Over the past several years, TDA Research, Inc. has been developing solvent processable forms of poly(3,4-ethylenedioxythiophene) commonly known as "PEDOT". Our approach is to make block copolymers with alternating conducting and non-conducting blocks. The conducting segments provide the electronic properties, while the non-conducting segments are designed to promote dispersion. TDA has two lin...

Owing to changes in their chemistry and structure, polymers can be fabricated to demonstrate vastly different electrical conductivities over many orders of magnitude. At the high end of conductivity is the class of conducting polymers, which are ideal candidates for many applications in low-cost electronics. Here, we report the influence of the nature of the doping anion at high doping levels w...

There has been continuous progress in the development for biomedical engineering systems of hybrid muscle generated by combining skeletal muscle and artificial structure. The main factor affecting the actuation performance of hybrid muscle relies on the compatibility between living cells and their muscle scaffolds during cell culture. Here, we developed a hybrid muscle powered by C2C12 skeletal...

Abstract Conductive hydrogels open up new possibilities for neural stem cells (NSCs) transplantation the treatment of neurodegenerative diseases (NDs) and traumatic brain injury (TBI). In this study, a novel carboxymethyl chitosan/gelatin/poly(3,4-ethylenedioxythiophene) (CMCS/Gel-PEDOT) hydrogel with different contents EDOT monomer was prepared by lyophilization in-situ polymerization. The sam...

Novel disubstituted EDOT monomers were synthesized in good yields from 3,4-dimethoxythiophene and (chiral) glycols by transetherification. The stereochemistry of the monomers affects the electronic properties of the corresponding chiral PEDOT derivatives.

The oxidative chemical vapor deposition (oCVD) process is investigated to produce poly (3,4-ethylenedioxythiophene) (PEDOT) thin films on 10 cm diameter Si wafers, involving the SbCl5 liquid oxidant. Process/structure/properties correlations are thoroughly studied, including influence of SbCl5/EDOT ratio, substrate temperature (Tsub), total pressure and duration, thickness, composition, morphol...

Phenolic resin-derived activated carbon (AC) cloths are used as electrodes for large scale electric double-layer capacitors (EDLCs) or supercapacitors. To increase the energy and power density of the supercapacitor, the contact resistance between the carbon cloth and the aluminum foil current collector is reduced by modifying the Al current collectors. Different modified Al current collectors, ...

In this paper, a fully polymeric micro-cantilever with the surface passivation layer of parylene-C and the strain resistor of poly(3,4-ethylenedioxythiophene)/poly (styrene sulfonate) (PEDOT/PSS) was proposed and demonstrated for immunoassays. By optimizing the design and fabrication of the polymeric micro-cantilever, a square resistance of 220 Ω/□ for PEDOT/PSS conductive layer have been obtai...

Conducting polymers can be easily obtained by electrochemical oxidation of aromatic monomers on an electrode surface as a film state. To prepare conducting polymer fibres by electropolymerization, templates such as porous membranes are necessary in the conventional methods. Here we report the electropolymerization of 3,4-ethylenedioxythiophene and its derivatives by alternating current (AC)-bip...

Screen printed carbon electrode (SPCE) has been modified with single wall carbon nanotube/poly(3,4-ethylenedioxythiophene) (SWCNT/PEDOT) composites for the determination of phenol and chlorophenols (phenol, 4-chlorophenol, 2,4-dichlorophenol, and 2,4,6-trichlorophenol). The effect of the modifiers on the electrode characteristics was evaluated and the responses were optimized for the voltammetr...
