Abstract
The chain dimensions of a polymer confined between two plates, and interacting with them, are herein studied. The contribution of the excluded volume interaction is evaluated using the mean field theory as originated by Flory. The expansion factor perpendicular to the plate, αz increases monotonously with the distance between the plates, D, when the polymer plate interaction, W, is repellent. However αz decreases abruptly with increasing D when W is attractive. This transition corresponds to the conformational change between the bridge type and the loop type of conformation. The parallel component of the expansion factor, αx decreases with increasing D when W is repellent. At the transition, αx increases abruptly.
