摘　　要：上浆是碳纤维及其复合材料开发与应用中必不可少的关键技术之一。随着先进聚合物基碳纤维复合材料的开发与应用,碳纤维上浆剂耐高温性能不足的问题日益凸显。本文综述了近年来碳纤维耐高温型上浆剂的研究进展,重点阐述了其水性化改性方法,并对各类上浆剂的表面性能、耐高温性能以及对复合材料力学性能的影响进行了分析。从产业化应用的角度,提出了碳纤维上浆剂不仅要对水溶性和耐热性等热点性能以及原材料与制备方法进行研究,更应当注重对碳纤维上浆剂整体应用性能的研究,如上浆剂乳液的稳定性、润湿性、粒径分布,上浆后碳纤维及复合材料的表界面性能和整体力学性能等。In the preparation process of carbon fibers,sizing is an indispensable process,and its function is to form a uniform thin layer of organic polymer on the surface of carbon fiber,protect the surface activity of carbon fibers,enhance the wettability,reactivity,adhesion and the like of carbon fiber surface.It is conducive to improving the bonding performance between fiber and resin matrix,and enhancing the comprehensive performance of composite products.The sizing agent is generally composed of the main body of polymer resin,and various surfactants and additives.Sizing agents are mainly divided into three categories:solvent-based sizing agent,emulsion-type sizing agent and water-soluble sizing agent,among which the water-soluble sizing agent has become the mainstream of carbon fibers and research and development of composite material thereof because of its storage stability,good safety and low environmental pollution.In recent years,China's carbon fiber industry has shown explosive development,and the development and application of polymer-based carbon fiber composites in frontier fields such as aerospace,high-speed rail,new energy vehicles and fuel cells have developed rapidly,which has put forward higher requirements for the development of high-performance carbon fiber composites.The decomposition temperature of the conventional sizing agent is about 200℃,and it is easy to be thermally decomposed under the conditions of high-temperature processing and molding process of high-temperature resistant and high-performance resin,resulting in local defects in the interface layer of the material and affecting the overall performance of the composite material.In order not to affect the high-temperature resistance of the composite material,it is necessary to develop a high-temperature resistant sizing agent that matches the high-temperature resistance of the resin matrix.Based on the relevant literature in recent years,it can be seen that the high-temperature resistance of the sizing agent is mainly achieved by the high-t
