VernisIndex. décimale : 667.9 Revêtements et enduits Résumé : Newly synthesized polycarbonate diols containing hindered urea (PCD-HUs) were employed to modify the scratch-healing properties of conventional two-component clearcoats. To elucidate their contributions to the crosslinking properties of the coatings under conventional thermal curing (150°C), the real-time rheological properties of the clearcoat mixtures were measured using a rotational rheometer in the small-amplitude oscillatory shear mode. A dynamic mechanical analysis was carried out to compare the thermomechanical properties of the cured clearcoat free films. PCD-HU, a key component for the tuning of the scratch-healing, was further identified by analyzing the clearcoat layer cured over a phosphated metal substrate with undercoats such as primer and basecoat as a precoated metal (PCM) sheet. Elastic recovery and scratch profiles of the outermost clearcoat layer in the PCM sheet were acquired through nano-indentation and nano-scratch tests by gradually increasing the quantitative normal force. Finally, the healing patterns of the scratches on various clearcoat layers at a certain normal force were visualized by three-dimensional and one-dimensional cross-cut images using atomic force microscopy under specified temperature and healing time conditions. The surface durability provided by the PCD-HU in the clearcoat layer was confirmed by repeated scratching and healing tests on the same surface positions. Therefore, the coating layer containing HU, which possessed similar surface mechanical properties to those of conventional references, exhibited better scratch-healing performance.

ThermodurcissablesIndex. décimale : 668.4 Plastiques, vinyles Résumé : A series of bio-based hybrid thermosets composed of maleinated acrylated epoxidized palm oil (MAEPO) and vinyl ester resin (VE) were produced using free radical-induced crosslinking. The amount of petroleum-based resin which was replaced by bio-resin (MAEPO) was varied from 5 to 20 wt%. The structure of the polymer systems was investigated by scanning electron microscopy and dynamic mechanical analysis. The mechanical properties of the VE/MAEPO resins were studied using tensile, flexural and impact tests. The result obtained from structural analysis revealed that for the polymer hybrids with up to 20 wt% bio-resin content, there is good compatibility between MAEPO and VE as no phase separation was observed for these systems. The prepared eco-friendly bio-based thermosetting resins exhibit remarkable improvement in toughness parameters, such as ductility and impact strength, thereby showing potential for use in composites and nanocomposites applications.

GraphèneLe graphène est un cristal bidimensionnel (monoplan) de carbone dont l'empilement constitue le graphite. Il a été isolé en 2004 par Andre Geim, du département de physique de l'université de Manchester, qui a reçu pour cette découverte le prix Nobel de physique en 2010 avec Konstantin Novoselov. Il peut être produit de deux manières : par extraction mécanique du graphite (graphène exfolié) dont la technique a été mise au point en 2004, ou par chauffage d'un cristal de carbure de silicium, qui permet la libération des atomes de silicium (graphène epitaxié). Record en conduction thermique jusqu'à 5300 W.m-1.K-1. C'est aussi un matériaux conducteur.
