<p>1514308 Capacitors COMMISSARIAT A L'ENERGIE ATOMIQUE 6 Oct 1975 [8 Oct 1974] 40822/75 Heading H1M A dielectric, e.g. of a capacitor, comprises a monomolecular layer or a substrate of a substance having a long aliphatic chain terminating in a hydrophilic group, a further functional group on the chain taking part in hydrogen bonding between adjacent molecules in the layer. Because of hydrogen bonding the layer is stated to have a higher melting point, greater mechanical strength and creep resistance. The substance may have the skeleton CH 3 (CH 2 ) n COOH wherein n is 18 to 30, and have OH or SH substituted in theαor # position. Examples areα-hydroxy behenic acid orα-hydroxy tetracosanoic acid. The hydrophilic group may alternatively be the amide. A plurality of superimposed monomolecular layers may be employed.</p> |
