Preparation methods of nanopore-arrayed anodic alumina membrane and nanopore-arrayed anodic alumina microchannel plate

The invention relates to preparation methods of a nanopore-arrayed anodic alumina membrane and a nanopore-arrayed anodic alumina microchannel plate. The preparation method of the nanopore-arrayed anodic alumina membrane comprises the following steps of preparation of an alumina membrane and directional pore broadening. The preparation method of the nanopore-arrayed anodic alumina microchannel plate comprises the following steps of preparation of an alumina membrane, directional pore broadening and preparation of a microchannel plate. According to the preparation methods of the nanopore-arrayed anodic alumina membrane and the nanopore-arrayed anodic alumina microchannel plate, the technical bottleneck that the channel aperture of the traditional lead-containing silicate glass microchannel plate cannot be easily reduced is overcome; the difficult problems that the area of the microchannel plate is increased if the ultra-small aperture of the microchannel plate is realized and the like are solved; and the excell
