Special Issue Information

Dear Colleagues,

Electroactive polymers make up a fascinating class of materials that exhibit electrochemical activity in a soft matter platform. As the most promising electroactive materials, electroactive polymers have attracted great interest owing to their chemical and electrochemical stability, high conductivity, and biocompatibility, and because they are mechanically robust for processing and device fabrication. Recent advances and developments in electroactive polymers show that new platforms and technologies can be used to design and fabricate innovative conducting polymer architectures with extensive application in various areas. For examples, electroactive chips for energy devices, sport/medical fabrics for remote sensing and monitoring, soft robotics, etc., are some key demonstration applications currently available. The materials themselves may include conjugated polymers, organic radical polymers, ion-conducting polymers, metal-containing polymers, or hybrid inorganic/organic motifs.

Dielectric elastomer (DE) transducers possess various advantages in comparison to alternative actuator technologies, such as, e.g., electromagnetic drive systems. DE can achieve large deformations, high driving frequencies, and are energy efficient. DEs consist of a dielectric membrane sandwiched between conductive electrodes. Electrodes are especially important for performance, as they must maintain high electrical conductivity while being subjected to large stretches. Low electrical resistances allow faster actuation frequencies. Additionally, a rate-independent, monotonic, and hysteresis-free resistance behavior over large elongations enables DEs to be used as resistive deformation sensors, in contrast to the conventional capacitive ones. This paper presents a systematic study on various electrode compositions consisting of different polydimethylsiloxane (PDMS) and nano-scaled carbon blacks (CB). The experiments show that the electrode resistance depends on the weight ratio of CB to PDMS, and the type of CB used. At low ratios, a high electrical resistance accompanied by a bimodal behavior in the resistance time evolution was observed, when stretching the electrodes cyclic in a triangular manner. This phenomenon decreases with increasing CB ratio. The type of PDMS also influences the resistance characteristics during elongation. Finally, a physical model of the observed phenomenon is presented. Full article
