Abstract
When a polymer coil approaches an adsorbed layer (made with the same polymer), two successive processes take place: a) entry, where the coil “reptates” in a hostile environment of other chains, up to the moment where it establishes a first direct contact with the adsorbing wall, b) spreading, where the chain crawls in the vicinity of the adsorbing wall, and ultimately reaches its large final number of wall contacts. The spreading process has recently been detected in pulsed experiments of Cohen-Stuart and Tamai, where the hydrodynamic thickness of the layer is monitored after chain addition. We present tentative scaling laws for both entry and spreading.
