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.
