polyimide (plural polyimides)
(chemistry) Any polymer whose monomers are imides; used to make high-temperature resins
For example, when a thin polymer coating (usually a polyimide) is spread on a glass substrate and rubbed in a single direction with a cloth, it is observed that liquid crystal molecules in contact with that surface align with the rubbing direction. Source: Internet
The currently accepted mechanism for this is believed to be an epitaxial growth of the liquid crystal layers on the partially aligned polymer chains in the near surface layers of the polyimide. Source: Internet
The polyimide sheet had a mass of about 10 grams per square metre. Source: Internet
