摘　　要：The thermal decomposition kinetics of three inclusion complexes of βcyclodextrin with cholesterol,sebacic acid,and vanillin was studied by using non-isothermal thermogravimetry.Their average apparent activation energies of the thermal decomposition were obtained.The experimental result indicated that several weak interactions cooperatively contributed to the inclusion complexation of the βcyclodextrin hosts,and the complex thermal stability were dominated by the size/shape-matching between host and guest and hydrogen band interaction,however,the quantitative ratio do not obviously iv the complex thermal stability.The thermal decomposition kinetics of three inclusion complexes of βcyclodextrin with cholesterol,sebacic acid,and vanillin was studied by using non-isothermal thermogravimetry.Their average apparent activation energies of the thermal decomposition were obtained.The experimental result indicated that several weak interactions cooperatively contributed to the inclusion complexation of the βcyclodextrin hosts,and the complex thermal stability were dominated by the size/shape-matching between host and guest and hydrogen band interaction,however,the quantitative ratio do not obviously iv the complex thermal stability.
