Atomic force micrographs of crosslinked PPF and PPF/HA disks with different HA contents. (a) 3D scan images (scan size = 50 μm, scan rate = 3.924 Hz, number of samples = 512, and data scale = 2.0 μm). (b) Root mean square (RMS) roughness of the samples. No statistical difference was detected among the sample groups (p>0.05).
