A extraordinarily facile nanofabrication approach that enables sub-10 nm resolutions through the synergic combination of nanotransfer printing (nTP) and the directed self-assembly of block copolymers is introduced. The approach was realized by achieving the uniform self-assembly of polydimethylsiloxane (PDMS)-containing block copolymers on a PDMS mold through the stabilization of the block copolymer thin films. This simple printing method does not require liquid bridges or heat for its implementation and can be applied on oxides, metals, polymers, and non-planar substrates without pretreatments. The fabrication of well-aligned metallic and polymeric functional nanostructures and crossed wire structures is also presented. This methodology would be particularly useful for enhancing the performances of printed electronic devices due to its extremely high resolution, large-area scalability, cost effectiveness, and versatility. |
