Average dipole moments of aromatic polymer chains
- High Performance Polymers, 8(3), p.427-431, 1996 .
Recently, certain aromatic polyimides with polar substituents were shown to exhibit piezoelectricity after poling. To help interpret these results, mean square chain dipole moments for model chains were calulated using a rotational isomeric state scheme. Average moments ranged from 1.7 to 3.6 debye2 per backbone link, and correlated well with the magnitudes of the piezoelectric coefficients within the series.
