11. After island growth stops, film growth continues, albeit at a slower rate. In this second stage, growth is homogeneous at all temperatures and results in fully assembled and cross-linked films of higher coverage, as evidenced by the higher contact angle of ∼110°.

13. A crude estimate of this time scale is obtained from the following observation: wiping of the samples immediately after removal from the OTS solution results in a significant loss of OTS coverage and a drop in the water contact angle by as much as 25°. However, wiping a sample after 45 min of removal from solution results in a decrease of water contact angle of only a few degrees, and no loss of coverage can be detected by AFM.
