Durability of self-assembled monolayers on aluminum oxide surface for determining surface wettability
Source abstract
Abstract
Abstract The durable non-wettability of functionalized aluminum oxide (Al 2 O 3 ) thin films coated with two different self-assembled monolayers (SAMs), phosphonic acid (HDF-PA) and trichlorosilane (HDF-S), was investigated by a water flow test method. After exposing the surface to 5 L of water droplets, the contact angle of HDF-S coated Al 2 O 3 thin films remained at the initial value of ∼102.7°, while the contact angle of HDF-PA coated Al 2 O 3 thin films decreased from an initial value of ∼99.9° to a value of ∼69.3°. Thermal annealing effect at various temperature post formation of the self-assembled HDF-PA on the Al 2 O 3 were investigated and shown to enhance the durability of SAMs with a constant contact angle (∼100°) annealed at 100–150 °C.
