Description
Technical Field
The invention relates to a nano composite material using polyaniline as a main body, in particular to a three-phase nano composite material consisting of polyaniline, montmorillonite and rare earth nanoparticles, belonging to the polymer composite material technology.
Background
Polyaniline is a novel functional polymer material, has unique chemical, electrical, optical and thermal properties, has wide application prospect in the fields of energy, electromagnetic shielding, corrosion prevention, electrochromism and the like, and is a conductive polymer which is expected to be widely applied. Polyaniline is a macromolecule with strong interaction and conjugated big pi bonds, the processing performance is poor, and the polymer loses conductivity due to dedoping. Because the montmorillonite has the functions of lamellar structure, heat conduction, self lubrication and the like, the electric conduction percolation threshold can be reduced after the montmorillonite is compounded with the lamellar polymer. The two-phase composite material prepared by the montmorillonite and the aniline through polymerization can improve the surface structure of the montmorillonite, play the synergistic effect of the polyaniline and the montmorillonite and provide good filler for preparing the filled conductive polymer composite material.
Montmorillonite is widely used as a filler for heat-resistant polymer composites and conductive polymer composites due to the particularity of montmorillonite. The higher the filler content in a certain range, the better the performance of the composite material, but the mechanical properties of the material are reduced, and particularly the toughness of the material is obviously reduced. One effective way to improve the performance of the composite material is to uniformly fill inorganic particles into the polymer in a nanometer level, so that the thermal property, the electrical property and the mechanical property of the polymer can be improved, but the traditional method is difficult to uniformly disperse the filler on a nanometer level; because the chemical structures and physical forms of the filler and the polymer are greatly different, the interface modification technology is difficult to completely change the interface between the filler and the polymer matrix to reduce the interfacial tension and realize the nanoscale uniform dispersion and the interfacial adhesion at present. Therefore, the composite material cannot reach the molecular dispersion level, but only belongs to a micro-mixed material, and the improvement of the toughness, rigidity, heat resistance and electrical property of the material is influenced. Another improved approach is to polymerize polymer monomers between layers of montmorillonite to form a composite. However, since the interlayer spacing of montmorillonite is less than a few nanometers, oily polymer monomers are difficult to penetrate into the interlayer of the water-based montmorillonite, and the performance of the formed composite material is also not improved ideally.
The emulsion intercalation one-step polymerization method is that emulsion self-assembly is formed by relying on a surfactant to prepare rare earth nanoparticles, a polymer monomer is used as an oil phase, a mixed rare earth ion aqueous solution is used as a water phase to form reverse micelle microemulsion, the rare earth particles are uniformly dispersed in the oil phase to form a thermodynamically stable emulsion system, then the emulsion is intercalated between the lamella layers of organic montmorillonite (O-MMT), an initiator polymer monomer is added to directly carry out in-situ polymerization to prepare the polyaniline/montmorillonite/rare earth nanoparticle ternary nanocomposite, and a novel preparation method is provided for the ternary nanocomposite. The method has the advantages of simple preparation process, short preparation time, high production efficiency and low cost, and the prepared composite material has good mechanical property, electrical property and thermal stability, and also has good processability of organic polymers, so the method has a very wide application prospect.
