Metal oxides are a group of compounds that are now intensively studied because of their wide use in modern ceramic materials, composites, nano-composites, etc., with new special properties. Many oxides are used as electronic materials for their electrical, magnetic and optical properties. The mechanisms of corrosion of metals and their alloys, as well as the mechanism of reduction in metallurgi...

Ionic polymer-metal composites IPMCs consist of a perfluorinated ionomer membrane usually Nafion® or Flemion® plated on both faces with a noble metal such as gold or platinum and neutralized with a certain amount of counterions that balance the electrical charge of anions covalently fixed to the backbone ionomer. IPMCs are electroactive materials with potential applications as actuators and sen...

Ionic polymer-metal composites IPMCs consist of a perfluorinated ionomer membrane usually Nafion or Flemion plated on both faces with a noble metal such as gold or platinum and neutralized with the necessary amount of counterions that balance the electrical charge of anions that are covalently fixed to the backbone ionomer. IPMCs are electroactive materials with potential applications as soft a...

We are concerned with a model of ionic polymer-metal composite (IPMC) materials that consists of a coupled system of the Poisson and Nernst-Planck equations, discretized by means of the finite element method (FEM). We show that due to the transient character of the problem it is efficient to use adaptive algorithms that are capable of changing the mesh dynamically in time. We also show that due...

Electro active polymers (EAPs) exhibit large electrically induced strains (bending or stretching) with electrical stimuli. EAPs are utilized as actuators in micro gripper and micromanipulator in micro robotics activities. Remote center compliance (RCC) based micro gripper is developed to facilitate insertion of peg-in-hole (PIH) for micro assembly operations. An effect of RCC compliance during ...

Ionic Polymer-metal Composites (IPMCs) are soft actuators and sensors. They generally consist of a thin perfluorinated ionomer membrane, metal electrodes plated on both faces, and are neutralized with certain counter cations, balancing the charge of the anions covalently fixed to the membrane. Under a suddenly applied step function (1 to 3 V), the IPMC in alkali-metal cation forms exhibits a fa...

Results on ion-synthesis and optical absorption properties of silver nanoparticles in various dielectrics are reviewed. Composites prepared by the low energy ion implantation are characterized by the growth of metal particles with a size distribution in the depth from the irradiated substrate surface. Such structures lead to specific optical properties of implanted materials, partially to diffe...

Abstract In this paper, we put forward a method to enhance the output power of ionic polymer metal composite (IPMC) through magnetic field by combining ion-electronic and magnetoelectric effects. Firstly, confirmed that total voltage IPMC deformation originates from vector superposition effects when applied field. The open circuit were experimentally investigated adjusting deflecting frequency ...
