This talk mainly discuss how the selective and controlled weakening of adhesion between polymer-polymer and polymer-metal interfaces can achieve high-resolution, high-yield nanoscale and microscale patterning technologies. We introduces a novel solvent-assisted nanotransfer printing (S-nTP) strategy that can controllably generate extremely fine (down to sub-10 nm) functional nanostructures with excellent transfer yield (~100%). The spontaneous injection of solvent molecules into the interfaces between the thin film polymer replica and adhesive film enables facile switching of the interfacial adhesion and on-demand release of functional nanostructures on receiver substrates. S-nTP is compatible with various metallic, oxide, polymeric materials, as well as colloidal quantum nanostructures and is applicable to almost all surfaces including even biological surfaces. |
