Notes:
Solvent coating is an important commercial technique utilized in fabricating thin films. In certain cases, undesirable strains may be built into the composite as the solvent is removed. The stress field in a two-layer sample and its distribution along the interface have been analyzed. By considering the shrinkage of the solvent cast film equivalent to applying an axial compressive load, interfacial expressions were derived which are valid for solvent drying of solution cast films. Experimental procedures and measurements are presented for the solvent casting of thin brittle films onto flexible polymeric substrates. Interfacial strains are determined and their dependence on accurate material property measurements is evaluated. The relation between the bulk and interfacial strain is illustrated.
