Summary: Conducting polymers, particularly polypyrrole, were used for surface modification of three different leathers. The polymer was deposited on collagen fibers, forming a thin layer with thickness ranging from 24 to 200 μm. The modified leathers showed changes in mechanical properties and sheet resistances, and their conductivity and electroactivity can potentially be utilized in intelligent leathers for footwear, heating elements, and energy storage.

Summary: In this study, high performance trilayer bending actuators were fabricated by electro-interpenetrating a conducting polymer within a host membrane. The oxidative chemical prepolymerization of EDOT allowed for controlled interpenetration of PEDOT underneath the surface. The increase in local concentration of PEDOT in the electrodes led to a significant increase in charge density and improved the actuator's strain capability.

Summary: Different adaptations for artificial muscles following the natural muscle antagonist actuation principle were introduced in this work, combining responses from Polypyrrole (PPy) films of different polymerization techniques. Through consecutive one-pot electrosynthesis of two layers with different deposition regimes, an all-PPy bending hybrid actuator was successfully produced. The nearly equal expansions upon oxidation and reduction under carefully selected conditions enabled the fabrication of a mirrored trilayer laminate that behaved as a linear actuator, revealing a new perspective on the mixed-ion activity of conductive polymers.

Summary: Conductive inks were developed by combining indium tin oxide (ITO) with polypyrrole. The zeta potentials of the resulting polypyrrole-ITO inks were found to be pH-dependent, with zero zeta potential at pH 5. Thermogravimetric analysis revealed the thermal behavior of ITO and its inks. The conductivities of the inks were measured and compared to the neat polymer, showing excellent conductivity even at low temperatures for LED lighting.

Summary: In this study, a conducting polymer, polypyrrole, was coated on leather made of collagen fibers. The coating process involved the oxidation of pyrrole in a solution containing poly(N-vinylpyrrolidone) and five organic dyes. The coating ensured the uniform coverage of collagen fibers with polypyrrole and the incorporation of organic dyes. The surface morphology and penetration of the conducting phase into the leather body were observed using scanning electron microscopy and optical microscopy, respectively. The polypyrrole coating enhanced the electrical conductivity of the leather, while the organic dyes were expected to affect the polymer morphology and provide antibacterial properties. Among the organic dyes, crystal violet exhibited the lowest sheet resistance and the best antibacterial activity. The coating process was further characterized using infrared spectroscopy, and the mechanical properties of the coated leather were evaluated by cyclic bending tests. The results showed that the polypyrrole-coated leather exhibited good electrical stability and mechanical durability.

Summary: The probability p(knot) of knot formation in polymers exhibits a non-monotonic dependence on bending stiffness, reaching a maximum at L-p approximately equal to 8a, due to the competition between changes in localized knot sizes and free-energy costs. Shrinking knot sizes for a polymer with a fixed length increases the number of slots for knot formation and enhances p(knot). This new explanation provides insights into the behavior of p(knot), unifying the effects of knot size and polymer length.

Summary: In this study, the bending actuation mechanism and electromechanical properties of nanostructured dielectric poly (styrene-b-(ethylene-co-butylene)-b-styrene)/white mineral oil (SEBS/WO) blend films were investigated. It was found that the structure of the films underwent a phase transition when the WO content exceeded 17 wt%. The modulus and polystyrene domain radius decreased with an increase in WO content. The bending displacement of the films showed a linear relationship with the applied electric voltage, while the bending force showed a linear relationship with the inverse of the PS domain radius. These findings provide new insights for the development of nanostructured electroactive elastomers for applications in soft actuator materials.

Summary: Bound states in the continuum (BIC) is an exotic concept describing systems without radiative loss. This study introduces a structurally tunable BIC terahertz metamaterial fabricated using micromachining and characterized using terahertz time domain spectroscopy. The bending angle of the metamaterial is controlled by thermal actuation to modify the capacitance and achieve tuning from a quasi-BIC state to the BIC state. Temporal coupled mode theory (CMT) is used to gain additional insight into the tunable electromagnetic response of the metamaterial.

Electrowetting on dielectric (EWOD) is one method for droplet actuation, but it requires prior definition of droplet positions. Optoelectrowetting (OEW) goes further by allowing changes in electrical parameters through impinging light spots, without the need for predefined droplet positions.
