Fabrication and morphological study of converged <i>SiC</i>-TiC fiber mats by electrospinning

Abstract

Titanium-containing silicon carbide (SiC) fiber mats were fabricated by an electrospinning method followed with a polymer-derived ceramics route. Titanium isopropoxide was used to cross-link into polycarbosilane (PCS) in toluene and xylene contained in the medium. The mat structure, fiber morphology, and crystallization of the fabricated SiC fibrous mat were analyzed by scanning electron microscopy and X-ray diffraction. According to the analysis results, the ceramic yield of the precursor increased significantly because of the high degree of cross-linking in PCS molecular structure.
