Fabrication of Nitrogen-Doped Mesoporous Carbon With Tunable Pore Size via Self-Assembly of Poly(4-Vinylpyridine)-Block-Poly(2,2,2-Trifluoroethyl Methacrylate).

ABSTRACT: Precise control of pore structures of nitrogen-doped mesoporous carbon (NMC) is still challenging. In this study, we address this issue by developing a soft-template approach based on the molecular design of block copolymers, enabling systematic tuning of nanostructures. Specifically, we synthesized poly(4-vinylpyridine)-block-poly(2,2,2-trifluoroethyl methacrylate) (P4VP-b-PTFEMA) via reversible addition-fragmentation chain-transfer (RAFT) polymerization and employed it as a soft template for fabricating NMCs. The P4VP block selectively interacts with phenol-formaldehyde resol, enabling retention of microphase-separated morphology during carbonization, while the fluorine-containing PTFEMA block enhances phase separation through strong segmental repulsion. Ordered morphologies, including c
