From: Control of the wrinkle structure on surface-reformed poly(dimethylsiloxane) via ion-beam bombardment
(a) AFM images, (b) wavenumber distributions and (c) 2D FFT patterns of wrinkle structures formed on PDMS films annealed at various temperatures. Increased PDMS annealing temperature led to decreased periods of the wrinkle structures that formed during subsequent IB irradiation.
