Study of electrical conductivity and dielectric loss of polypyromellitimide at high pressure

High-resolution carbon-13 nuclear magnetic resonance study of conjugation in solid polyimides

“…The unusually good chemical and mechanical stability at high temperatures of aromatic polyimides makes them attractive for a variety of applications. They appear promising for use as high-temperature adhesives in bonding metals such as steel and titanium.1 Their ease in forming charge-transfer complexes with various metal dopants,2 as well as their increase in electrical conductivity at high pressures, 3,4 suggests that they may have potential for use as organic conductors. In addition, the uniform deformation of some biaxially oriented aromatic polyimides makes them amenable for special mechanical applications.…”

Effect of imidization conditions on the morphology of polyimide

“…For polyimides, these fluctuations would be much less as a result of their rapid distribution over all of the link- ages and atoms through the mobile electrons. 36 PI-1 had a better thermal stability than PI-2 because of its higher degree of conjugation along the polymer chain. …”
