DIELECTRIC MATERIAL CONTAINING DIPOLAR MOLECULES

摘要

Dielectric materials having a high dipole moment density are provided. The high dipole moment density is achieved by the use of a substituted alpha -amino acid, such as N-trimethyl glycine and related homologues having non-polar sidechain groups, with three alkyl substitutions on the nitrogen of the alpha -amino group. These molecules have a high dipole moment and small volume, allowing rapid rotation around the alpha -amino, carboxyl dipole. N-trimethyl glycine alone or in combination with one or more homologues is preferably provided as a solute in a liquid dielectric solution. Alternatively, these molecules are provided as substituents on a linear polymer.
