Description
Technical field
The invention belongs to conducing composite material preparation and applied technical field, relate to modification conduction filter membrane and technology of preparation method, specially refer to and utilize the cheap filtering material of phytic acid doped polyaniline modification, make non-conductive filtering material have the method for good electric conductivity under neutrallty condition.
Background technology
At present, conducing composite material has widely to be used, as electromagnetic shielding material, energy electrode material, electrocatalysis material, the separation of (electricity) film, detection analysis and response, control field.The filter membrane that wherein conducts electricity is the special membrane material of a class, has simultaneously electric conductivity and isolated by filtration performance.Metal film, carbon film have good electric conductivity, but cost is higher.Composite membrane by nano-carbon material (CNT, carbon nano-fiber, Graphene etc.) doping, composition metal or conductive oxide composition also can have electric conductivity preferably.Wherein, Graphene is the carbon atom of monolayer alignment on two dimensional surface, has that excellent electricity is led, thermal conductance and a mechanical performance, enriches cheaply because of its source, recently obtains broad research in composite membrane Application and preparation field.The compound of conducting polymer and Graphene has stable and good chemical property.
Usually, general organic polymer membrane material is all non-conductive.The method for preparing the composite conducting filter membrane mainly comprises mixes the conduction composition, carries out modification and obtains as metal, carbon dust, nano-carbon material, conducting polymer etc.The complex method of conducting polymer is sneaked into or in-situ polymerization.Contain the conducting polymer monomer such as non-conductive membrane material is placed in: the environment of pyrroles, thiophene, aniline, acetylene and derivative thereof etc., initiated polymerization forms conducting polymer under the effect of dissimilar oxidant.Wherein polypyrrole modification conducting film has been seen a lot of reports: in Membrane Sciences weekly 394 – 395 (2012) 202 – 208, Liu Lifen, the neutral filter cloth of the human gaseous polymerization modifications such as Liu Jiadong, and apply electric field and controlled to a certain extent the film pollution; In Materials Letters 71 (2012) 57 – 59, Lu Xiangjun, the people such as Dou Hui utilize polypyrrole, carbon nano-tube modification graphene film to improve chemical property; Pyrroles's modification can improve hydrophily and the antifouling property of terylene filter membrane.But the cost of pyrrole monomer is very high, has limited the extensive use of pyrroles's conducting polymer materials.
Polyaniline is the lower conducting polymer of relative cost, but the application in the filter membrane conductive modified runs into many problems.1) because the solubility property of polyaniline is relatively poor, be unfavorable for forming even casting solution inversion of phases masking, in particle mode incorporation into membrane, film conductivity can be influenced; Although the deliquescent research of a lot of raising polyanilines is arranged, and solubility is still lower, using solvent is also in the film preparation process, must raise the cost and consume; The recovery of solvent has improved the complexity of process control.2) monomer whose toxicity is large, polymerization speed is very fast, also is unfavorable for process control, forms the firmly controlled conductive layer of pattern; In filter membrane in-situ polymerization conductive modified, the pattern of polyaniline is wayward, is unfavorable for improving its fastness and the regulation and control that keep membrane filtration characteristic; 3) polyaniline of acidic molecular doping attitude, just have electric conductivity preferably, and therefore electric conductivity is better under acid condition; But the easy dedoping of the acid ingredient that adulterates under neutrality or alkali condition causes polyaniline to lose electric conductivity, these feature limits the application of polyaniline.In most water treatments, particularly common biological treatment is all carried out under neutrallty condition, and the filter membrane that therefore conducts electricity is used for water treatment procedure, also need to be necessary to keep acid beyond under scope, particularly neutrallty condition polyaniline-modified film good electric conductivity is arranged.
Recently, researcher Pan Lijia in Processings of National Academy Sciences weekly (2012) 1-6, the people such as Yu Guihua utilize the phytic acid doped polyaniline, find that this material has the electric conductivity under neutrallty condition.But the material for preparing is powder or hydrogel, can't be applied in the real reaction device.The polyaniline of ionic liquid doping it is reported and also has electric conductivity under neutrallty condition in addition.
It is that the restriction film separates, particularly restricts membrane Bio-reactor Technology development bottleneck problem that film pollutes always.Separate and the purification technique weekly in (2011) 1-7 weekly, Liu Lifen, Liu Jiadong, the people such as Gao Bo are by applying electric field at inside reactor, make film surface band negative voltage, activated sludge electronegative in reactor is produced repulsive interaction, membrane contaminant is pushed away the film surface, delay the film pollution course, avoid the fast-descending of membrane flux; In Chem. Res. 35 (1996) 1133 – 1140, S.N. Jagannadh, film pollution that H.S. Muralidhara etc. has utilized electric field controls equally; The something in common of these articles is all to have utilized conducting film, and adding of conducting film is conducive to directly apply electric field, also can be used for the electrochemica biological process as electrode or conducting membrane material, and conductive ion exchange membrane material etc. have widely and use.
At present, the study general of conduction filter membrane is confined to the inoranic membrane field, the research of Organic Conductive Films seldom, and organic film is low with respect to the inoranic membrane cost, has more wide market prospects aspect the sewage disposal of membrane bioreactor.Being correlated with applies the research of electric field decelerating membrane pollution, can adopt the method for membrane module built-in metal conductor electrode, but this method makes modular construction complicated, takies space reactor, also may produce metal erosion, affect the film outlet effect, raises the cost etc.And polyaniline organic conductive filter membrane cost is low, if also have fine electric conductivity under neutrallty condition, just can directly apply electric field and be used for the controlling diaphragm pollution.This has Lai in the electric conductivity that improves the polyaniline under neutrallty condition.The powder or the hydrogel polyaniline that conduct electricity under the neutrallty condition of how other researchers being found, compound being prepared on membrane material, the low-cost filtering material of modification requires study.
Filtering material cheaply, filter cloth particularly, has high flux, can under low pressure filter, be suitable for wastewater treatment, particularly its larger pore structure, be well suited for modification, the surface applies and reacts compound other composition and is difficult for complete plug-hole, still can keep fine strainability and antifouling property.And after modification, the filter cloth cost is still lower.Therefore the present invention is directed to the low-cost filtering material such as filter cloth nonwoven and carry out conductive modified, preparation can be used for the conduction filter membrane of electrolemma process and water treatment field thereof.
