EFFECT OF POLYACRYLONITRILE ON HYDROPHILICITY PROPERTIES AND THERMO-SENSITIVE OF HYDROXYPROPYLCELLULOSE

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.Results that the phase transition temperature and hydrophilicity of HPC all decreased with the addition of PAN can be seen from contact angle and SEM image of HPC/APN blend films.
