AFM topography images of the four polymers used in the study to compare surface roughness between the hydrophobic and hydrophilic polymers. The surface roughness (nm) for the polymers were: A) CarboSil = 0.873 ± 0.048 B) RTV = 2.257 ± 0.458 C) SP60D60 = 0.360 ± 0.099 D) SG80A = 0.362 ± 0.003. Data represents mean ± SD. (n=3)
