Description
Technical field
The invention belongs to technical field of phase change energy storage, be specifically related to a kind of Graphene/paraffin composite phase change energy storage material and preparation method.
Background technology
Thermal energy storage technology, for solving the contradiction between heat energy supply and demand, is improve the utilising efficiency of the energy and the important technology of protection of the environment.In the energy-saving field of Solar use, " peak load shifting " of electric power, used heat and remaining pick up the heat and industry and civil building heating and air-conditioning, there is good application prospect.Phase-change accumulation energy is that the sensible heat of medium is first stored in phase change material, phase change material is undergone phase transition, the energy obtained is stored in phase change material with the form of latent heat, when needs energy, phase change material undergoes phase transition again, the latent heat stored is discharged with the form of sensible heat, completes a thermal energy exchange.
The more heat accumulating phase change material of current research is the organic solid-liquid phase change material of inorganic crystal salt hydrate, paraffin and fatty acid and the solid-solid phase transition material such as polyvalent alcohol, high density polyethylene(HDPE).Crystalline hydrate salt has larger Heat of fusion and volume storage density, but have serious mistake cold and separate out phenomenon; The great advantage of solid-solid phase transition material is that phase in version does not generate liquid state, and during transformation, volume change is little, but Gu more than solid-transition temperature time, they change plastic solid into by crystalline solid, and plastic solid has very high solid vapour pressure, volatile loss.Paraffin class phase change heat storage material is owing to having higher crossing latent heat, and nothing is crossed cold and separated out phenomenon, stable performance,
Nontoxic, non-corrosiveness, the advantages such as low price, but the main drawback of paraffin phase change material is exactly that thermal conductivity is very low, and the thermal conductivity of paraffin is only 0.150W/ (m DEG C), identical with the thermal conductivity order of magnitude of general lagging material, therefore conducts heat extremely slow.Usually adopt in actual applications add in olefin material high thermal conductivity material as copper powder, aluminium powder or graphite etc. as weighting material to improve thermal conductivity; Adopt finned tube heat exchanger, rely on the increase of heat interchanging area to improve heat transfer property.The heat storage capacity so both reducing organic phase change material turn increases preparation cost.
Graphene-structured is highly stable, and up to now, investigator does not find the situation having carbon atom to lack in Graphene yet.Connection in Graphene between each carbon atom is very pliable and tough, and when applying external mechanical force, carbon atom face with regard to flexural deformation, thus makes carbon atom need not rearrange to adapt to external force, also just maintains Stability Analysis of Structures.This stable crystalline network makes carbon atom have outstanding electroconductibility.When electronics in Graphene moves in track, or foreign atom can not be introduced and scattering occurs because of lattice imperfection.Because interatomic force is very strong, at normal temperatures, even if around carbon atom telescopes, the interference that in Graphene, electronics is subject to is also very little, and meanwhile, Graphene is the thinnest in the world is also the hardest nano material, it is almost completely transparent, only absorbs the light of 2.3%; Thermal conductivity is up to 5300 W/(mK), higher than carbon nanotube and diamond, under normal temperature, its electronic mobility is more than 15 000 cm2/(Vs), again than CNT (carbon nano-tube) or silicon wafer height, and resistivity only about 10-6 Ω cm, than copper or silver lower, be the material that world resistivity is minimum.Because its resistivity is extremely low, the speed that electronics runs is exceedingly fast, and Graphene is electroconductibility best material in the world, and electronics movement velocity wherein reaches 1/300 of the light velocity, considerably beyond the movement velocity of electronics in general conductor.
Graphene and paraffin have good avidity, and adulterate certain Graphene in paraffin, form a kind of new Graphene/paraffin phase change material, are the good solutions solving current wax phase change energy storage problem.
