We present preliminary experimental evidence for the existence of Frank elasticity-induced particle-particle interactions in concentrated suspensions in a nematic carrier. Our model system consists of N-(4-methoxybenzylidine)-4-butylaniline (MBBA; a low molecular weight, thermotropic liquid crystal) compounded with 31.5 vol% zeolite particles. Yield stress and oscillatory measurements on the nematic and isotropic samples (i.e., suspensions with nematic and isotropic carrier), display dramatically different signatures. The yield stress of the nematic system is considerably lower than that of the isotropic material, showing nearly a jump at the nematic to isotropic transition. Under small amplitude oscillations the nematic material exhibits viscoelastic response and memory effects, whereas the isotropic suspension behaves as expected for a Newtonian carrier. Theoretical considerations lend credence to the hypothesis of Frank elasticity-mediated particle-particle interactions.
