Replica molding-based tribocharging and its use in EHDL. a After being replica molded from a nanotextured polycarbonate (PC) mold, the elastomer replica’s surface acquires tribocharges distributed in close correlation with the nanotexture. b The resulting electric field can subsequently shape the photopolymer at nanoscale through EHDL. In this work, the PDMS nanocup, replicated from a PC nanocone, acquires a nanoring-shaped tribocharge which shapes the photopolymer into a nanovolcano
