From: Control of the wrinkle structure on surface-reformed poly(dimethylsiloxane) via ion-beam bombardment
Schematic diagram illustrating the proposed mechanism whereby shorter wrinkle wavelengths formed in PDMA samples annealed at higher temperatures prior to IB irradiation.
(a) PDMS annealed at low temperature, yielding low Young’s modulus of the PDMS substrate; (b) PDMS annealed at high temperature, yielding high Young’s modulus of the PDMS substrate.
