highly significantp ≤ 0.0001
The effect of coating (B-S, M-S, F-S, P-S), test substrate (glass or OTS-SAM coated glass) and treatment conditions (air or water) was highly significant (df = 16, F = 22.7982, p ≤ 0.0001*) as were many of the interactions, including the three-way interaction of coating*surface*treatment ( SI Text, section 3, Table S4 ).
