高温热处理PAN基CF时硼的促进石墨化作用

The Action Promoting Graphitization for Boron During the High Temperature Heat Treatment of PAN based Carbon Fiber

研究了热处理温度、H3BO3 溶液质量浓度和CF在H3BO3 溶液中的浸泡时间等因素对PAN基CF力学性能和电学性能的影响,并通过考察添加和未添加H3BO3 的CF分别经高温石墨化热处理后在结构和性能上的差异。

The influences of the heat treatment temperature,the boric acid solution concentration and the soaked time in boric acid solution on the mechanical and electrical properties of PAN based carbon fiber(CF) have been studied.The CF samples were prepared by adding or no boric acid high temperature heat treatment and their differences in structure and properties have been investigated.The action promoting graphitization for boron has been investigated too.
