Abstract:
(EN) A graphene composite material and a preparation method therefor. By adding a pleated spherical graphene oxide and a catalyst to a precursor, the pleated spherical graphene oxide is highly dispersed and gradually dissociated into single-layer graphene oxide sheets while a polycondensation reaction occurs, some esterified molecules can react with the hydroxyl group and carboxyl group on the surface of the graphene oxide sheets to form chemical bonds, and at the same time, the graphene oxide is thermally reduced, and finally a composite material composed of PET and graphene sheets grafted with PET on the surface is obtained. The present invention avoids the stacking of graphene oxide in the esterification stage, greatly saving costs and increasing the production efficiency. The graphene obtained has a good dispersibility in a polymer matrix, and the formation of the covalent bond between the two materials effectively increases the properties of the system such as the mechanical properties, electrical conductivity properties, and the like. The involved preparation method is simple and effective, and thus can effectively save costs. The composite material obtained has superior properties, and can be used to prepare a high-performance dacron fabric.
(FR) La présente invention concerne un matériau composite à base de graphène et un procédé de préparation associé. Par l'addition d'un oxyde de graphène sphérique plissé et d'un catalyseur à un précurseur, l'oxyde de graphène sphérique plissé est hautement dispersé et progressivement dissocié en feuilles d'oxyde de graphène monocouches tandis qu'une réaction de polycondensation se produit, certaines molécules estérifiées peuvent réagir avec le groupe hydroxyle et le groupe carboxyle sur la surface des feuilles d'oxyde de graphène pour former des liaisons chimiques et, en même temps, l'oxyde de graphène est thermiquement réduit et, enfin, un matériau composite composé de PET et de feuilles de graphène greffées par du PET sur la surface est obtenu. La présente invention évite l'empilement d'oxyde de graphène dans l'étape d'estérification, ce qui économise considérablement les coûts et augmente considérablement l'efficacité de production. Le graphène obtenu présente une bonne dispersibilité dans une matrice polymère et la formation de la liaison covalente entre les deux matériaux augmente efficacement les propriétés du système, telles que les propriétés mécaniques, les propriétés de conductivité électrique et similaires. Le procédé de préparation mis en jeu est simple et efficace et permet ainsi d'économiser efficacement les coûts. Le matériau composite obtenu présente des propriétés supérieures et peut être utilisé pour préparer un tissu dacron à haute performance.
(ZH) 一种石墨烯复合材料及其制备方法,通过在前驱体中加入褶球状氧化石墨烯和催化剂,在发生缩聚反应的同时,褶球状氧化石墨烯高度分散,并逐步解离为单层氧化石墨烯片,部分酯化分子可与氧化石墨烯片表面的羟基、羧基反应形成化学键,同时使氧化石墨烯发生热还原,最终得到由PET和表面接枝有PET的石墨烯片组成的复合材料。避免了酯化阶段中氧化石墨烯的堆叠,大大节约了成本,提高了生产效率。所得石墨烯在聚合物基体中分散性好,并且两种材料之间共价键的形成有效提高体系的力学性能、电导率等性能。所涉及制备工艺简单有效,可有效节约成本,所得复合材料性能优越,并可用于制备高性能涤纶织物。
