Automated Multi‐ and Block‐Copolymer Writing in Mesoporous Films Using Visible‐Light PET‐RAFT and a Microscope (Small 16/2023)

Abstract

Mesoporous Films An oxygen tolerant, DDMAT-initiated and visible-light induced photo electron/energy transfer-reversible addition-fragmentation chain-transfer (PET-RAFT) allows for direct polymer writing in a mesoporous silica thin film. Using a commercially available microscope, micrometer scale resolution of the placement of three different polymers as well as block-copolymer functionalization are achieved. This flexible approach makes rapid prototyping of polymer patterns in mesoporous silica thin film easily accessible.
