“…The benzophenonesa photosensitizersgenerates radicals upon irradiation; these radicals cross-link PDMS by mechanisms we have not established in detail. 4,5 As a result, exposure to UV light increases the Young's modulus of the top layer of PDMS. We assume in this paper a thickness of approximately 2 µm for this top layer.…”

This paper describes the spontaneous formation of patterns of aligned buckles in a thin film of gold deposited on the surface of an elastomer [poly(dimethylsiloxane), PDMS]. The surface of the elastomer is patterned photochemically into areas differing in stiffness and coefficient of thermal expansion. The gold is deposited while the surface of the patterned elastomer is warm (T ∼ 100 °C). On cooling, shrinkage in the elastomer places the gold film under compressive stress. The buckles relieve this compressive stress. The distribution of stresses and buckle patterns is described during the pre-and postbuckling regimes using solutions from calculations describing a model comprising a thin stiff plate resting on a thick elastic foundation.

“…The adhesion between individual PDMS-coated particles is due to the processes that occur at the silicone-silicone interface upon heating [25]. Migrating chainends recombine and extend the pre-existing networks to the previously unoccupied interfacial volume, connecting the adjacent particles.…”
