Morphology and mechanical properties of the tested polymeric surfaces.

Abstract

<p><b>A</b>. Root mean square (RMS) roughness of all polymeric surfaces; <b>B</b>. Representative photographs of the polymeric surfaces before and after nanoindentation; images are color coded, showing elevated areas in bright and lower areas in dark color. <b>C</b>. Representative nanoindentation force-displacement curves; D. Mean hardness values of all polymeric surfaces, calculated for the maximum load and E. Mean stiffness values for all polymeric surfaces. (n = 60 indentations, mean ± SD, *** for p<0.001).</p
