Special Issue Information

Dear Colleagues,

Electroactive polymers (also known as conducting polymers or inherently/intrinsically conducting polymers) are polymers that change their properties as a function of applied electric field. The typically poor conductivities of these polymers relative to many metals has led some scientists and engineers to discount their utility. It is for that reason that the term electroactive polymers is perhaps a better descriptor; the ability of these materials to change properties is what has led to most of the potential applications. In the last four decades, electroactive polymers have transformed from interesting anomalies to promising materials for many applications.  Changes in color have led to applications in electrochromics; changes in volume have practical applications in actuators, drug delivery, and separations; conductivity changes are useful for sensors; stable oxidation/reduction processes allow the materials to be used for energy storage (batteries and capacitors) and static dissipation; and light absorption and emission processes allow the polymers to be useful for photovoltaic and light emitting applications. There are many other electroactive polymer technologies and applications developing as the field is rapidly advancing into new areas of discovery.

We invite the scientific community to submit their contributions, in the form of original research articles and review articles, in all areas of electroactive polymers. We are particularly interested in articles describing 1) synthetic approaches to monomers and polymers, 2) characterization of these polymers, and 3) applications of electroactive polymers in areas including photovoltaics, light emission, electrochromics, sensors, drug delivery, energy storage, actuators, static dissipation, and novel applications. 

It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

Polythiophenes (PTs) constitute a diverse array of promising materials for conducting polymer applications. However, many of the synthetic methods to produce PTs have been optimized only for the prototypical alkyl-substituted example poly(3-hexylthiophene) (P3HT). Improvement of these methods beyond P3HT is key to enabling the widespread application of PTs. In this work, P3HT and two ether-substituted PTs poly(2-dodecyl-2H,3H-thieno[3,4-b][1,4]dioxine) (PEDOT-C12) and poly(3,4-bis(hexyloxy)thiophene) (PBHOT) are synthesized by the FeCl3-initiated oxidative method under different conditions. Polymerization was carried out according to a common literature procedure (“reverse addition”) and a modified method (“standard addition”), which differ by the solvent system and the order of addition of reagents to the reaction mixture. Gel-permeation chromatography (GPC) was performed to determine the impact of the different methods on the molecular weights (Mw) and degree of polymerization (Xw) of the polymers relative to polystyrene standards. The standard addition method produced ether-substituted PTs with higher Mw and Xw than those produced using the reverse addition method for sterically unhindered monomers. For P3HT, the highest Mw and Xw were obtained using the reverse addition method. The results show the oxidation potential of the monomer and solution has the greatest impact on the yield and Xw obtained and should be carefully considered when optimizing the reaction conditions for different monomers.

Inherently conductive polymers (CPs) can generally be switched between two or more stable oxidation states, giving rise to changes in properties including conductivity, color, and volume. The ability to prepare CP nanofibers could lead to applications including water purification, sensors, separations, nerve regeneration, wound healing, wearable electronic devices, and flexible energy storage. Electrospinning is a relatively inexpensive, simple process that is used to produce polymer nanofibers from solution. The nanofibers have many desirable qualities including high surface area per unit mass, high porosity, and low weight. Unfortunately, the low molecular weight and rigid rod nature of most CPs cannot yield enough chain entanglement for electrospinning, instead yielding polymer nanoparticles via an electrospraying process. Common workarounds include co-extruding with an insulating carrier polymer, coaxial electrospinning, and coating insulating electrospun polymer nanofibers with CPs. This review explores the benefits and drawbacks of these methods, as well as the use of these materials in sensing, biomedical, electronic, separation, purification, and energy conversion and storage applications.
