本文采用溶胶-凝胶法制备间苯二酚/SiO_2杂化溶胶,拉丝法制取杂化纤维.并采用FT-IR、DSC、TG、XRD和SEM对杂化纤维进行了表征.结果表明,杂化纤维中部分间苯二酚与SiO_2形成共价键结构;杂化纤维呈非晶态.采用不同温度对杂化纤维进行热处理,得到的产物经1300 ℃处理后杂化纤维转变为SiO_2/SiC结晶性多孔纤维.
SiO_2/Resorcinol hybrid sol was prepared by sol-gel method using TEOS and resorcinol as raw materials, and SiO_2/resorcinol hybrid fiber was prepared by drawing method. The hybrid fiber was characterized by FT-IR, DSC, TG, XRD and SEM. The results showed that partial resorcinol is linked silica with coralent bonds and the fiber was amorphous. The hybrid fiber was pyrolyzed at 600～1300 ℃ under atmosphere, the FT-IR, XRD and SEM showed that the hybrid fiber convert into porous SiO_2/SiC fiber when it was heated at 1300 ℃.
