Anomalies in the twist elastic behaviour of mixtures of calamitic and bent-core liquid crystals

Abstract: The splay, twist and bend elastic constants (K 11 , K 22 and K 33 ) have been measured as a function of temperature in bent-core/calamitic mixtures based on three different calamitic materials (5CB, 8CB and ZLI1132) and two bent-core dopants. The behaviour of the splay and bend constants are as expected; a reduction in K 33 of~20%, in line with predictions from mixing rules and other observations. Interestingly, no change is seen in the splay constant, K 11 of the calamitic hosts. Surprisingly though, the twis… Show more
