摘要: The polymerization of styrene in the media of MCM-41 is carried out by means of host-guest
polymerization of styrene in MCM-41 mesoporoas material with the aim to investigate the
effects of interface and confinement of MCM-41 on host-guest interactions. Detailed
physical properties of the mesoporous MCM-41 material containing polystyrene is
characterized by XRD(X-ray diffraction), FT-IR(Fourier transform infrared), TGA(thermal
gravimetric analysis), and nitrogen adsorption-desorption isotherms. We also find a great
increase in the glass transition temperature of guest polystyrene influenced by the
confined geometry of the host by differential scanning calorimetry (DSC).
