چکیده انگلیسی
Polydimethylsiloxane (PDMS) reinforced by nanoclay platelets exhibits excellent mechanical properties for microfluidic systems. We tested PDMS-clay nanocomposite thin films under flat-ended cylindrical indentation and measured the elastic modulus and shear strength. A simple formulation based on a shear-lag model, fed by numerical simulations, was introduced to estimate the interfacial shear strength of thin films. Increase in the nanoclay content improved the elasticity of PDMS-clay thin films but reduced their interfacial shear strength. Shear thinning behavior of nanoclay platelets probably reduced the strength of PDMS nanocomposites. The proposed approach can be used for characterization of any polymeric thin films.
