The combination of high capacity redox active pendent groups and conducting polymers, realized in conducting redox polymers (CRPs), provides materials with high charge storage capacity that are electronically conducting which makes CRPs attractive for electrical energy storage applications. In this report, six polythiophene and poly(3,4-ethylenedioxythiophene)(PEDOT)-based CRPs with a diethyl t...

Abstract: Composites of multiwall carbon nanotubes (MWNTs), electrically conducting polymers like polyaniline (PANI), and poly (3, 4-ethylenedioxythiophene)–polystyrene sulfonic acid (PEDOT: PSS) were prepared by following solution casting method. MWCNTs were functionalized with oxidative acid (5M HNO3) treatment schemes to improve the adhesion between the polymer and carbon nanotubes by a п-п ...

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...
