| Outline of Final Research Achievements |
Polymer brushes having proton donor and acceptor type functional groups were prepared on silicon wafers by surface-initiated atom transfer radical polymerization of 4-hydroxystyrene (4HS)and 4-vinylpyridine (4VP), respectively. Two silicon wafers, one prepared with a poly(4HS) brush and one with a poly(4VP) brush, were jointed in a 1-cm2 contact area using 5-mL of methanol under a pressure of 120 N at room temperature and successively air-dried to form hydrogen bonds at the brush interface, yielding a lap shear adhesion strength of 843 kPa due to the phenolic OH group with a larger dipole moment. In addition, the adhered specimens smoothly debonded in methanol within 20 min at 298 K. The two separated substrates adhered again with a small amount of methanol. Repeatable adhesion and debonding was successfully achieved by proton donor and acceptor type polymer brushes.
