| Abstract: | Studying sliding friction of hydrogels in liquid is important for understanding biological friction. This work applies the non-linear rheology approach to study the friction of elastic hydrogels against adhesive glass in water and in concentrated hyaluronan (HA) solution. Using a rheometer in parallel plate geometry, stress-strain Lissajous curves are obtained from the oscillatory strain sweep test. Non-linearity and energy dissipation are characterized the strain-hardening ratio S, and “energy dissipation occupancy” κ, respectively. For friction in water, a clear transition from a linear viscoelastic to non-linear viscoelastic response occurs at a critical strain amplitude. Whereas, in HA solution, significant friction reduction and non-linear viscoelastic response occurs, related to the rheological behaviors of HA film intercalated at the gel/glass interface. |
