Title:
NANO MEMBRANE, NANO MEMBRANE ASSEMBLY, AND METHOD FOR MANUFACTURING NANO MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2022/025336
Kind Code:
A1
Abstract:
Disclosed is a nano membrane which has improved dustproofness and thus effectively prevents matter, contaminants/dust, and the like from getting into an electronic device such as a PCB or a MEMS microphone, and has no air and sound permeability degradation. The nano membrane of the present invention contains a plurality of pores having an average diameter of 0.5-20㎛, wherein the maximum diameter of each of the pores is 30㎛, the minimum diameter of each of the pores is 0.1㎛, and the porosity of the nano membrane is 50-90%.
