In Physics of Sliding Friction; Persson, B., Tosati, E., Eds.; NATO Advanced Science Institute Series; Kluwer Academic Publishers: Dordrecht, 1996; Chapter 3, p 51. Negative friction forces can be measured even when the real interfacial friction force-the one acting between the two surfaces-is always positive. This effect arises from having "underdamped" conditions when the moving surface overshoots after a rapid slip, just as a weight that is attached to the end of a stretched elastic band or spring will move beyond the equilibrium position when it is suddenly released (if the damping is below critical). It is possible to extract the real friction force from the measured force by a deconvolution of the data, as described in the above two references, but this requires a complex, model-dependent theoretical analysis whenever there is stick-slip.
12. g in thin films have been confusing and contradictory. Some show no effect: Xie, L.; DeMaggio, G. B.; Frieze, W. E.; DeVries, J.; Gidley, D. W.; Hristov, H. A.; Yee, A. F. Phys. Rev. Lett., 1995; 75, 4947.

34. The molecular models of the two relaxation processes were described in ref 1. Polymers with large side chains such as PBMA are known to shear align (in the bulk) with their backbone perpendicular to, and their side chains parallel to, the shear direction: Kaito, A.; Yatabe, T.; Ohnishi, S.; Tanigaki, N.; Yase, K. Macromolecules 1999,32,5647. The molecular model proposed in ref 1 suggested that similar backbone and side-chain orientations occur at the PBMA-substrate interface during sliding, and that these define the two main energy dissipating processes of the system.
