功能性碳化硅先驱体聚铁碳硅烷的合成及熔融纺丝

Synthesis and Melt-spinning of Polyferrocarbosilane as a Functional Silicon Carbide Precursor

采用低分子量的聚硅烷(LPS)和二茂铁合成了聚铁碳硅烷(PFCS),探索了反应温度、裂解温度、二茂铁等因素对合成聚铁碳硅烷工艺的影响;研究了纺丝温度、收丝速率、压强对纤维平均直径的影响。

Polymerize a polyferrocarbosilane(PFCS) with low molecular weight polysilane and ferrocene and investigate synthesis technics including reaction temperature, pyrolysis temperature and ferrocene. Spinning temperature, pressure and spinning ratio affecting the diameter of fiber are studied.
