Title: Innovations of David F MacInnes, Jr.
Introduction
David F MacInnes, Jr. is an accomplished inventor based in Greensboro, NC (US). He has made significant contributions to the field of conductive materials, holding 2 patents that showcase his innovative approach to polymer technology.
Latest Patents
His latest patents include an inert electrode comprising a conductive coating polymer blend formed of ortho-methoxyaniline (o-anisidine). This compound can be polymerized by both chemical and electrochemical means to produce polyanisidine, a soluble polymer known for its high electrical conductivity. Also referred to as poly-o-methoxyaniline or PANIS, this polymer can be blended with various other polymers, allowing for the construction of devices with desirable electrical, optical, and physical properties. Notably, oxidative polymerization yields have been increased to 47 percent without any apparent loss in electrical conductivity. PANIS has been successfully blended with polystyrene, polyacrylonitrile, polyethylene oxide, and poly(trimethyl hexamethylene terephthalamide) (nylon) to create free-standing, stable, flexible films and fibers with electrical resistance values that depend on the concentration of PANIS. The applicability of PANIS technology has been demonstrated through the construction of three devices: a switching device that changes color upon the application of positive and negative voltages, an inert polymer electrode, and an electromagnetically shielded connector.
Another significant invention is an electrically conductive gel that comprises an extrinsically conductive gel with a quantity of an intrinsically conductive polymer dispersed within it. This polymer is present in an amount ranging from about 0.03 to 1.6% by weight. Preferred conductive polymers include polypyrrole, polyaniline, polyanisidine, polythiophene, and their derivatives.
