Description
Technical field
The invention belongs to the field of constructing of surface micro-nano structure, more particularly to a kind of side of constructing of graphenic surface fold
Method.
Background technology
Regulating microstructure based on macromolecule matrix surface is the great research topic in nano science field, particularly bullet
Elastomeric surface biomimetic features are constructed and regulated and controled.Researcher obtains inspiration from the surface microstructure in the Nature, in laboratory
Construct bionic surface fold.1998, Bowden et al. obtained the pleated structure of metallic film by the thermal contraction of substrate, opens
The new page of surface folding is constructed in laboratory（Nature 1998, 393: 146-149）.According to constructing surface folding forerunner
The difference of body, constructing mainly for surface folding has three kinds of strategies：（1）Surface folding based on the double-deck system of film/substrate is constructed；
（2）Surface folding based on gradation type substrate is constructed；（3）Surface folding based on homogeneity substrate is constructed（Prog. Polym.
Sci. 2015, 42: 1-41）.
Graphene is due to the uniqueness of itself structure, such as：The two dimensional crystal of the honeycomb of monoatomic layer thickness,
It is to have now been found that the Two Dimensional Free state crystal uniquely existed, and this causes it to have extremely excellent electricity, magnetics, catalysis, heat
Learn and the physical and chemical performance such as mechanics so that it have in new energy materialses, sensor and all kinds of field of compound material it is extremely wide
General application prospect.Graphene is built into wrinkled surface to assign its more excellent performance.Wang et al.（ACS Nano
2011, 5: 3645-3650）Preprepared graphene is transferred to the planar structure polydimethylsiloxanes for applying tension
In alkane flexible substrate, by the stress in release liners, graphene is set to recover the process of nature in dimethyl silicone polymer
Middle formation corrugated foldable structure, gained wrinkled surface has good stress response characteristic.
Although in constructing and its application field for the micro- fold of graphenic surface, having been achieved for preliminary achievement in research,
There is also some limitations and deficiency：On the one hand, worked and be mainly based upon the surface construction graphene fold of two-dimentional matrix, lacked
Weary real three-dimensional construction method, yet there are no the document report constructed based on hollow sphere and cylindrical base graphene fold
Road；On the other hand, Graphite During The Process alkene surface folding generally pre-stretching rate is constructed at present smaller, it is difficult to obtain height folded state,
Or need to obtain height folded state by multistep transfer, process is extremely cumbersome.Do not find also at present by disposable three-dimensional
Shrink and prepare the report that height folds graphene fold.
The content of the invention
