Thermally Switchable Aligned Nanopores by Magnetic-Field Directed Self-Assembly of Block Copolymers

Authors


Abstract

A scalable approach for developing large area polymer films, with stimuli responsive vertically aligned nanopores is reported. Magnetic fields are used to create highly aligned hexagonally packed block copolymer cylindrical microdomains with order parameters exceeding 0.95. Selective etch removal of material yields nanoporous films which demonstrate reversible pore closure on heating.
