Technical field
The invention belongs to technical field of polymer materials, relate to the preparation field of nanofiltration, anti-penetration wastewater disposal mould material, in particular to the structure and preparation method thereof of random polyether aromatic phosphine (or thioether) the family macromolecule polymkeric substance containing ammonium root and phosphonate groups, be a kind of membrane for water treatment material containing double ion group and preparation method thereof in particular.
Background technology
In recent years, amphoteric ion polymer (not only containing positively charged ion unit but also containing anionic units in polymkeric substance) has become good resistant to pollution material.Ultra-filtration membrane is coated the polymkeric substance of class phosphatide, and the both sexes functional group units wherein contained can improve the flux of film and decreasing pollution (PolymerInternational, 2009,58 (12): 1350-1361).The existence of relative charge in material, makes zwitter-ion surface can form the hydration layer of " free water ", and makes material have good biocompatibility and contamination resistance.At first, (JournalofMembraneScience, 1995,107 (3) 209-218 such as Hawes, JournalofMembraneScience, 2010, 362 (1-2): 326-333) utilize plasma etching technology that zwitter-ion graftedzwitterionic2-methacryloyloxy-ethylphosphorylchol ine2-methacrylic acyloxy-Ethylphosphocholine is grafted to microfiltration membrane technique [19] .Afterthat of ontosurfacesofpoly (vinylidenefluoride) (PVDF) andcellulose polyvinylidene difluoride (PVDF) (PVDF) and cellulose acetate acetate (CA) microfiltrationmembraneswiththeplasmaetching (CA), the surface of Zhaoetal.tetheredthezwitterionic, improve the performance of water treatment microfiltration membrane.But because surface grafting preparation process is complicated, need specific instrument, be thus unsuitable for a large amount of preparation.(the JournalofMembraneScience such as Jiang, 2009,340 (1): 164-170) prepared the random polyacrylonitrile base polymer containing sulfonic acid and ammonium root by direct polymerization and prepared asymmetric ultra-filtration membrane with polyacrylonitrile (PAN) is blended, water flux and the contamination resistance of film all increase.2012, Cao
[deng (JournalofMembraneScience, 2012, adopted aqueous phase free radical reaction prepare novel amphoteric ion polymer PDHD 390-391 (3): 243-253.): and by after surface-coated is in polysulfone supporting layer, prepare the nanofiltration membrane of compound again with glutaraldehyde cross-linking, obtain higher water flux and contamination resistance.But the preparation of these materials is difficult to control, and poor chemical stability, easily decompose.
Polyether aromatic phosphine (or thioether) polymkeric substance due to its chemical stability high, mechanical property, resistance toheat are good, have a wide range of applications at film water process and proton or anion-exchange membrane fuel cells field.Functional groups amino in polyether aromatic phosphine (or thioether) polymkeric substance of ammonification, not only directly can be cross-linked and obtain novel cross-linked polymer compound, and the novel high polymer material that the wetting ability that can be converted into skeleton cation is controlled.Polyether aromatic phosphine (or thioether) application in film water process at present containing ammonium radical ion rarely has report.Through finding prior art literature search, as far back as nineteen eighty-two Kesting, R.E. just prepared the complex reverse osmosis membrane of cellulose acetate and quaternised poly-piperazine phthalamide, there is good thermostability and chlorine resistance [Report (1982), 49pp]; Kovacs in 2011, JasonR utilizes the method for disperseing layer by layer, prepare the reverse osmosis composite membrane of diallyl dimethyl ammoniumchloride/4-sulfonate polystyrene/montmorillonite, improve the selectivity [PMSEPreprints (2011)] of reverse osmosis membrane.
Macromolecular material containing phosphonic acids has that thermostability is high, antioxidant property is remarkable, intermolecular easy formation hydrogen bond, content also may keep the very low feature such as swelling time higher.But more difficult owing to synthesizing phosphonylation polymkeric substance, the polymer materials research therefore for this class is relatively less.
The research simultaneously containing the macromolecular material of phosphonic acids and amino group in polymeric system still belongs to blank at home and abroad, the combination of the two, to play the strong hydrogen bonding effect of phosphonyl group and ammonium radical ion to the selectivity of different valence state ion, be expected to develop that good mechanical performance, swelling behavior are controlled, equipment with high desalinization and flux or macroion optionally novel film materials.
