Epub 2016 Feb 12.Polymer brushes have a large potential for controlling properties such as surface lubrication or wetting through facile functionalization. Polymer chemistry, chain density, and length impact on the wetting properties of brushes. This study explores the use of diblock copolymer brushes with different block length and spatial arrangement of the blocks to tune surface wettability. Block copolymer brushes of the polyelectrolyte [2-(methacryloyloxy)ethyl] trimethylammonium chloride (PMETAC) with a contact angle of 17° and a hydrophobic block of (1)H, (1)H, (2)H, (2)H-perfluorodecyl Acrylate (PPFDA) with a contact angle of 130° are synthesized by RAFT polymerization.
