Figure 4

POM images of PDMS with various wrinkled-wall widths.

The pattern widths are (a) 200 μm, (b) 400 μm, (c) 600 μm, (d) 800 μm and (e) 1 mm. The bottom-right POM image insets in each POM image were prepared to demonstrate the homogeneous alignment state of each sample rotated by 45° relative to the polarisers. (f) The pre-tilt angle of the wrinkled wall as a function of the width variation.
