摘要
Hydrophilic photoluminescent CdTe/poly （1, 4-butanediol-citrate） （PBC） bioelastomer nanocomposite was successfully synthesized by a two-step method and characterized by X-ray diffraction （XRD）, Fourier trans- form infrared （FT-IR） spectroscopy, Uv-vis spectroscopy, photoluminescence （PL） spectroscopy and scanning elec- tron microscope （SEM）. The differential scanning calori- metry analysis shows that the bioelastomer nanocom- posites with different mass fractions of CdTe have low glass-transition temperature, which indicates that they possess elastic property in the range from room tempera- ture to the expected applied temperature （37℃）. The measurements of the hydrophilicity, in vitro degradation and PL show that the nanocomposite has good hydro- philicity, degradation and high fluorescence properties.
