|a The growth of polymer brushes on polymer substrates is often challenging because of substrate incompatibility with the organic solvents used for initiator attachment. This letter reports the use of layer-by-layer adsorption of macroinitiators and subsequent aqueous ATRP from these immobilized initiators to prepare polymer brushes on polymeric substrates. Polyethersulfone (PES) films and porous membranes were modified with polyelectrolyte multilayer films, and a previously developed polycationic initiator, poly(2-(trimethylammonium iodide)ethyl methacrylate-co-2-(2-bromoisobutyryloxy)ethyl acrylate), was then electrostatically adsorbed onto these polyelectrolyte films. The immobilized macroinitiator is very efficient in initiating the growth of polymer brushes on PES, as demonstrated by aqueous syntheses of poly(2-hydroxyethyl methacrylate) (PHEMA) and poly(2-(dimethylamino)ethyl methacrylate) (PDMAEMA) films. PHEMA (250 nm thick) and PDMAEMA (40 nm thick) brushes were grown in 2 h from surfaces modified with polycationic initiators. Moreover, this procedure is effective for growing brushes in the pores of PES membranes
