Description

Bar-Cohen, V. Bharti, Z-Y. Cheng, J. Madden, Q. Zhang. The measured conductivities of water hydrated Nafion electro-spun fibers are 1. mS/cm, which are lower than the nominal 110 mS/cm that of H+ Nafion membranes.

Bar-Cohen, V. Page/Article number Title Type Online publication date. The uptake is measured to be around 250 %wt compared to 58 %wt obtained in Nafion films. The ionic conductivity of 110 %wt swollen ionic liquids-Nafion mat composite is computed to be . mS/cm compared to . mS/cm in ionic liquid-Nafion membrane composite.

In many device applications, such as electro-acoustic transducers and actuators based on high strain electroactive polymers, there are many advantages to utilize conductive polymers as electrodes. However, in these applications, a high electric power usually is required which translates to high voltage and high current in the system View.

This paper reports two classes of electroactive polymers developed recently which exhibit very high strain and elastic energy density. In the first class of the electroactive polymer, . the defects modified poly(vinylidene ylene)(P(VDF-TrFE)) polymers, an electrostrictive strain of more than 7% and an elastic energy density above 1 J/cm3 can be induced under a field of 150 MV/m.

This book contains the proceedings of two symposia held at the 2001 MRS Fall Meeting in Boston, covering electroactive polymers.

Increasing research and development efforts have been dedicated to the field of electroresponsive polymers (ERPs), including the development of materials and devices. In addition to their exceptional physical properties and low manufacturing costs, these materials also show remarkable charge storage and electrical properties. One particular class of these materials is the electroactive polymer (EAP), or artificial muscle - a new type of smart material with a broad range of potential applications such as electromechanical devices, energy storage devices, artificial muscles, air filtration, insulation, etc. This book shows research and commercial advances in the field and highlights the significant industry involvement: 3M is implementing piezomaterials in stethoscopes; Measurement Specialties Inc. highlights a range products employing PVDF sensors and EMFIT Ltd. presents ferroelectrets, in which microporous polymers show a piezoelectric coefficient at the level of ~300 pC/N. Additional topics include: sensors and their applications; polymer actuators and their applications; and polymer dielectrics and charge storage applications.
