Abstract:

Biomacromolecules, such as DNA, protein and virus, can only undergo thermal degradation because their dimensions exceed the range of their intermolecular forces. Hence the formation of solvent-free biomacromolecular liquid and liquid crystal materials remains a significant challenge. Here, we briefly introduce the preparation and characterization of solvent-free biomacromolecular liquid crystal materials. Lamellar mesophases of solvent-free thermotropic liquid crystals are formed by electrostatic complexation of biomacromolecules and oppositely charged surfactants. These thermotropic liquid crystals retain the ordering and fluidity of biomolecules, providing great opportunities for their technical applications in water-free environments.

Key words: biomacromolecule, thermotropic liquid crystal, surfactant, electrostatic force
