Langues : Anglais (eng) Catégories : Alumine Antimoine dopé d'oxyde d'étain Charges (matériaux) Dépôt par pulvérisation Diamant Diisocyanates Diols Graphène Le 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.

It is widely used in many applications such as medical, automotive and industrial fields. It can be foundin products such as furniture, coatings, adhesives, construction materials, paints, elastomers, insulators, elastic fibers, foams, integral skins, etc. because it has extraordinary which are available. Though the material is having fascinating properties the material is also associated with various problems such as inferior coating properties. Inorganic pigments and fillers are dispersed in organic components and binders to coating systems. It gives general introduction about the various fillers and it's classification, mechanism by which the filler enhances the mechanical properties of the materials, various factors which affects the properties of the coatings. Various methods of incorporaton of fillers in the coating systems are discussed. Various nano fillers such as SiO2, TiO2, AL2O3, antimony doped tin oxide (ATO), BaSO4, FE2O3 as well as carbon nanotubes, graphene derived fillers and nano diamonds are discussed in detail. The importance and effect of surface modification of fillers to enhance coating properties is also discussed along with challenges associated with challenges associated with polyurethane coatings and future trends.
