Session KP01 - Poster Session III.
POSTER session, Tuesday afternoon, March 23
Exhibit Hall, GWCC
Conformation of polymer chains and their density profile are studied using a Monte Carlo simulation of polymer chains driven by an electric field toward an impenetrable wall/surface. A discrete lattice of size L_x \times L_y \times L_z is considered with a large aspect ratio L_x/L_y(L_z). Polymer chains are released from the source end (X=1), far from the wall (X=L_x). In addition to excluded volume, nearest neighbor polymer-polymer repulsive and polymer-wall attractive interactions are considered in presence of a field (E) along x-direction. Kink-jump dynamics is used to move the chain nodes with the Metropolis algorithm. Polymer density grows as the chains are deposited on the wall. Growth of the density profile is studied in detail along with the conformation of chains. Attempts are made to study the variation of conformations of polymer chains in different regions (at/near the wall, soft-bulk, interface, and fluid regimes) as a function of field and temperature.
