Abstract

Measurements of the mechanical properties of the surface of a polyvinyl alcohol (PVA) solution and of a methyl cellulose solution have disclosed surprising differences. The response of the PVA to shearing strain is predominantly viscous, whereas the methyl cellulose is elastic. This is the first observation and measurement of a static shear modulus from the surface of a solution.
