We have studied the effect of an amphiphilic fatty acid, Stearic Acid (StA), on the phases, wetting and polarization properties of the liquid crystalline substance N-(4-Methoxybenzylidene)-4-butylaniline (MBBA), through Differential Scanning Calorimetry and Optical Polarization Microscopy. Metastable and mesophases disappear for a MBBA:StA = 1:5 mixture. This mixture wets Si(111) and dewets Si(100) surfaces while pure MBBA dewets both. Films of this mixture also show better polarization than the pure sample.
