Fig. 5.

Static contact angles (θ_static) of unmodified silicone and silicones bulk-modified with PEO-silane amphiphiles and the PEO-control. Bars are organized as the time after water droplet placement from dark color to light as follows: 0 sec, 15 sec, 1 min, and 2 min. Each bar represents the average and standard deviation of three measurements on three different areas of the same sample. Using single factor Anova, statistically significant differences in θ_static (2 min) (p < 0.05) among all specimens were noted.
