Abstract

The invention discloses a soluble polymer PGEA and Dawson polyacid or Dawson vacancy polyacid assembly nanometer hybrid material and a preparation method thereof, which belong to the technical field of the preparation of organic-inorganic hybridization functional materials. The preparation method comprises the following steps of: preparing polyacid aqueous solution and polymer aqueous solution with certain concentration; mixing the two kinds of solution according to different proportions; and oscillating and uniformly mixing to obtain a polymer-polyacid hybrid material. In the invention, the ordered assembly of polymer cations and polyacid functional anions with bioactivity is realized for the first time; the hybrid material preparation process is simple, economic, clean and pollution-free; simultaneously, the electrostatic interaction between macromolecular polymer cations and polyacid anions is utilized, so that the immobilization of the polymer-polyacid hybrid material is realized and high operability is achieved; and the hybrid material has nanometer order of magnitude, which lays an important foundation for the application of the polymer-polyacid hybrid material in the aspectof biology.

Description

technical field [0001] The invention belongs to the technical field of preparation of organic-inorganic hybrid functional materials, in particular to an organic / inorganic nano-hybrid material assembled with water-soluble polymer PGEA and Dawson polyacid or Dawson vacancy polyacid and a preparation method thereof. Background technique [0002] Polyacid compounds are a class of multimetal oxides containing V, Mo, W and other metals. Isopolyanions formed by the condensation of the same oxoacid ions are called isopolyacids. The condensation of different types of oxyacid anions is called heteropolyanion, and the acid is called heteropolyacid. At present, it is known that the atoms of nearly 70 kinds of elements can be used as heteroatoms in heteropolyacids, including all the first series transition elements, almost all the second and third series transition elements, plus B, Al, Ga, Si , Ge, Sn, P, As, Sb, Bi, Se, Te, I, etc. And each heteroatom can often exist in heteropolyan...
