Abstract
Abstract The dielectric material is constituted by monomolecular layers of an organic substance, the molecules of which have a long aliphatic chain terminating in a hydrophilic group. The substance is selected from the group in which a lateral group is grafted onto the aliphatic chain and is capable of exchanging a hydrogen bond with an identical adjacent molecule.
