WebDec 6, 2012 · The subject of liquid crystals and their use in electronic displays and in non-linear optical systems has become of tremendous importance during the last decade; and the incorporation of liquid crystal units into polymeric materials has led to a group of new materials with diverse properties. Some of these properties have been utilized in new … Liquid crystal polymers (LCPs) are polymers with the property of liquid crystal, usually containing aromatic rings as mesogens. Despite uncrosslinked LCPs, polymeric materials like liquid crystal elastomers (LCEs) and liquid crystal networks (LCNs) can exhibit liquid crystallinity as well. They are both crosslinked LCPs … See more Liquid crystallinity in polymers may occur either by dissolving a polymer in a solvent (lyotropic liquid-crystal polymers) or by heating a polymer above its glass or melting transition point (thermotropic liquid-crystal … See more LCPs are categorized by the location of liquid crystal cores. Main chain liquid crystal polymers (MCLCPs), as the name indicates, have liquid crystal cores in the main chain. To … See more Finkelmann first proposed LCEs in 1981. LCEs attracted attention from researchers and industry. LCEs can be synthesized both from polymeric precursors and from monomers. LCEs can respond to heat, light, and magnetic fields. Nanomaterials can be introduced … See more Because of their various properties, LCPs are useful for electrical and mechanical parts, food containers, and any other applications requiring chemical inertness and high strength. … See more Same as the small molecular liquid crystal, liquid crystal polymers also have different mesophases. The mesogen cores of the polymers will aggregate into different mesophases: See more Mesogens in LCPs can self-organize to form liquid crystal regions in different conditions.
