Conducting Polymers

Conducting polymers are organic polymers that can transport electrical charge, combining the processability and flexibility of plastics with properties commonly associated with semiconductors or metals. Their conductivity arises from conjugated backbones containing alternating bonds; chemical or electrochemical doping removes or adds electrons, generating mobile charge carriers that move along the polymer chain and between chains. In engineering, materials such as polyaniline, polypyrrole, and poly(3,4-ethylenedioxythiophene) support flexible electronics, chemical and biological sensors, electrochromic devices, antistatic coatings, actuators, and energy-storage systems. Their tunable conductivity, lightweight structure, and solution-based processing make them important for low-cost, adaptable electronic and electrochemical technologies.

The word polymer is derived from the Greek words “poly” which means “many” and “mer” which means “parts”. Polymers are long chains of molecules composed of repeating units of smaller molecules, known as monomers. They either occur naturally, such as DNA and proteins, or can be constructed synthetically, like plastics. They have varied structural characteristics, such as linear chains, branched chains, or complex networks, that contribute to the properties that they exhibit. Additionally,...

Source: Roberto Leon, Department of Civil and Environmental Engineering, Virginia Tech, Blacksburg, VA Polymeric materials are widely used in civil structures, with uses ranging from very soft sealants to more rigid pipes in water and wastewater systems. The most basic definition of a polymer is a molecular structure with repeating subunits. The term polymer comes from Greek, where "poly" means many, and "-mer" means basic unit. Monomers, or single mers, are the specific repeating units. With...

2014

The durability of polymers and fiber-reinforced polymer composites in service is a critical aspect for their designs and condition-based maintenance. We present a novel low-cost laboratory testing platform for the investigation of the influence of concurrent mechanical and environmental loadings, and may help design more efficient yet safer composite structures.
