Abstract
A computer simulation model of electrodeposition of polymer chains on an impenetrable wall is used to evaluate the power-law scaling exponents (nu(x(y))) for the longitudinal and transverse spread, R-gx(y) similar to Lc(nu x(y)); we find that the exponents nu(x(y)) depend on the field strength, i.e., they are nonuniversal. A conformational crossover is observed for the transverse spread from the bulk with nu(y) similar or equal to 1/3-2/3 to the wall with nu(y) similar or equal to 2/3-1. A similar crossover also occurs for the longitudinal component of R-g but with an opposite trend, i.e., magnitude of nu(x) is larger in bulk than at the wall.
