Background technology
Aerogel material mutually builds up by colloidal particle or high-polymer molecular a kind of nanoporous solid material with network structure formed, because its aperture (< 50nm) is less than the mean free path (~ 70nm) of air molecule, thus in aerogel pores, do not have convection of air, there is extremely low gaseous heat conduction; Aerogel has high porosity simultaneously, and shared by solid, volume ratio is very low, and solid state heat conduction is also very low.Carbon back aerogel resistance to elevated temperatures in various aerogel best (>=1600 DEG C), has in High Mach number aircraft thermal protection field the superiority that can not be substituted.But the insufficient strength of pure aerogel material, generally all needs strongthener such as fiber to improve its intensity.
Graphene is a kind of nano-carbon material of the two-dimentional laminated structure be made up of carbon atom, has high-specific surface area.The characteristic such as strong mechanical performance, high thermal conductivity.Present stage, graphene aerogel material (Chinese patent: CN101941693A) mainly through preparation graphene oxide water solution, then obtains through the process such as sol gel reaction, drying.Graphene aerogel prepared by this process is by graphene sheet layer build stack, and the graphene aerogel intensity prepared is high, but thermal conductivity is also high, can not directly use as lagging material.About the research of graphene aerogel mainly utilizes the strong mechanical performance of Graphene and high heat conductance to improve mechanical property and the thermal conductivity of gained aerogel material in prior art.Such as, CN201210191045.2 discloses a kind of method that constant pressure and dry prepares Graphene cross-linking type organic aerogel and charcoal-aero gel, and it mainly utilizes the strong mechanical performance of Graphene to solve the excessive problem of the shrinking percentage of the aerogel that constant pressure and dry obtains.Again such as, CN201310085977.3 provides a kind of graphene oxide/organic aerogel composite with low-shrinkage, wherein utilizes Graphene itself as framework material to provide the mechanical property of gained Graphene organic aerogel composite.Again such as, CN201310504175.1 discloses the preparation method providing a kind of graphene aerogel, the method is by graphene oxide water solution and polymkeric substance: the aqueous solution of tetrafluoroethylene, polyvinyl alcohol, polyvinylidene difluoride (PVDF) or Xylo-Mucine, by cohesive action, graphene oxide structural unit be connected with polymer unit physics and form graphene oxide colloidal sol, then obtain graphene aerogel by dry, reduction, make aerogel farthest can play the performances such as the excellent conduction of Graphene, heat conduction, mechanics thus.
But, also there is no the aerogel preparation method that can keep or reduce the thermal conductivity of aerogel material while improving Mechanical Properties of Aerogels at present.
Summary of the invention
The present inventor is found by research, although it is well known that, Graphene has high thermal conductivity, but when the lower thermal conductivity by aerogel can also be reduced when the combinationally using of Graphene and framework material while the intensity improving aerogel especially fortifying fibre composite aerogel.In other words, the use of framework material can reduce the thermal conductivity of graphene aerogel material.
So one object of the present invention is to overcome the high problem of existing graphene aerogel material thermal conductivity, provides a kind of preparation method of graphene aerogel material and graphene aerogel material obtained by this method.
In first aspect, the invention provides a kind of preparation method of graphene aerogel material, wherein, described method comprises the steps:
