Abstract
The adsorption and dynamics of a polymer chain on a stripe-patterned surface composed of periodical attractive and neutral stripes are studied by using Monte Carlo simulation. The critical adsorption temperature Tc and pattern-recognition temperature Tr are estimated from the desorption probability, surface contact number, and bridge number. A phase diagram presenting three polymer states, including a desorbed state above Tc, a multi-stripe adsorbed state at an intermediate temperature Tr < T < Tc, and a single-stripe adsorbed state below Tr, is provided for infinitely long chains. Normal diffusion is always observed for a polymer in the direction parallel to the stripe even at low temperature. But in the direction perpendicular to the stripe, the polymer can freely diffuse above Tc, whereas the polymer is confined to one attractive stripe below Tr. However, the adsorbed polymer can hop from one attractive stripe to another at the intermediate temperature Tr < T < Tc.
