Preparation of polyvinylpyrrolidone (PVP) nanofibers supported CaCO_3 nanoparticles

摘要

In this paper, a new method for the preparation of composite nanofibers surface containing calcium carbonate nanoparticles using electrospinning technology was described. In detail, firstly, the type solution is formed by the aqueous solution of CaCl_2 which contains polyvinylpyrrolidone (PVP) and the other is the aqueous solution of K_2CO_3. Two types of solution were mixed completely, and then Ca~(2+) and CO_3~(2-) generated CaCO_3 nanoparticles. Secondly, composite nanofibers with CaCO_3 nanoparticles were successfully prepared by above solution electrospun. The resulting composite nanofibers were characterized by field-emission scanning electron microscopy (FE-SEM), it determination showed that perfect mono-dispersed spherical CaCO_3 nanoparticles were dispersed on polyvinylpyrrolidone (PVP) nanofibers.
