Progress in preparation of nano-porous oxides by electrospinning

The principle of electrospinning technique for preparing porous oxides is briefly expounded, the material properties and preparation methods of several nano-porous oxides that are successfully prepared in recent years are simultaneously summarized and analyzed. The influence rule of electrospinning process parameters which consist of polymer, properties of electrospinning solution, applied voltage, electrode distance, liquid velocity and the condition on structure and morphology of porous oxides are summarized. The overseas and domestic research status of several years referring to filtering, individual protection, sensor, self-cleaning, catalytic carrier and other special fields and two kinds of new methods and technologies of electrospinning are also introduced. Finally, the developing direction and industrial prospect of electrospinning technique are analyzed and predicted.
