An extensive review of IPMC-like devices that use impedance spectroscopy as characterization. The proposed model considers the structure polymer and aims to be a unique can device in any humidity counterion condition.
The burgeoning electronics industry demands flexible and cost-effective electrodes. Despite their inherent insulating nature, conductive rubber composites offer compelling advantages due to flexibility resilience. Due reinforcing properties high electrical conductivity, these materials can be transformed into viable electrode candidates by incorporating additives like carbon nanotubes (CNTs). This study investigates the influence of dispersion vulcanization methods on mechanical...
Ionomeric Polymer-Metal Composites (IPMC) are smart materials whose electromechanical behavior depends on the electrical stimulus intensity, membrane hydration level, and ionic migration. This paper investigates effects of voltage, relative humidity, counterion type (Li+ K+) a Nafion-based IPMC performance. Instrumentation capable applying an measuring response was developed. The conductivity obtained using Electrochemical Impedance Spectroscopy. Complementary SEM analyses were performed...
Abstract Conductive polymeric composites are exciting for future electronic applications given the possibility to ally electrical conductivity and flexibility. However, high viscosity of plasticized elastomers difficult dispersion conductive fillers in an elastomeric matrix is difficult. This research aimed compare use bath or probe sonication disperse multi‐walled carbon nanotubes (MWCNT) lower‐viscosity natural rubber latex. The MWCNT concentration varied from 0.5 2.5 wt%, coagulated...
Abstract Ionic polymer-metal composites (IPMC) are devices composed of metallic electrodes and an ionomeric polymer membrane in a ‘sandwich’ architecture and. Their main property is electromechanical actuation or sensing based on the movement ions. Metallic commonly used for their high electrical conductivity, malleability, chemical resistance. However, cost noble metals, such as platinum, long manufacturing time, fatigue failure limit application. Therefore, replacement with conductive...
Ionomeric Polymer-Metal Composites (IPMCs) are sandwich-like materials based in a polymeric membrane covered on both sides by metallic electrodes. Its operation mechanism consists of hydrated ions migration response to an external electrical field generated between the electrodes, leading spatially nonuniform mass accumulation which causes device bend. performance as actuator depends mainly environment's relative humidity and stimuli. Consequently, IPMCs present variations electromechanical...
Abstract Ionomeric polymer‐metal composites (IPMC) are advanced materials designed to mimic biological systems. Their performance depends on various factors, including electrical stimulus intensity, membrane hydration, ionic migration, and Young's modulus. However, there is a lack of studies in the literature investigating how water absorption capacity elastic modulus change over time IPMCs. Understanding hydration level variation as function essential because this parameter deviates,...
Desenvolvimento distribuído de software (DDS) é uma forma envolver diversas pessoas no processo desenvolvimento software, o qual pode ocorrer várias formas, seja em grupos próprio local trabalho, outras cidades, ou até outros países. No entanto, diversos fatores são considerados para que essa distribuição tarefas distribuída eficaz. Essa eficácia mensurada por como: redução custos com comunicação entre os membros dispersos fisicamente, sucesso na realização do projeto, satisfação membros,...
