ABSTRACT: We map the requirements and design rules for dielectric materials that
target large scale energy storage applications of electrostatic capacitors. The
molecular unit (dielectrophore) must
contain three main components: a polarizable subunit having large electric
dipole, an isolating subunit which prevents current leakage, and a structural
element that promotes self-assembly of molecules in solution and in mesophase
and promotes crystallization in the process of film formation. This structural
subunit is necessary for high molecular density and enhanced resistivity of
film. The process engineering steps required for the supramolecular assembly
and crystal film formation (cascade
crystallization) are addressed.
