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.

Abstract: Cross-linked poly(N-isopropylacrylamide) tethered Hydroxyapatite hybrid materials (HA- PNIPAM) were prepared by the ATRP reaction. The hybrid materials were characterized by FT-IR、TGA、SEM and UV spectra. The TGA results demonstrated that there was 122 g PNIPAM grafted on the surface of per 100g of HA. The UV results showed that the HA-PNIPAM have thermal responsive property around 33°C.
