Abstract
Hollow Silica (SiO 2) fibers with porous walls were synthesized by a coaxial electrospinning method. The SiO 2sol prepared by a sol-gel route was blended with polyvinylacetate to prepare precursor solutions for electrospinning. Electrospinning-synthesized hollow SiO 2fibers were highly porous with pore diameters of ∼45 nm. A slow heating rate <5°C/min during calcination was required to sustain the hollow and porous morphology. In addition, aligned hollow SiO 2fibers were successfully synthesized using a separate electrode configuration.
