Conjugated, conductive polymers are the key component in the development of flexible displays, low-cost, large-scale displays, and thin-film transistors. However, ever since the seminal discovery of the conductive nature of (“doped”) polyacetylene by Heeger, McDiarmid, Shirakawa, and coworkers, the processing of conductive polymers into devices has been a critical issue. The rigid conjugated po...

The generation of laterally structured patterns of conju gated, conductive polymers on flat substrates is a key step in the development of new technologies for the production of, for example, displays or low cost flexible circuits. Printing and related procedures, in which the pattern of the individual pieces produced can also differ from one another, are patterning techniques suited for mass p...

A power conversion efficiency of 9.02% is obtained for a fully solution-processed polymer tandem solar cell, based on the diketopyrrolopyrrole unit polymer as a low bandgap photoactive material in the rear subcell, in conjunction with a new robust interconnecting layer. This interconnecting layer is optically transparent, electrically conductive, and physically strong, thus, the charges can be ...

The electrochemical behavior of solution species at electrodes consisting of a conductive polymer layer, produced by incorporation of tetrathiafulvalenium ( T T P ) bromide into the cation-exchange polymer Nafion, on various substrates (Pt, Ta, SnO,, n-Si) is described. The voltammetric behavior of the solution species Fe(CN),'and Fey2(where Ye = ethylenediaminetetraacetate) at the Nafion-TTF' ...

The in-plane thermal conductivity increased by factor of 50 for 1.94 %wt. carbon nanotubes in...

The fully plastic ionic polymer actuators based on Poly (vinylidenefluoridetrifluoroethylenechlorotrifluoroethylene) PVDF-CTFE polymer were investigated. The actuator consists of a high conductive electrolyte layer containing EMI-TF ionic liquid sandwiched between two CNT/polymer electrodes. To reduce the modulus of the CNT electrodes and hence enhance the actuation performance of the actuator,...

We demonstrate a nonvolatile, write-once-read-many-times ~WORM! memory device employing a hybrid organic/inorganic semiconductor architecture consisting of thin film p-i-n silicon diode on a stainless steel substrate integrated in series with a conductive polymer fuse. The nonlinearity of the silicon diodes enables a passive matrix memory architecture, while the conductive polyethylenedioxythio...

We present a method to fabricate individually addressable junctions of self-assembled monolayers (SAMs) that builds on previous studies which have shown that soft conductive polymer top contacts virtually eliminate shorts through the SAMs. We demonstrate devices with nanoscale lateral dimensions, representing an order of magnitude reduction in device area, with high yield and relatively low dev...

The dielectric properties and ionic conductivity of novel "ceramic state" polymer electrolytes for high capacity lithium battery are characterized by Radio frequency and Microwave methods in two broad frequency ranges from 50 Hz to 20 KHz and 4 GHz to 40 GHz. This innovative solid polymer electrolyte which is highly ionic conductive (10 S/cm at room temperature) from -40C to +150C can be used i...
