Description

technical field [0001] The invention relates to a method for preparing a perylene diimide functionalized copper oxide (PDI-CuO) nanocomposite material, belonging to the technical field of nanocomposite material preparation. Background technique [0002] Transition metals have multiple valence states due to their special valence structure. Transition metal oxides corresponding to transition metals are also important functional materials and have a wide range of applications. Among them, copper oxide (CuO) has a narrow band gap of about 1.2 eV and is a typical p-type semiconductor. When the size of copper oxide particles reaches the nanoscale, there will be the unique quantum size effect, surface effect and macroscopic quantum tunneling effect of nanomaterials. For example, it shows extremely high catalytic activity as a photocatalytic material and is used as a photosensitive material in sensors. , and it can also be applied to thermally conductive materials and superconduct...
