Description
Technical Field
The invention relates to a divisional application of a Chinese patent 'a semiconductor composite material based on black phosphorus alkene, a preparation method and an application', wherein the application date is 11 months and 10 days in 2017, and the application number is 201711102151.8. The invention belongs to the field of semiconductor composite materials, and relates to a preparation method and application of a black phosphorus alkene-polyaniline compound.
Technical Field
The polymer semiconductive material has wide application prospect, and is mainly used for stranded conductors and insulated shields of medium and high voltage cables in the cables by taking the electric field as an example. In addition to the structural type conductive polymers, other conductive polymers are prepared by adding a conductive filler to the polymer to prepare a conductive material. The filler mainly used is conductive carbon black, and a large amount of carbon black (30-50 mass percent) is often required to be added, but the mechanical properties of the material are affected by the excessively high content of the carbon black. Graphene is a novel carbon nano material with a two-dimensional structure, adjacent carbon atoms in the graphene are combined through covalent bonds, electrons on a p-orbit of each carbon atom can freely move in a large pi bond, so that the graphene has excellent conductivity, the conductivity can reach 106s/cm, and the conductivity of a polymer can be greatly improved by taking the graphene as a filler.
However, since the specific surface area of graphene is very large, van der waals forces between sheets make it very easy to agglomerate. Therefore, when graphene is added into a polymer, due to poor interface effect between the graphene and the polymer, an agglomeration phenomenon is often easy to occur, so that the graphene is difficult to disperse in the polymer. The dispersibility of graphene in a polymer is effectively improved by chemically modifying the graphene, but the complete conjugated structure of the graphene is destroyed, so that the performance of the graphene is reduced, and the practical application of the graphene is influenced.
Black phosphorus is a crystal having a wavy layered structure similar to graphite, and atomic layers thereof are bonded by van der waals force and easily exfoliated into single or few layers of nano-platelets. In the monoatomic layer, each phosphorus atom and 3 adjacent phosphorus atoms form a pleated honeycomb structure with covalent bonds, the black phospholene is a natural p-type semiconductor, when valence band electrons jump to a conduction band, the valence band electrons are vertically transited, and the wave vector of the electrons is unchanged, so the black phospholene has a direct band gap, no matter how many layers are stripped, the band gap is a direct band gap, the number of layers can be regulated and controlled within the range of 0.3eV to 1.5eV, the black phospholene has obvious anisotropy, the elastic modulus in the X direction is small, and the effective mass of crystal electrons is only 0.1-0.2 m0This determines that the black phosphorus alkene has higher electron mobility, and the electron mobility of single-layer black phosphorus alkene can reach 10000cm2V · s. But the application of the black phosphorus alkene in the field of semiconductor composite materials is less.
