The invention relates to a novel separation membrane with high performance and a preparation method thereof. The membrane is prepared from high-flux directionally-arranged carbon nanotubes serving as a substrate, and a ZIF (Zeolitic Imidazolate Framework) type metal-organic framework material with high selectivity serving as a separation layer. The preparation method comprises the following steps: (1) preparing a directionally-arranged carbon nanotube substrate on a microfiltration membrane through a vacuum filtration method; (2) growing a ZIF type metal-organic framework material surface layer on the carbon nanotube substrate through an interface method. In conjunction with high transmission properties of inner channels and tube gaps of carbon nanotube material tubes and the three-dimensional micro-pore structure of the ZIF type metal-organic framework material, the prepared novel metal-organic framework material separation membrane based on the carbon nanotube substrate has high permeability and high selectivity in a membrane separation process. The novel separation membrane shows superior separating performance in a nano-filtration process, and a basis is laid for the design and preparation of a large-flow efficient separation membrane.

The invention belongs to the technical field of photoelectric materials, and specifically relates to a hole transport material, a QLED (Quantum dot Light-Emitting Diode) device and a preparation method thereof. The hole transport material comprises p-type metal oxide nanoparticles and graphdiyne dispersed in the p-type metal oxide nanoparticles. The material of a hole transport layer of the QLED device includes the hole transport material. By adding the graphdiyne with high hole mobility into the hole transport layer and by virtue of the excellent hole migration ability of the doped graphdiyne, the hole separation ability and hole migration ability of the hole transport layer in the QLED can be significantly improved, the work function of the film material is adjusted, the hole transport efficiency of the device is improved, and the effects of improving the transport and light emitting-emitting efficiency of the device and prolonging the life of the device are achieved.
