Description
Technical field
The present invention relates to one of self-assembled film technical field montmorillonite self assembly film forming, and are deposited on the surface of solids
Method.
Background technique
Over the last couple of decades, the researchers of every country pass through deep exploration, it was found that a variety of ultrathin membranes
Preparation method.Especially in this field of LBL self-assembly, there is significant progress, this is because this method of LBL self-assembly
It is upper with extraordinary effect in the innovative design and application of the ultrathin membrane with specific function property.By the hair of many years
Exhibition, layer-by-layer have become to gradually mature.
The development of self-assembled film technology mainly experienced three phases, i.e. Langmuir-Blodgett (LB) membrane technology, change
Learn absorption self-assembling technique and Electrostatic Absorption self-assembling technique.LB film is will be dispersed in solution not using special device
Molten object is transferred on solid support according to certain arrangement mode, to form monolayer or polymolecular tunic.Chemistry
Self-assembling technique, the mainly atom of adsorption molecule and the surface of solids, molecule etc. are adsorbed, electronics transfer, exchange or public affairs occur
Have, so that sorption chemical key is formed between adsorbate and the surface of solids, this absorption usually only monolayer.Electrostatic Absorption
Self assembly is to carry out alternating sorbent by the polyelectrolyte to two or more oppositely chargeds, to replace in the surface of solids
Deposition forms the technology of multilayer film.
Inorganic nano sheet layer material with unique material property can also be combined with laminated assembling technology,
Ferguson etc., which is reported, is assembled into multilayer film using the polyelectrolyte and silicate nano piece of nominal price.With a thickness of the more of 200nm
Film structure is regular, and X-ray diffraction signal is obvious.Podsiadlo etc. is prepared using polyvinyl alcohol (PVA) and montmorillonite (MTM)
Superpower polymer nanocomposite membrane material.Nanoscale twins are tightly packed and have clearly planar orientation.Pass through mechanicalness
It can test, author obtains the final tensile strength of simple PVA/MTM composite membrane and Young's modulus is pure PVA polymer film respectively
4 times and 10 times, and by the way that after glutaraldehyde cross-linking, every mechanical performance parameter of multilayer film is even more to increase substantially.It is different from
After mechanical performance, Hammond and its partner have studied addition inorganic nano sheet layer material, the ion transport property of multilayer film.
Such as biomimetic mineralization material is prepared using laminated assembling technology, so that it may oil drilling many aspects are used for, it is widely used, such as drilling well
Borehole wall reinforcing etc..Existing researcher proposes crystalline structure, shape and the side of assembling in control calcium carbonate crystal growth course
Method.Application No. is 200710042997.7 patents to propose a kind of nano layered calcium carbonate bionic composite material material, it be by
Low-molecular-weight organic matter participates in calcium chloride and sodium carbonate reaction process, and guiding calcite forms nanometer thin layer structure, and then makes
The multilayered structure of layer structure directional assembly nano thin-layer.These researchs play the bio-mimetic syntheses of biomineralization material important
Impetus, but still fail to grow into biomimetic material or method and material property with natural whiting structure and need
It further increases.
Summary of the invention
In order to solve the problems in the prior art, the purpose of the present invention is to provide a kind of montmorillonite self assembly and be deposited on solid table
The method in face, this method makes montmorillonite adsorb deposition in the surface of solids using self-assembling technique, and is changed using crosslinking technological and sunk
Integrated membrane performance reinforces deposition film in the deposition effect of the surface of solids.
In order to reach the purpose of the present invention, the technical scheme is that be achieved:
At room temperature, by solid thin-sheet successively respectively alternately immerse polymer solution (0.1 ~ 0.5%wt), montmorillonite suspension (0.5 ~
1%wt) and GA(glutaraldehyde) in solution, carry out alternating sorbent, impregnate adsorption time 5min ~ 10min every time, spent in interval from
The redundant solution that do not adsorbed on sub- water cleaning solid thin-sheet, and with being dried with nitrogen, when alternately invading 20 ~ 200 circulations of stain after,
Montmorillonite sedimentary can be obtained on solid thin-sheet surface.
In the technical program, the polymer be PAA(polyacrylic acid), PVA(polyvinyl alcohol), PVS(polyvinyl sulfonic acid
Sodium) one or more of combination.
The present invention has the advantage that compared with prior art
(1) present invention further enhances sedimentary and solid using montmorillonite self assembly deposition film forming, and by crosslinked action
Compatibility；
(2) present invention can be used in oil drilling borehole wall curing technology, improve wall strength.
