摘　　要：不同的原料和方法所制备的泡沫炭结构和性能也有所不同,本文阐述了以石油系、萘系和煤沥青为原料制备中间相沥青基泡沫炭的制备工艺以及常用的改性方法。指出泡沫炭主要有五边形十二面体和球形气孔状两种结构,具有密度小、强度高、良好的导电和导热等优异性能,并展望了泡沫炭的应用及发展方向。The structures and properties of carbon foams vary greatly in terms of the raw materials used and the preparation methods adopted. In this paper, the preparation and commonly used modification methods of mesophase pitch- based carbon foams were described. Reticulated vitreous structure and Spherical cellular structure of carbon foams were pointed out. There are many superior properties of carbon foams, such as low density, high strength, high conductivity and high thermal conductivity. More- over, the potential application and direction of mesophase pitch- based carbon foams were predicted.
