Description
One, technical field
The present invention relates to the preparation of ion film, particularly the preparation of ion self-assembled monolayer and composite multi-layer film.
Two, background technology
Along with light Optronics, information science and sensor technology fast development, the research of photoelectric functional film is subjected to extensive attention.The method that is used to develop the photoelectric functional film in present stage mainly contains magnetron sputtering method, chemical vapour deposition technique, sol-gel process etc., the epoch of optical fiber sensing technology fast development at present, and because Fibre Optical Sensor has the fiber optic communication of being different from, thereby different requirements is arranged for waveguide film.Optical fiber sensing technology uses multiple film, comprise organic film, inoranic membrane and molecule film, require film sensitization to be arranged, and traditional preparation method is difficult to use in prepared composition complexity, kind is various, performance is different film to physics, chemistry, optics, magnetics, mechanics, biology, gas etc. are various types of.For example, it is a kind of normal temperature, normal pressure film technique that ion is self-assembled into membrane technology, can prepare the bio-sensing function film with large biological molecule, and some high temperature film techniques then can't be applied to the preparation of this class film.The ion self-assembled film is a kind of ultrathin membrane technology of preparing, uses the laminated film that this technology prepares polyelectrolyte, colloid, and the laminated film surface evenness is controlled on nanometer scale; In addition, ion self-assembled film technology can be controlled composition and the structure on the film thickness direction, the material of difference in functionality can be combined with each other preparation multilayer, multi-function membrane.The diameter of standard single-mode fiber fibre core has only 9 μ m levels, the diameter of standard multimode fiber fibre core also has only 62.5 μ m, at its end face Cheng Mo is " some film forming ", and technical difficulty is big, and some traditional film preparing technologies batch film forming in this specific substrate of optical fiber has big difficulty.Adopt ion to be self-assembled into membrane technology and can realize " some film forming " at fiber end face, film forming on tens, up to a hundred optical fiber once, thus realize producing in batches.
Purpose of the present invention: adopt the ion self-assembled film technology can the large tracts of land film forming, without limits for the size of substrate; Can control film effectively, and reach nanometer scale; Rete sequence on the film thickness direction is controlled, can allow different materials to be assembled in the film, thus composition and structure on the control film thickness direction, and make film have special performances; Can prepare composition complexity, function is different, purposes is different film multicomponent layer, multifunctional photoelectric function film and sensor sensing film in addition; This method cost is low, can realize that automation mechanized operation carries out mass production.
Three, summary of the invention
Ion self-assembled film technology mainly is with polyelectrolyte, and metal or inorganic nano-particle are raw material, by electrostatic attraction, polyelectrolyte and/or charged nano particle successively is assembled on the substrate, thereby forms the nanostructured function film.Concrete grammar is that the electronegative substrate in surface is immersed in the cationic polymer aqueous solution, under the effect of electrostatic attraction, cationic polyelectrolyte is adsorbed onto substrate surface, and become positive charge by the net charge of the substrate outer surface that cationic polyelectrolyte covered this moment.Substrate is taken out from the cationic polymer aqueous solution, after washed with de-ionized water, immerse again in the anionic polymer aqueous solution, because the effect of electrostatic attraction, the surface of cationic polyelectrolyte, the adsorpting anion polyelectrolyte, the net charge of outer surface becomes negative electrical charge simultaneously.After substrate taken out from the anionic polymer aqueous solution, use washed with de-ionized water, circulation repeats above process, promptly can be made into the multilayer self-assembled film, operation principle of the present invention is: will accompany piece fixture and place on the initial position, entry into service under the instruction of pc machine or single-chip microcomputer drops to test specimen in the reagent, and starter motor also drives stirrer rotation in the reagent, carry out plated film, again lifting clamp and reagent and rotate 60 the degree, drop to deionized water and carry out rinsing, rise after the rinsing, and rotate 60 again and spend towards pouring place, test specimen descends, and the cup of rinsing simultaneously discharges water, after the emptying, start water inlet, it is air-dry with test specimen to restart air-flow after startup is dashed and drenched, and finishes until water inlet, and electric rotating machine is got back to initial position.Lay 4 removable and interchangeable containers on the seal casinghousing surface platform, the 5th is the funnel type container, drenches and air-dry station for dashing.The neodymium nickel cobalt permanent magnet that is fixed on below each container on the motor shaft constitutes magnetic field, and permanent magnet rotates and forms rotating magnetic field when motor rotates, and drives magnetic stir bar and rotates, thereby make liquid obtain stirring.
