We studied a polymer-stabilized ferroelectric liquid crystal presenting a high polymer concentration. These structures exhibit strong interaction between both components of the mixture. This can be demonstrated by applying an electric field during polymerization : it is thus possible to fix both the tilt angle of the director in all mesogenic phases and the layer tilt in the smectic phase.
