Average Dipole Moments of Aromatic Polymer Chains
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 calculated using a rotational isomeric state scheme. Average moments ranged from 1.7 to 3.6 debye...

Zusammenfassung: | 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 calculated using a rotational isomeric state scheme. Average moments ranged from 1.7 to 3.6 debye 2 per backbone link, and correlated well with the magnitudes of the piezoelectric coefficients within the series. |
