NOVELTY - Encapsulating flexible phase change material by double network by two-step mixed normal temperature pressing method comprises (i) heating paraffin in an oil bath to make it into a molten state, then adding expanded graphite to mix and stir, and fully absorbing liquid paraffin by pores of expanded graphite, (ii) uniformly mixing natural latex liquid and graphene oxide dispersion, and cooling mixed material obtained in step (i) to room temperature, adding mixed solution of liquid natural latex and graphene oxide, fully stirring and mixing, making liquid natural latex fully adhere between pores of expanded graphite and paraffin, (iii) introducing mixed material obtained in step (ii) into mold, and hot pressing with pressure of 10-15 MPa at 40-60℃ to solidify natural latex, and (iv) collecting off pressed material from mold while it is hot. USE - The method is useful in encapsulating flexible phase change material by double network by two-step mixed normal temperature pressing method for thermal management fields i.e. fifth generation chips and lithium-ion batteries. ADVANTAGE - The material: has high thermal conductivity, high enthalpy, high resistance, good flexibility at room temperature, and enhanced wettability. The method: is simple; has high efficacy; solves problems of liquid leakage, poor mechanical properties and low thermal conductivity of traditional phase change materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for flexible phase change material, comprising 56-70 wt.% paraffin, 14-20 wt.% expanded graphite, 10-30 wt.% natural latex and 1-3 wt.% graphene oxide dispersion.
