22. We note that the result (2) differs drastically from the prediction of asperity contact mechanics theories such as those of the Bush et al. [A.W. Bush, R.D. Gibson, T.R. Thomas, Wear 35 (1975) 87] and the theory of Greenwood and Williamson [J.A. Greenwood, J.B.P. Williamson, Proc. R. Soc. Lond. Ser. A 295 (1966) 300].

Int. 40 (2007) 1531], where they report the Young's modulus E = 2.4 MPa for PDMS prepared in the way as in our case, using Sylgard 184 with a base/curing agent mass ratio 10:1. Similarly, Scheibert et al. [J. Scheibert, A. Prevost, J. Frelat, P. Rey, G. Debregeas, EPL 83 (2008) 34003] obtain the Young's modulus 2.2 ± 0.1 MPa.
