Polymer electret and method of manufacturing the same

A polymer electret, comprising:

• a polymer template;
• and
• a plurality of nanopores having a size of 5 nm to 100 nm, the plurality of nanopores arranged periodically in the polymer template;
• wherein the plurality of nanopores are electrically charged,
• wherein the polymer template and the plurality of nanopores originate from a self-assembly of a block copolymer (BCP) in which at least one first block and at least one second block are micro-phase-separated, the nanopore is formed where the first block is removed, and the polymer template is a self-assembly of the BCP having the first block removed therefrom and including the second block,
• wherein the first block is a self-assembly of a plurality of first polymer chains, and the second block is a self-assembly of a plurality of second polymer chains, and
• wherein the polymer template further includes a fluorine-based polymer.
