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

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 commercially available microscope, micrometer scale resolution of the placement three different polymers as well block-copolymer functionalization are achieved. This flexible approach makes rapid prototyping patterns film easily accessible. More details can be found article number 2207762 by Annette Andrieu-Brunsen co-workers.
