“…On the other hand, in electrochemical oxidative polymerization, the conjugated polymer is prepared by a direct deposition of the polymer film on the surface of an electrode from a monomer solution that contains an electrolyte, using electrochemical techniques such as cyclic voltammetry [67]. An example is illustrated in Scheme 7, where Ma et al [68] electrochemically synthesized PEDOT grafted with hyperbranched polyglycerol on the surface of a bare glassy carbon electrode (GCE). In contrast to chemical oxidative polymerization where a chemical oxidizing agent is used, an applied potential that is higher than the oxidation potential of the respective monomer to be polymerized, is required in the case of electrochemical oxidative polymerization in order to initiate polymerization.…”

The evolution and emergence of organic solar cells and hybrid organic-silicon heterojunction solar cells have been deemed as promising sustainable future technologies, owing to the use of π-conjugated polymers. In this regard, the scope of this review article presents a comprehensive summary of the applications of π-conjugated polymers as hole transporting layers (HTLs) or emitters in both organic solar cells and organic-silicon hybrid heterojunction solar cells. The different techniques used to synthesize these polymers are discussed in detail, including their electronic band structure and doping mechanisms. The general architecture and principle of operating heterojunction solar cells is addressed. In both discussed solar cell types, incorporation of π-conjugated polymers as HTLs have seen a dramatic increase in efficiencies attained by these devices, owing to the high transmittance in the visible to near-infrared region, reduced carrier recombination, high conductivity, and high hole mobilities possessed by the p-type polymeric materials. However, these cells suffer from long-term stability due to photo-oxidation and parasitic absorptions at the anode interface that results in total degradation of the polymeric p-type materials. Although great progress has been seen in the incorporation of conjugated polymers in the various solar cell types, there is still a long way to go for cells incorporating polymeric materials to realize commercialization and large-scale industrial production due to the shortcomings in the stability of the polymers. This review therefore discusses the progress in using polymeric materials as HTLs in organic solar cells and hybrid organic-silicon heterojunction solar cells with the intention to provide insight on the quest of producing highly efficient but less expensive solar cells.

“…Also, grafting with non-conjugated polystyrene was reported not to affect the characteristic redox behavior of PPy. Using the electrochemical polymerization approach, conducting polymer poly (3,4-ethylenedioxythiophene) (PEDOT) grafted hyperbranched polyglycerol (HPG) was synthesized by Ma et al [49]. To synthesize the graft conducting polymer (Figure 2), the author introduced hydroxyl groups containing side chains to develop 3,4-ethylenedioxythiophene (EDOT) based monomer, which after subsequent electropolymerization on glass carbon electrode followed by the attachment of alpha-fetoprotein (AFP) antibodies produced antifouling and conducting biosensors.…”

Since the discovery of conductive polyacetylene, conductive electroactive polymers are at the focal point of technology generation and biocommunication materials. The reasons why this research never stops growing, are twofold: first, the demands from the advanced technology towards more sophistication, precision, durability, processability and cost-effectiveness; and second, the shaping of conducting polymer research in accordance with the above demand. One of the major challenges in conducting polymer research is addressing the processability issue without sacrificing the electroactive properties. Therefore, new synthetic designs and use of post-modification techniques become crucial than ever. This quest is not only advancing the field but also giving birth of new hybrid materials integrating merits of multiple functional motifs. The present review article is an attempt to discuss the recent progress in conducting polymer grafting, which is not entirely new, but relatively lesser developed area for this class of polymers to fine-tune their physicochemical properties. Apart from conventional covalent grafting techniques, non-covalent approach, which is relatively new but has worth creation potential, will also be discussed. The aim is to bring together novel molecular designs and strategies to stimulate the existing conducting polymer synthesis methodologies in order to enrich its fascinating chemistry dedicated toward real-life applications.

“…Two main strategies had been followed to produce antifouling conducting polymers, namely the introduction of antifouling moieties with the monomers or the postfunctionalization by grafting hydrophilic units onto the polymeric surface. 12 Protein adsorption has been avoided by means of covalent bonding of nonionic polymers like poly(ethylene glycol), or zwitterionic polymers that showed high fouling resistance due to electrostatic interactions. 13 As well, it has been shown that conducting polymers, such as colloidal dispersions of polyaniline (PANI) showed certain antimicrobial effect which attributed to electrostatic interaction between the polymer and bacterial envelopes.…”
