Abstract

A composite polymeric material includes one or more repeating backbone units; one or more polarizable units incorporated into or connected to one or more of the one or more repeating backbone units; and one or more resistive tails connected to one or more of the repeating backbone units or to the one or more polarizable units as a side chain on the polarizable unit, on a hydrocarbon chain linking a polarizable unit to a backbone unit, or directly attached to a backbone unit. The composite polymeric material may be used to form a metadielectric, which may be sandwiched between to electrodes to form a metacapacitor.
