Problems solved by technology

The advantage of this method is that it is easier to control the thickness of the polymer deposition by controlling the electrodeposition conditions; but the disadvantage is that the yield is low
In short, among the existing methods, there is no method with high yield, suitable for large-scale industrial production, and the performance of the composite material prepared at the same time is good.

Embodiment 1

[0028] a, preparation of organic phase 9 parts of heavy polymer monomer aniline is added in the organic solvent toluene to form an organic solution of aniline;

[0029] b, preparation of inorganic phase Dissolve or disperse 1 part of heavy carbon-containing inorganic material carbon nanotube powder in water to form an aqueous solution, then add the polymerizing agent ammonium persulfate that can completely polymerize the aniline in step a into polyaniline in the aqueous solution, An inorganic solution is formed.

[0030]c. Slowly add the inorganic solution in step b into the organic solution in step a, and carry out the polymerization reaction under constant stirring. After the reaction is complete and the colloid is formed, filter the product to obtain the colloid. And wash with ethanol and distilled water repeatedly until the washing solution is colorless and transparent, and dry in vacuum at low temperature to obtain the carbon nanotube / polyaniline composite material.

Embodiment 2

[0035] This example is basically the same as Example 1, except that the carbon-containing inorganic material used is 1 part of heavy carbon nanotube material, the polymer monomer is 4 parts of heavy pyrrole monomer, ferric chloride is the polymerization agent, and the organic solvent is Chloroform, the stirring method is mechanical stirring, and the prepared composite material is carbon nanotube / polypyrrole.

[0036] Figure 5 It is the infrared spectrum test (FTIR) figure of the carbon nanotube / polypyrrole composite material prepared by the method of this example. Depend on Figure 5 It can be seen that the FTIR pattern of the composite material prepared in this example is a typical infrared spectrogram of polypyrrole, thus proving that the generated polymer is polypyrrole.

Abstract

Disclosed is a method for preparing carbon-containing inorganic materials-polymer composite materials, which has the following steps: a. preparation of organic phase, 0.01-100 portions of polymer monomers by weight are added into organic solvent to form the organic solution of polymer monomers; b. preparation of inorganic phase, 1 portion of carbon-containing inorganic material is dispersed or dissolved in water to form aqueous solution, and then the polymerization agent of polymer monomers in step a is added into the aqueous solution to form inorganic solution; the polymerization agent is non-reactive with water and the addition amount of the agent enables full polymerization of the polymer monomers in step a; c. the inorganic solution in step b is slowly added to the organic solution in step a, and the two solutions are fully mixed and reacted to generate complex colloid; the colloid is then filtered, washed and dried so as to get the polymer composite materials. The method is simple to operate and has high yield, which is suitable for large-scale industrial production; the prepared composite materials are of good performance.

Description

[0001] Field [0002] The invention relates to a preparation method of an inorganic-organic composite material, in particular to a preparation method of a carbon-containing inorganic material-polymer composite material. Background technique [0003] Composite materials are materials with two or more phase structures composed of two or more materials with different properties through physical and chemical compounding. This type of material not only has better performance than any single material in the composition, but also has unique properties that the components do not have alone. [0004] Carbon material-polymer composite material is a kind of inorganic-organic composite material, and its application has the following aspects. ① Aerospace field: Due to its good thermal stability, high specific strength and high specific stiffness, it can be used to manufacture aircraft wings and front fuselages, satellite antennas and their supporting structures, solar cell wings and shell...
