   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; lateral substituent; electro-optic; ferroelectric; molar mass; polymer; side-group; thin film; polysiloxane;

   Sammanfattning : The potential use of chiral liquid crystalline materials, low molar mass as well as polymers, in technical applications has been recognized for some decades now. A number of interesting phenomena based on the spontaneous ordering of the liquid crystal forming molecules are strong reasons for the research effort in this area. LÄS MER
