Abstract

The invention provides black phosphorus wrapped with a polymer as well as a preparation method and application thereof. The polymer is a hydrophobic polymer with a water contact angle greater than 90 degrees. The preparation method comprises the following steps of: dispersing to-be-wrapped black phosphorus in an organic solvent solution containing the hydrophobic polymer, so as to obtain a mixed solution; and uniformly mixing the obtained mixed solution with an aqueous solution containing an emulsifying agent, performing sufficient dispersion, and then sufficiently volatilizing the organic solvent to obtain black phosphorus wrapped with the polymer. The black phosphorus is wrapped with the hydrophobic polymer and is completely isolated from oxygen and moisture, so that the stability of black phosphorus in the air is further improved, and the black phosphorus can keep quite good stability in water and even a physiological environment, so that application of black phosphorus in photoelectricity and biomedical photonics is greatly expanded.

Description

technical field

[0001] The invention relates to black phosphorus and its preparation method and application, in particular to a polymer-wrapped black phosphorus and its preparation method and application. Background technique

[0002] Two-dimensional materials refer to layered materials with a thickness of only one or a few atoms, such as graphene, boron nitride, transition metal chalcogenides, and black phosphorus newly discovered in 2013, which have become a research hotspot. This kind of material has some unique electrical, optical, thermal, mechanical and magnetic properties because electrons are restricted to move in two dimensions, and has broad application prospects in new energy, new materials, electronic devices, biocatalysis, etc. Due to its wide tunable direct bandgap, high carrier mobility and superior anisotropic photoelectric properties, black phosphorus has shown great value in the fields of optoelectronics, energy and biomedical photonics. The advanced manuf...
