Green Synthesize the Hybrid Composite of Polyurethane/TiO_2

采用无毒、无害的绿色方法合成聚氨酯,通过掺杂法制备出一种新型的聚氨酯/纳米TiO2杂化材料。利用傅里叶变换红外光谱分析(FTIR)、差示扫描量热分析方法(DSC)分别对聚氨酯/纳米TiO2杂化前后的结构进行表征。通过循环伏安法检测表明此材料有良好的电化学稳定性及可逆性。通过荧光技术证明其光学性。为利用荧光技术研究杂化材料的结构及结构与性能的关系。

The manuscript reported a novel polyurethane/nano-TiO2 hybrid composite was prepared by directly mixing them together, it has been proven to a pollution free method for polyurethane synthesize. Then the physical and chemical and structural characterization were compared through Fourier Transform Infrared spectroscopy （FTIR）, and Differertial Scanning Calorimetry （DSC）, and the result of DSC confirmed that the heat stability of the component was improved. The electrochemical properties are examined by Cyclic Voltammetry（CV）, It also exhibits quite repeatable properties , better electrochemical stability and electroactivity in alkaleseence. Furthermore, this nano-hybrid component exhibited optical properties by fluorescence spectroscopy.
