英文摘要	National Natural Science Foundation of China [50532010]; Fujian Key Laboratory of Advanced Materials, China [2006L2003]; A hybrid polymer as the precursor for TiO2/SiO2 composite fibers was prepared by blending polycarbosilane (PCS) and tetrabutyl titanate, named as PCST, which contains unreacted organic tetrabutyl titanate compound. The PCST was characterized by FT-IR, TGA and NMR (H-1, C-13 and Si-29). The results showed that the PCST could be described as a part dispersion of Ti(OC4H9)(4) groups in the PCS chain matrix. The TiO2/SiO2 composite fibers were manufactured by melt-spinning PCST, maturing and curing the resulting fibers in air, followed by a final pyrolysis at 1200 degrees C in air. Based on the XRD, EPMA, EDS, SEM and HRTEM measurements, the TiO2/SiO2 fibers were made up of anatase-TiO2 nanocrystallites with a mean size of similar to 10 nm and in the amorphous silica phase.
