behavior of hyperbranched polymer (HBP) molecules with suspensions of silica and glass particles up to the concentrated regime (25 vol %) was analyzed by modulated differential scanning calorimetry (MDSC). The reversing and nonreversin ...
American Chemical Society2010Time-Intensity Superposition for Photoinitiated Polymerization of Fluorinated and Hyperbranched Acrylate Nanocomposites
Sara Dalle Vacche, Valérie Geiser
The validity of the time-intensity superposition principle for the photoinitiated polymerization of nanocomposites based on a monofunctional fluorinated acrylate and on a multifunctional hyperbranched polyether acrylate was investigated in this work. Maste ...
2010Morphology and mechanical properties of isotactic polypropylene glass mat thermoplastic composites modified with organophilic montmorillonite
John Christopher Plummer, Sara Dalle Vacche, Chrystèle Houphouet-Boigny Favre
Satisfactory impregnation of glass fiber mats may be obtained with isotactic polypropylene/montmorillonite (MMT) nanocomposites under conditions comparable with industrial conditions. However, it is demonstrated here that the high melt viscosity of the nan ...
Springer US2010The Effect Of Processing Conditions On The Morphology, Mechanical And Electrical Properties Of Batio3-Polymer Composites
Véronique Michaud, Yves Leterrier, Sara Dalle Vacche
Ferroelectric ceramic – polymer composites have a unique mix of electrical and mechanical properties. Piezoelectric and pyroelectric activity, a wide range of dielectric constants and high breakdown strength are combined with mechanical flexibility, formab ...
2010Hybrid Glass Mat-reinforced Polypropylene-Montmorillonite Nanocomposites
Véronique Michaud, John Christopher Plummer, Martyn Douglas Wakeman, Sara Dalle Vacche, Chrystèle Houphouet-Boigny Favre
Polypropylene/montmorillonite (iPP/MMT) has been investigated as an alternative to isotactic polypropylene (iPP) as a matrix for glass mat thermoplastic (GMT) composites. The melt viscosity increased significantly on MMT addition, but iPP/5.9wt% MMT-based ...

Véronique Michaud, John Christopher Plummer, Sara Dalle Vacche, Chrystèle Houphouet-Boigny Favre
Although addition of montmorillonite (MMT) clay to isotactic polypropylene (iPP) results in large increases in the melt viscosity at low shear rates, satisfactory impregnation of glass mats is obtained with iPP/MMT under conditions typical of industrial pr ...
