Nanowerk  May 9, 2024 Electrospinning has been applied to produce ceramic fibers using sol gel-based spinning solutions consisting of ceramic precursors, a solvent, and a polymer to control the viscosity of the solution. However, the addition of polymers to the spinning solution makes the process more complex, increases the processing time, and results in porous mechanically weak ceramic fibers. Researchers in the UK developed a coelectrospinning technique, where a nonspinnable sol consisting of only the ceramic precursor(s) and solvent(s) was encapsulated inside a polymeric shell, forming core–shell precursor fibers that were further calcined into ceramic fibers with reduced porosity, decreased […]
