Synthesis of Hollow Silica Fibers with Porous Walls by Coaxial Electrospinning Method

Hollow Silica (SiO2) fibers with porous walls were synthesized by a coaxial electrospinning method. The SiO2 sol prepared by a sol–gel route was blended with polyvinylacetate to prepare precursor solutions for electrospinning. Electrospinning‐synthesized hollow SiO2 fibers were highly porous with po...

Zusammenfassung:Hollow Silica (SiO2) fibers with porous walls were synthesized by a coaxial electrospinning method. The SiO2 sol prepared by a sol–gel route was blended with polyvinylacetate to prepare precursor solutions for electrospinning. Electrospinning‐synthesized hollow SiO2 fibers were highly porous with pore diameters of ~45 nm. A slow heating rate
