Introducing Functionality to Fluorinated Electroactive Polymers

Electroactive polymers for sensing

Electromechanical coupling in electroactive polymers (EAPs) has been widely applied for actuation and is also being increasingly investigated for sensing chemical and mechanical stimuli. EAPs are a unique class of materials, with low-moduli high-strain capabilities and the ability to conform to surfaces of different shapes. These features make them attractive for applications such as wearable s...

Electroactive Polymers for Robotic Applications

Heavily Fluorinated Electronic Polymers

Building blocks, containing majority fluorine content by weight, for PPEs and PPVs have been synthesized. Some of the monomers were shown to give exclusively fluorous-phase soluble polymers, the syntheses of which were achieved by fluorous biphasic polymerization conditions. Perfluoroalkylated PPEs were found to have excellent fluorescence quantum yields and photophysical and chemical stability...

WorldWide ElectroActive Polymers EAP ( Artificial Muscles ) Newsletter

1 FROM THE EDITOR Yoseph Bar-Cohen, [email protected] This issue reports the latest progress in the fields of Electroactive Polymers (EAP) and biomimetics. Some of the latest development at the various lab worldwide is reported in this issue. From the perspective of Biomimetics, it is interesting to note that the SPIE’s Conference on Biomimetics has continued to grow in terms of the number of p...

Stability of anisotropic electroactive polymers with application to layered media

The stability of anisotropic electroactive polymers is investigated. A general criterion for the onset of instabilities under plane-strain conditions is introduced in terms of a sextic polynomial whose coefficients depend on the instantaneous electroelastic moduli. In a way of an example, the stable domains of layered neo-Hookean dielectrics are determined. It is found that depending on the dir...
