Polydimethylsiloxane deformation mechanisms

An investigation of the mechanism of adhesive failure of polydimethylsiloxane elastomers was conducted [75]. The study showed that the total adhesive failure energy could be decomposed into energies for breaking chemical bonds, breaking physical bonds and deforming the bulk viscoelastic elastomer.

Many of the optofluidic devices are made of a soft elastomer, polydimethylsiloxane (PDMS). In this entry we focus on a specific group of tunable optofluidic devices of which the tuning relies on elasticity of PDMS. The mechanical tuning method is achieved by modifying the geometry of the device upon applying internal or external forces, hence deforming the elastomeric components that directly or indirectly alter the optical properties of the device.
