摘要
The thermal decomposition kinetics of three inclusion complexes of βcyclodextrin 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 βcyclodextrin hosts,and the complex thermal stability were dominated by the size/shape-matching between host and vip and hydrogen band interaction,however,the quantitative ratio do not obviously iv the complex thermal stability.
