Studied for epikote-sodiam dihydrogen phosphate complex material of phase change energy storage

Storage energy by phase change have more advantage,for example,simplify craft,advantageous use, low price costing.It is a focal point in utilization of energy and temperature controlling of system.This study deals with a new preparation method for complex material of phase change storage.Results obtained from DSC and IR showed,that the complex material has more than one peak of phase change among the temperature blow 100℃,and the total latent heat of the complex material is more great.In the complex phase change material,the Na_2HPO_4·12H_2O was encapsulated with epikote.There are no chemical reactions that between the supporter of epikote and the unit of phase change material.
