HELLO,
Many liquid crystals are simple ploymeric organic compounds.We tend to think of polymers as flexible(polythenes)
Sp far liquid crystals the polymers have to incorporate a rigid section,either in the long ploymer section (main chain liquid crystals) or attached to the polymer as a side chain
Liquid crystals can be first organized into thermotrophic (temperature dependent)
and lyotrophic (concentration dependent)
within thermotrophic liquid crystals there are high molar mass materials (suitable for polymer) and low molar mass materials
Within the polymeric kind there are main chain polymers where the chains align in a direction,or a chain where there is comb like structures with side chains that hang off the polymer.The director is oriented either along the main chain or parallel to the chains
THANK YOU
