Description
Summary:In the present work, a wide temperature range blue phase liquid crystalmixture is synthesizedby mixing nematic liquid crystal with chiral dopant. The blue phase was observed during both heating and cooling cycles. The blue phase was observed in the temperature range of 3° which may be useful for practical applications. The micro-textures and phase transition temperatures of synthesized mixtures were analysed by polarizing optical microscopy. Transition temperature and texture studies were also studied in pure nematic liquid crystals for comparison purpose.
