Abstract: Provided herein are methods for forming nanofibers. The current disclosure provides ceramic nanofibers, morphology-controlled ceramic-polymer hybrid nanofibers, morphology-controlled ceramic nanofibers, core-sheath nanofibers and hollow core nanofibers using ceramic precursor materials and polymer materials which are combined and undergo electrospinning. The current disclosure provides for methods of forming these nanofibers at low temperatures such as room temperature and in the presence of oxygen and moisture wherein the ceramic precursor cures to a ceramic material during the electrospinning process. Also disclosed are the nanofibers prepared by the disclosed methods.
