The PUI is a kind of thermotropic liquid crystal, and after it is cured at the high temperature, there are a lot of semirigid structures existing in PUI/ER composites, which can form interpenetrating polymer networks.
Ten of the synthesized compounds were observed to exhibit a thermotropic liquid crystal phase between 51[degrees]C and 123[degrees]C.
A thermotropic liquid crystal has the ability to indicate small temperature differences by changing color when applied in a thin film to the skin.

They found that only one of these polyimides was a thermotropic liquid crystal, suggesting that imide unit might not be a good mesogen.
The volume contains seven papers discussing: new advances in mid-infrared pulse shaping and its application to two-dimensional infrared-spectroscopy and ground-state coherent control, recent applications of local control theory to energy and particle transfer processes in molecules, dynamics of double photo- ionization in molecules and atoms, the electrified liquid-liquid interface, the physics of ultrathin solid-fluid-solid films from surface instabilities to isolated pockets of fluid, dynamics of thermotropic liquid crystals across the isotropic-nematic transition and their similarity with glassy relaxation in supercooled liquids, and a unified analytic theory of complex permittivity of ice Ih and of liquid water in far infrared.
Thermotropic liquid crystals are formed by heating solids and lyotropic liquid crystals are formed by dissolving solids in liquids.
