Applications of Surface Initiated ATRP to the Preparation of Polyelectrolyte Brushes for Antifouling, Adhesion Control, Friction Control

摘要

Polyelectrolytes show unique characteristics at aqueous interfaces. High-density hydrophilic polyelectrolyte brushes were prepared on Si-wafer and various substrates by surface-initiated controlled radical polymerization. Chain dimension at liquid/solid interface was characterized by neutron reflectivity. Applications of polymer brushes to super hydrophilic surface, antifouling surface, water lubrication layer and adhesion control layer are presented.
