| Abstract |
| Micro-scale silicon carbide (SiC) fiber mat was produced by blowing of an oil-inwater
(O/W) precursor emulsion process combined with a thermal curing treatment
and a subsequent calcination at high temperature, which we named emulsion-blow
spinning (EBS). An air flow with high velocity was used to attenuate the O/W emulsion
jets, and the as-spun fibers can be successfully self-sustained to three-dimensional
network structure. Polycarbosilane micelles (precursor) entrapped in an aqueous
polyoxyethylene matrix resulted in SiC fibers with crystalline after pyrolysis and
ceramic process. The SiC fiber mat was tested with an excellent thermal stability and
semi-conductivity, may have potential applications on electronic and energy storage.
