| 제목 | Ultarfine TiO2 Fibers Electrospun from a Titanium Alkoxide Precursor Solution without Organic Polymer Additive |
| 초록 | In recent years, titanium oxide(TiO2) was widely studied in optical and electrical applications, such as photocatalysis, gas sensors and dye-sensitized solar cell and batteries. It is also very attractive as a biocompatible protective coating on medical implants, where a protective surface layer of TiO2 considerably increases the wear resistance and hardness. In order to increase its surface area, titania has been fabricated into nanostructures, such as nanoparticles, films and nanofibers, by various methods. Particularly, nanofibrous structures exhibit high surface area-to-volume and length-to-diameter ratios. Electrospinning has been widely studied because of its efficiency and simplicity for the production of fibrous structures with micro- to nanoscale. This technique is well established for producing polymer nanofibers. Recently, the electrospinning technique, in combination with sol-gel process, has been used to fabricate ceramic and metal oxide nanofibers, which are particularly useful for high temperature applications. Most of previous works for metal oxide nanofibers has focused on the electrospinning from a metal precursor solution mixed with organic polymer (binder and gelator), such as poly(vinyl alcohol) (PVA), poly(vinyl pyrrolidone) (PVP), poly(vinyl acetate) (PVAc), poly(ethylene oxide), etc. In this work, we prepared ultarfine TiO2 fibers from only a titanium alkoxide precursor solution without organic polymer additive.
