Figure 5From: The nanoscale phase distinguishing of PCL-PB-PCL blended in epoxy resin by tapping mode atomic force microscopyHeight (a-d) and phase (a'-d') images of the blended film at A 0 = 30 nm. (a, a'): rsp = 0.95; (b, b'): rsp = 0.85; (c, c'): rsp = 0.77; (d, d'): rsp = 0.1. The spring constant is 40 N/m, and the scan size is 500 nm × 500 nm.Back to article page
