Description

A kind of large area zero defect two-dimensional colloidal monocrystalline, its preparation method and its transfer method
Invention field
The present invention relates to a kind of large area zero defect two-dimensional colloidal monocrystalline, the preparation that further relates to include this colloid monocrystalline and Its unperturbed transfer method.
Background of invention
Two-dimensional colloidal crystalline substance is widely used in the structure of various ordered structures as template because of its unique cycle regularity Build.For being built based on the brilliant ordered structure for template of two-dimensional colloidal, first have to solve the problems, such as be how to prepare large area Flawless two-dimensional colloidal is brilliant.So far, various methods have been developed to prepare two-dimensional colloidal crystalline substance in people, wherein Self-assembling technique most commonly based on convection current sedimentation.Existing document report, by this technology, in special Wedge device The lower flawless two-dimensional colloidal monocrystalline that can prepare Centimeter Level of auxiliary.But this method quite expends the time(Generally exist It is more than half an hour)And substrate surface hydrophilic and hydrophobic is required, once formation can not in smooth substrate for colloid monocrystalline in addition Shifted to other substrates.
Self-assembling technique, the two-dimentional glue being self-assembly of based on capillary force at water/gas interface are settled compared to convection current Body crystalline substance is gradually favored because of its convenient transferability by people.When colloidal particle suspension is added dropwise to water surface, hang Supernatant liquid can be sprawled rapidly in the water surface, while drive colloidal particle to do corresponding motion in the water surface.Under capillary force effect, colloid grains Son attracts each other and is finally paved with whole water/gas interface.By this method during Colloidal crystals are prepared, colloidal particle from Assembly behavior is uncontrolled, and the dislocation between colloidal particle can introduce substantial amounts of internal stress in Colloidal crystals, eventually tend to be formed Polycrystalline structure.Under normal circumstances, the area of individual domain arrives thousands of square microns between hundreds of.We have found in experimentation, Outfield is introduced during preparing two-dimensional colloidal crystalline substance at water/gas interface(Air-flow)Drive colloidal particle can in water/gas Interface Motion Effectively eliminate because colloidal particle dislocation and caused by internal stress.Adjusted by introducing emulsifying agent in aqueous phase between colloidal particle Capillary force size, and be aided with air-flow to promote the release of stress, finally can prepare large area at water/gas interface (10cm2Left and right)Do not have defective two-dimensional colloidal monocrystalline.
In principle, the two-dimensional colloidal crystalline substance prepared at water/gas interface can be realized by czochralski method to different base surface Transfer, but this transfer method can introduce water membrane between substrate and two-dimensional colloidal crystalline substance, and in the brilliant preparation of two-dimensional colloidal During the colloidal particle that is submerged in aqueous phase can also be introduced.After water volatilization, the colloidal particle that these are introduced into is just The position of original colloidal particle in two-dimensional colloidal crystalline substance can be substituted, and the colloidal particle that these positions are substituted then is randomly distributed in two Tie up Colloidal crystals surface.Said on stricti jurise, in substrate surface be not now that two-dimensional colloidal truly is brilliant.In order to Solves this problem, we are also improved the branch mode of Colloidal crystals.In our improved Colloidal crystals unperturbed transfer sides In formula, substrate is close to wall in a manner of near vertical.After large-area two-dimensional colloid single crystal preparation is good, by being added dropwise along wall The aqueous solution causes the connection in other three faces of colloid monocrystalline and wall to be blocked, colloid list after aqueous phase is siphoned off from container It is brilliant just spontaneously to be deposited under capillary forces to wall, so as to realize the transfer on basad surface.Because in transfer process, Substrate is approximately perpendicular to the water surface, so the formation of moisture film can be effectively prevented from, and then avoids two-dimensional colloidal single-crystal surface from freely dividing The formation of the colloidal particle of cloth.In addition, improved Colloidal crystals branch mode is a spontaneous process, can be effectively prevented from using lifting Disturbance of the human factor to colloid monocrystalline during method so that this transfer method has reliable repeatability.
Under said flow booster action the self assembly of water/gas interface prepare two-dimensional colloidal monocrystalline size up to 10cm2It is left Right and without any defect, preparation method is easy to operate, and the colloidal particle of different grains is applicable;Improved unperturbed branch mode The transfer to different base surface in the case where not producing obvious disturbance to colloid monocrystalline can be realized.
