Self-Doped Conducting Polymers
Tech ID: 10005 / UC Case 1985-247-0
Brief Description
A composition for a self-doped conducting polymer. These polymers are capable of decreased response times in doping operations and of maintaining a stable, doped state for longer than traditionally doped polymers.
Background
Traditionally doped conducting polymers consist of either acceptor-doped p-type material that has free positive charges or donor-doped n-type material that has free negative charges. In either case, charge movement is dependent upon the external acceptor or donor functionality. During electrochemical cycling between neutral and ionic states, ions must migrate in and out of the bulk polymer, limiting the rate at which the cycling can occur. To overcome this, self-doped polymers have been developed to avoid the external doping functionality and thus respond more quickly to electrochemical cycling.
Description
Researchers at the University of California, Santa Barbara have developed a composition for a self-doped conducting polymer. These polymers are capable of decreased response times in doping operations and of maintaining a stable, doped state for longer than traditionally doped polymers. They exhibit conductivities on the order of 1 S/cm and are applicable in battery electrodes, electrochromic displays, and semiconductor devices.
Advantages
- Decreased response time in electrochemical or electrochromic doping and undoping operations
- Maintain a stable, doped state for long periods of time
- Conductivities on the order of 1 S/cm
Applications
- Battery Electrodes
- Conductive Layers in Electrochromic Displays
- Semiconductor Devices
- Field-Effect Transistors
- Schottky Diodes
