“…Their biocompatibility nevertheless does not include the passivity against the unspecific adsorption of typical concomitants in biological media, such as proteins or bacteria (biofouling), which generally is not desired in defined biochemical setups . To suppress this uncontrolled adhesion, hybrid materials which are electrically conductive and biorepulsive at the same time are needed (the selectivity for binding the desired entities might be added in later steps, e.g., by the introduction of specific recognition sites). , Of the (intrinsically) conductive polymers known today, , polypyrrole (PPy) and polythiophene (PTh) are most extensively studied because of their high electrical conductivity, their easy and fast preparation, as well as the manifold possibilities for their functionalization. − Both can be easily obtained by chemical or electrochemical oxidation of the corresponding monomers. The latter method is in particular attractive, as electrochemical methods have a high atom economy (and thus a high sustainability) and permit the direct and localized deposition of thin films, whose thickness, morphology, and other properties can be controlled by the exact experimental conditions .…”

Highly conductive and biorepulsive polymer films can be deposited onto gold by electrochemical polymerization of a polyglycerol-modified pyrrole derivative in aqueous solution. The growth of the polymer film is linearly determined by current density and time. Thicknesses of up to 400 nm can be obtained, where the polymerization is self-terminated due to the growth mechanism. Cyclic voltammetry and electrochemical impedance measurements were employed to characterize the film formation dynamics and the conductivity of the films at different thicknesses. Furthermore, the films and their growth were characterized by reflection/absorption infrared spectroscopy, quartz crystal microbalance, atomic force microscopy, as well as contact angle measurements. The films are highly biorepulsive even at thicknesses as low as 10 nm, which could be demonstrated using protein and bacterial adhesion assays, thus opening the opportunity for their use in bioelectrical applications.

“…The advantages of the copolymerization method are that the preparation is convenient and the prepared product has good water solubility. [41][42][43][44] The disadvantage is that due to the different proportions of two or more reactants, it is easy to cause unstable product properties. If the aniline concentration is too high, the water solubility of the product will decrease, and if the aniline concentration is too low, the performance of the PANI in the product will decrease, and it is difficult to determine the optimal reaction conditions.…”

The application of polyaniline (PANI) in various fields is greatly limited by its poor solubility in water.Many methods which could elevate PANI water-soluble ability were used by researchers to expand its application range. In this paper, the research progress of the commonly used preparation methods of water-soluble PANI in recent years is reviewed. The main preparation methods of water-soluble PANI are categorized into four types including monomer modification, controlling the polymerization process, introducing water-soluble groups or substances, macromolecular reaction. They are composed of aniline derivative method, copolymerization, emulsion polymerization method, dispersion polymerization method, acid doping method, compound method, ATRP method. The principles of various methods to achieve water-solubility of PANI are introduced, the research on each preparation method reported before are introduced and their advantages and disadvantages are summarized.

“…The energy difference of these orbitals is the bandgap (E g ) due to Peierls instability, resulting from the different sizes of σ and π. [62][63][64] The larger the conjugation, the more orbital Pz of the adjacent carbons will be superimposed, decreasing the bandgap and making low-energy transitions possible (Figure 5b). [67] Most conjugated polymers are used as donors in the active layer of PSC, being responsible for photon absorption, generation of an electron-hole pair, and transport of holes.…”

One of the most widely used energy sources nowadays is nonrenewable, but the excessive consumption of these resources leads to environmental issues. Therefore, renewable energy sources have received much attention, including photovoltaic energy. A novel technology known as “third‐generation solar cells” is being studied, and in this class, the polymeric solar cells (PSCs) and the perovskite solar cells (PVSKs) can be highlighted. Several researchers are trying to find new ways to improve the energy conversion efficiency (PCE) and long‐term stability of these devices. In particular, PVSK has already demonstrated high PCE, but there is still a long way to go to develop more stable and better processable devices for large‐scale production. In the case of PSC, processability is a positive factor since its flexible films have great mechanical stability and can be processed in roll‐by‐roll systems. However, efficiency is still a challenge for researchers. Nevertheless, both types of devices are good alternatives for silicon cell substitution. However, further studies are needed to address the inherent problems of each device technology and move to large‐scale production.
