Ferroelectricity can be detected in systems consisting of liquid-crystalline monomer–polymer mixtures possessing no chiral centers The ferroelectric behavior in mixtures of achiral liquid-crystalline side-chain polymers and achiral liquid-crystalline monomers is reported for the first time. The mixtures manifested high pyroelectric activity, with values of spontaneous polarization close to the theoretical limit and a “figure of merit” comparable to the value of classic organic ferroelectric materials.
