Abstract

The invention relates to a device and a method used for imprinting a nanopore film. The device comprises a first imprinting part and a second imprinting part, wherein a plurality of imprinting elements which are arranged in the form of a preset array and are bulged are arranged on at least one of the first imprinting part and the second imprinting part; while the first imprinting part and the second imprinting part are in mutual extrusion and contact, the first imprinting elements can be arranged on a film between the first imprinting part and the second imprinting part to imprint nanopores which are distributed in the form of a preset array and are controlled in pore diameter; and the first imprinting elements have the same dimensions and configurations. The device can imprint the film with multiple nanopores which are distributed in the form of the preset array, penetrate through the film body and are basically the same in pore diameter. The film is widely applied because of expectedpermeability and low fluid resistance.

Description

technical field [0001] The present disclosure generally relates to the field of preparation of nanomaterials. In particular, the present disclosure relates to an apparatus and method for fabricating nanoporous films using nanoimprint technology. Background technique [0002] Membranes for filtering particulate matter, such as ultrafine particles, have a wide range of applications, for example, they can be used in masks or protective clothing to block virus particles, in air purification devices to block airborne pollutant particles, in It is used in the filtration equipment of hemodialysis equipment to filter blood, or used in water or oil filtration equipment to purify water or oil, and also used as a diaphragm in lithium batteries and reverse osmosis membranes for seawater desalination. [0003] Membranes used to filter particulate matter often contain a large number of small pores. On the one hand, these small holes should be able to pass the fluid carrying particles (s...
