Preparation of Polymer Capsules for Solid Hydrogen Storage

摘要：

　　Phase inversion of polymer solution by immersion-precipitation method was used to prepare porous hollow capsule – nickel boride composite.The composite was used as a carrier for sodium borohydride,in which sodium borohydride was absorbed into the capsules or embedded in the capsules during the processing of capsules formation.The preparation method and adsorption property of the polymer capsules were studied.The effect of capsules structure on the storage capacity of sodium borohydride was investigated.The results showed that capsules prepared by 18wt% of PVDF-DMF solution with adding 15% PVP had the best adsorption capacity.While capsules prepared by PVA had better affinity to water,this made them easier to absorb sodium borohydride in the aqueous solution.
