Synthesis Of Side-chain Liquid Crystalline Polysiloxanes Research Articles

Study on the Properties of Mesogenic Monomer Exhibiting Blue Phase and Synthesis of Side-Chain Liquid-Crystalline Polysiloxanes

A new type of Side-Chain Liquid-Crystalline Polysiloxanes was synthesized by graft polymerization, using (Trans, trans)- 4-propyl-4’-vinyl-bicyclohexane(3HHV) with platelet texture of a blue phase as mesogenic monomer. Microstructure of monomer and polymer were analyzed by polarizing optical microscopy and X-ray diffraction. Thermal properties of monomer and polymer were researched by differential scanning calorimetry. Meanwhile, spherulite texture of polymeric smectic A phase of liquid crystal polymer was revealed in the cooling cycle by polarizing optical microscopy, and this texture was so uncommon that can hardly be found in the liquid crystalline polymers.
