    • The PDMS oligomers were synthesized by ionic polymerization and supplied to us by Dow Corning Corporation. The number averaged molecular weights of these polymers were determined by gel-permeation chromatography and NMR. Oligomers having the following M were used: 1.3, 1.85, 2.738, 4.44, 8.88, 18.72, 52.17 kg/mol.

    • These advancing and receding works of adhesion are essentially the strain energy release rates (G). In the advancing mode, the energy to close the crack comes from the thermodynamics work of adhesion (W), which is equal to the strain energy release rate (G) plus the energy loss (φ) due to viscoelastic deformation of the polymer. Thus the measured strain energy release rate is less than the work of adhesion, i.e., G = W - φ, Conversely, when the crack is opening, the viscous dissipation adds to the strain energy release rate, as the material must be deformed before it detaches from the surface, thus increasing the receding work of adhesion (G = W+ φ). See the following reference for more details: Johnson, K. L. In Microstructure and Microtribology of Polymer Surfaces; ACS Symposium Series 741; American Chemical Society: Washington, DC, 2000; pp 24-41.
