ELECTRONIC DEVICE

摘要

ELECTRONIC DEVICE A membrane of an ionic pendant-containing, waterinsoluble copolymeric poly(amino acid) composed of a first moiety derived from a first amino acid which gives a watersoluble poly(amino acid) with ionic groups of carboxyl and/or amino groups as the pendants to the molecule, e.g., glutamic acid, aspartic acid, lysine and ornithine, and a second moiety derived from a second amino acid which gives a water-insoluble poly(amino acid), e.g., leucine, alanine and methionine, in a specified molar proportion serves as a functional element of an electronic device such as a nonlinear resistor capable of working in an aqueous medium and exhibiting a non-linear voltage-current relationship or a phenomenon of hysteresis in the voltage/current scanning.
