The first conductive polymers (CPs) were developed during the 1970s as a unique class of organic substances with properties that are electrically and optically comparable to those of inorganic semiconductors and metals while also exhibiting the desirable traits of conventional polymers. CPs have become a subject of intensive research due to their exceptional qualities, such as high mechanical and optical properties, tunable electrical characteristics, ease of synthesis and fabrication, and higher environmental stability than traditional inorganic materials. Although conducting polymers have several limitations in their pure state, coupling with other materials helps overcome these drawbacks. Owing to the fact that various types of tissues are responsive to stimuli and electrical fields has made these smart biomaterials attractive for a range of medical and biological applications. For various applications, including the delivery of drugs, biosensors, biomedical implants, and tissue engineering, electrical CPs and composites have attracted significant interest in both research and industry. These bimodalities can be programmed to respond to both internal and external stimuli. Additionally, these smart biomaterials have the ability to deliver drugs in various concentrations and at an extensive range. This review briefly discusses the commonly used CPs, composites, and their synthesis processes. Further highlights the importance of these materials in drug delivery along with their applicability in various delivery systems.

“…To overcome these limits, the scientific community is exploring materials, printing techniques and postprocessing methods to make the 3D-printed objects electrically responsive . For example, conductive inks based on the incorporation of conductive fillers within the polymeric matrix , were purposely formulated for specific 3D printing processes, such as direct ink writing . Alternatively, a valid approach is to deposit electrically conductive coatings on the 3D-printed object surfaces.…”

The methodologies for producing composite materials based on conducting polymers (CPs) and 3D-printed polymeric materials are promising to combine the complex geometries of 3D objects with the charge transport properties of CPs. Among the latter, polyaniline (PANI) has an edge because of its peculiar electrochemical behavior. Synthesis protocols starting from the aniline (ANI) monomer to produce the PANI phase are consolidated; however, a series of controversies are related to the use of this reactant, including a potential toxicity. To obtain safer synthetic procedures for fabricating electrical and electrochemically active 3D composite materials, this research exploits an alternative precursor, namely, the aniline dimer (DANI), for the in situ synthesis of polydianiline (PDANI) via oxidative polymerization within 3D-printed polyethylene glycol diacrylate (PEGDA) objects. Factors such as the molecular weight and swelling degree of PEGDA matrix, as well as the nature of PDANI's doping agents, are found to be crucial to modulate the type of redox mechanism, the charge transport properties, and the impedimetric response of 3D-printed PEGDA−PDANI composites. The possibility to produce PEGDA objects in complex 3D shapes (discs, dumbbell, and trabecular structures), coupled with the charge transport and electroactive performances of the PDANI filler, are promising for exploiting PEGDA−PDANI systems as active interfaces in a wide range of electronic applications.

Polymer semiconductors having solubility in organic solvents can enable facile, low-cost, and large-area solution processes to fabricate electronic devices with various applications. However, it has been a challenge to build complicated circuits by using them due to device-to-device variation. In this study, we designed a diketopyrrolopyrrole (DPP)-based polymer with long and branched alkyl side chains to improve the solubility of DPP polymers. While the long and branched side chains are introduced to the DPP moieties for improved solubility, the far branching point in the side chains was expected to prevent severe steric hindrance of the long side chains and to allow DPP moieties to have π–π interactions and form crystalline structures. To examine the feasibility of using P29DPP-TT as a semiconductor in integrated electronic systems, the electrohydrodynamic (EHD) jet printing technique was used in for local area patterning. The organic field-effect transistors (OFETs) incorporating EHD-printed P29DPP-TT yield promising field-effect mobility (μFET) of 0.55 cm2 V–1 s–1. Complementary inverters and NAND/NOR logic gates were also realized by fabricating OFETs with line-printed P29DPP-TT and polymer gate dielectrics. It indicates that P29DPP-TT with excellent solubility can be applied to solution-processed integrated electronic devices.
