We analyze the structure and phase behavior of long wormlike polymers sterically confined between two parallel, structureless walls, separated by a distance W. We focus on the case where W is comparable to the persistence length of the polymers, , where L is the total contour length of a polymer. We find that three distinct phases (uniaxial, biaxial and condensed) may exist, depending on the polymer density and W, for wormlike chains interacting with each other through the excluded-volume interaction.
