Effect of HPC on the Thermo-Sensitive and Hydrophilicity of PAN Films
In this paper, a series of blending films were prepared based on Polyacrylonitrile (PAN) and hydroxypropylcellulose (HPC). The phase transition temperature of these blend films was investigated by warming UV-vis spectrophotometer and Differential Thermal Scanning Calorimetry (DSC). The results showed that the phase transition temperature of HPC/PAN blend films was lower than that of HPC when adding PAN into HPC and the more PAN contents the lower LCST of blend films. The contact angle and surface image of HPC/APN blend films were studied. It was indicated that HPC could endow PAN film with not only thermo-sensitive property but also great hydrophilicity.
