| Ionic liquids and Metal-Organic Frameworks are new materials which have been the concern of the researchs at home and abroad.The use of them have been exploring increasingly.In this paper,a ionic liquid with dual functional imidazolyl and a ZIF-7 were prepared. Quantum-mechanical calculation was combined with experiment, and a new application field for phase change energy storage, absorption of CO2 is explored. This article has reported the preparation of [C4MIM]PF6,[C16MIM]PF6, and take them for core material. Melamine-formaldehyde resin as wall materials in-situ Polymerization of Microencapsulated Phase Change.Take ionic liquids as a core material of phase change microencapsulated materials have been exploring the synthesis.The stable configuration and the corresponding parameter of 44 kinds ionic liquids that are in the existing melting heat literature have been optimized with quantum chemistry semi-empirical PM3 method in this paper. The mathematics models of quantitative characterization structural parameter and melting heat were established, the result indicates that models are good enough to exactly be a predicted function and a good correlation.A determine has been made on the thermal properties of the melting and solidification process of ionic liquids by using differential scanning calorimeter (DSC).This paper has carried out a detailed experiment to find out the methods to synthesize ZIF-7 compound. We synthesize different samples in different conditions and analyse their structures by XRD. We have investigated how the crystallization time and crystallization concentration affect the ZIF crystalline compounds by changing single variable.The solubility of CO2 in DMC with ZIF-7 were measured.The result shows that the solubility of CO2 in DMC with 1.5wt% ZIF-7 increases while gas pressure rises and decreases while temperature rises. It indicates that ZIF-7 has potential for absorption of CO2.
