Mesoporous Nano-bio-glass fiber Synthesis with High Surface area by Electrospinning

In this study، the synthesis of hollow nano-bio-glass fibers with Polyvinylpyrrolidone polymers were developed using electrospinning. Firstly، the ceramic sol in SiO2-CaO-P2O5-TiO2 system was prepared and stabilized. Then، the resulted sol was added to the polymeric solution. The final solutions with different viscosity were sent for the coaxial electrospinning under voltages of 10، 15، 20، and 25 kV. The morphology study of the electrospun fibers using SEM showed tolerable sizes for the samples and optimum conditions such as amount of Polyvinylpyrrolidone polymer and also the applied voltage were defined to reach hollow nano-bio-glass fibers with the high surface area. Regarding the obtained results، severals analysis such as STA، XRD، FTIR، and BET were developed on the optimized samples. Finally، The surface area results demonstrated that this nano-bio-glass fibers could be a good candidate as drug delivery system.
