Fabrication of pSi-pDEAEA composite films. A piece of flat silicon is subjected to electrochemical etching using HF as an electrolyte followed by (1) thermal oxidation, (2) the oxidized pSi film is functionalized with the silane, (3) the DEAEA monomer is subjected to RAFT polymerization reaction, and (4) the pDEAEA is spin-coated onto the surface.
