Electronspun Thermal Responsive and Photocatalytic Zn(NO3)2/PNIPAAm Nanofibers

Article Preview

Abstract:

Zn (NO3)2/PNIPAAm fibrous films were fabricated via electrospinning method, and then the morphologies of the films were investigated by high resolution scanning electron microscopy (SEM). The diameters and the alignment of fibers were analyzed using Image J software. The functional groups within the nanofibers were analyzed using Fourier Transform Infrared Spectroscopy (FTIR). The thermal responsive properties of the hybrid films were investigated using contact angle (CA) measurement method. Photocatalytic efficient activities were evaluated by degradation of methylene blue (MB) under 100W UV light at room temperature.
