Figure 2. (a) Microscope images of 3D-printed moulds (scale bar: 50 μm) and (b) PDMS moulds (scale bar: 50 μm). (c) SEM images of the 3 wt% PCL
and PCL/PLA thin films with different groove architectures: 10/10/10 µm, 20/20/10 µm, 25/25/10 µm, and 30/30/10 µm (scale bar: 50 μm; inset images
scale bar: 1 μm). (d) Rolled and sealed PCL-10 NGC tube showing a photograph of (i) the side view, (ii) top view, and SEM image of (iii) inside the tube
with microgroove topography and (iv) location of the film overlap and sealant (scale bar: 500 μm; low- and high-magnification images scale bar: 500 μm).
