摘      要：Electrophoretic deposition of polymer chains flowing in a (2+1)-dimensional system is studied by computer simulations. Steady-state surface coverage (θj) is found to decay with the chain s length, i.e., θj∼Lc−α with a nonuniversal exponent α≃0.0–0.9 depending on the magnitude of driving field and temperature. Conformational crossover occurs for chains from a surface or wall to an adjacent bulk region with different scaling exponents for their longitudinal and transverse spread.
