Synthesis of cleavable PS brushes on the surface of silica particles was reported in this paper. Atom transfer radical polymerization (ATRP) initiator was anchored onto the surface of silica particles via dynamic imine bond, and PS brushes were prepared by surface ATRP of styrene. PS brushes could be cleaved from the surface of silica particles in the presence of trifluoroacetic acid. Based on the dynamic properties of imine bonds, pyrene-labeled ...
