    "abstract": "Compression of an adsorbed polymer layer distorts its relaxed structure.\nSurface force measurements from different laboratories show that the return to\nthis relaxed structure after the compression is released can be slowed to the\nscale of tens of minutes and that the recovery time grows rapidly with\nmolecular weight. We argue that the arrested state of the free layer before\nrelaxation can be described as a Guiselin brush structure1, in which the\nsurface excess lies at heights of the order of the layer thickness, unlike an\nadsorbed layer. This brush structure predicts an exponential falloff of the\nforce at large distance with a decay length that varies as the initial\ncompression distance to the 6/5 power. This exponential falloff is consistent\nwith surface force measurements. We propose a relaxation mechanism that\naccounts for the increase in relaxation time with chain length.",
