Herein, ketone-functionalized diblock copolymer nano-objects are prepared by photoinitiated reversible addition-fragmentation chain transfer (RAFT) dispersion polymerization of tert-butyl acrylate (tBA) using a poly(diacetone acrylamide) (PDAAM)-based macromolecular RAFT (macro-RAFT) agent in ethanol/water (60/40, w/w) at room temperature. A high polymerization rate is observed via the exposure of visible light (λmax = 405 nm, 0.45 mW cm-2 ) with near quantitative monomer conversion being achieved within 60 min. A morphological phase diagram is constructed by changing the degree of polymerization (DP) of PtBA and the monomer concentration. The morphologies of polymer nano-objects are further tuned by incorporating isobornyl acrylate (IBOA) into the core-forming block. The ketone-functionalized diblock copolymer nano-objects can be shell-cross-linked by reacting with a diamine. Finally, the shell-cross-linked polymer nano-objects are further hydrolyzed and employed as a template for the synthesis of silver composites.
