Metal-Polymer-Metal System in the High Static Electric Field

Quasi-static Positioning of Ionic Polymer-Metal Composite (IPMC) Actuators

Ionic polymer-metal composites (IPMCs) generate large bending motions under a low driving voltage (about 1 V). In this paper quasi-static actuation of IPMC is investigated with the goal of precise positioning. It is found that IPMC exhibits hysteresis between its bending curvature and the applied quasi-static voltage. The Preisach operator is proposed to model the hysteresis, and its density fu...

An Electric Field Induced Breath for Metal–Organic Frameworks

One of the reasons for the enormous interest in the class of porous metal organic frameworks (MOFs) is their structural flexibility, which is in contrast to the rather rigid zeolites. Kitagawa et al. have coined the term “third generation porous coordination polymers” for systems that undergo structural transformations in response to external stimuli, such as guest adsorption. One of the most d...

Beyond the metal-insulator transition in polymer electrolyte gated polymer field-effect transistors.

We have studied the carrier transport in poly(2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene) field-effect transistors (FETs) at very high field-induced carrier densities (10(15) cm(-2)) using a polymer electrolyte as gate and gate dielectric. At room temperature, we find high current densities, 2 x 10(6) A/cm(2), and high metallic conductivities, 10(4) S/cm, in the FET channel; at 4....
