This review provides detailed information on the synthesis, structure, properties, methods for studying, and areas of application conductive polymers synthesized basis phenylenediamines. Conductive based phenylenediamines are cationic salts highly conjugated by electrochemical or chemical oxidation. Chemical oxidative polymerization has led to formation various functional polymers. Depending re...

Electrically conductive polymer composites filled with carbon black can exhibit the mechanical behavior of a polymer and metallic electrical conductivity. Unfortunately, excessive amounts of carbon black can produce brittle films and too little carbon black can result in low conductivity. Composite conductivity can be dramatically improved by using latex as the matrix starting material. Latex p...

Polymers filled with conductive particles and fibers have been widely used in electromagnetic interference (EMI) shielding, electrical static discharge (ESD), and other regions. In these combinations, the carbon fibers filled polymer composites are special interest due to their excellent mechanical properties and high conductivity as well as good durability to environmental conditions. However,...

The capabilities of biosensors for bio-environmental monitoring have profound influences on medical, pharmaceutical, and environmental applications. This paper provides an overview on the background and applications of the state-of-the-art biosensors. Different types of biosensors are summarized and sensing mechanisms are discussed. A review of organic materials used in biosensors is given. Spe...

We studied membrane activity of the bacterial peptide TisB involved in persister cell formation. TisB and its analogs form multi-state ion-conductive pores in planar lipid bilayers with all states displaying similar anionic selectivity. TisB analogs differing by ±1 elementary charges show corresponding changes in selectivity. Probing TisB pores with poly-(ethylene glycol)s reveals only restrict...

A well-known strategy to improve the electrical conductivity of polymers is to dope them with high-aspect-ratio and conductive nanoparticles such as carbon nanotubes (CNTs). However, these nanocomposites also exhibit undesirable properties such as damage-sensitive and history-dependent conductivity because their macroscopic electrical conductivity is largely determined by the tunneling effect a...
