Applications of bile acids (BAs) and bile salts (BSs) in the nanotechnology of functional materials are described. The exceptionally strong solubilization and dispersion power of BAs/BSs is a key factor for the solubilization of dyes, drugs, and polymers for electronic, optical, and biomedical devices, fabrication of composites, based on carbon nanotubes, graphene, diamonds, quantum dots, and polymers for applications in energy storage devices, coatings for corrosion protection of metals, sensors and electronic devices. BAs/BSs have attracted attention for synthesis, design, and surface modification of advanced materials. BAs/BSs are used as reducing, capping, chelating and dispersing agents for the synthesis of nanoparticles of metals and alloys, and low temperature synthesis of stoichiometric nanostructured complex oxides. BAs/BSs exhibit unique selfassembly properties, which are successfully used for the template synthesis of functional nanoparticles of controlled shapes. Particularly important are applications of BAs/BSs in the fabrication of dye sensitized solar cells with enhanced efficiency. Electrochemical strategies are discovered for the deposition of BA films and composites. Of particular interest are the unique gel-forming properties of BAs/BSs, which provide a basis for the synthesis of nanoparticles of controlled size and fabrication of novel materials with advanced functionality.

Bile acids (BAs) are physiologically important biosurfactants (Singh, Metrani, Shivanagoudra, Jayaprakasha, & Patil, 2019), which solubilize cholesterol, lipids, proteins, fatty acids, monoglycerides and vitamins in a human body. The strong solubilization power of BAs is related to their amphiphilic chemical structure, which is fundamentally different from the structures of other surfactants. As a general feature, natural BAs molecules have a steroid nucleus with concave hydrophilic and convex hydrophobic sides, containing OH and methyl groups, respectively (Figure 1a and Table 1). The chemical structures of BAs contain a short hydrocarbon chain with COOH or SO 3 H end groups. As a result, dissociated BAs molecules exhibit anionic properties in solutions. Properties of BAs are influenced by the number of OH groups bonded to a steroid core and nature of anionic groups. Modifying the hydroxyl or carboxyl groups of BAs creates a diverse set of BA-based compounds, maintaining some original properties and introducing novel properties as well. The unique distribution of hydrophilic and hydrophobic domains allows these molecules to self-organize into supramolecular assemblies in water. BAs salts form mixed micelles (Figure 1b) with various water-insoluble molecules and facilitate their dissolution. Moreover, BAs allow dispersion of hydrophobic materials, such as carbon nanotubes (Ata, Poon, Syed, Milne, & Zhitomirsky, 2018). The bifacial amphipathic BAs molecules act as compatibilizing agents between the water-insoluble

Conductive polymers and hydrogels are two of the hot prospect polymer types that are used for new stimuli responsive materials. In this study, one‐step preparation of electroconductive composite hydrogels containing polypyrrole (PPy) and N‐isopropylacrylamide (NIPAM) using free radical polymerization technique was achieved with N,N‐methylenebisacrylamide as a crosslinker and ammonium peroxy disulphate (APS) as initiator, in mixture of water/isopropyl alcohol. The equilibrium swelling degree of the poly(NIPAM)‐pyrrole) electroconductive composite hydrogel was 9.88 g of H2O/g dry polymer. According to TGA results, the thermal stability of the prepared composite poly(NIPAM‐PPy) conductive hydrogel (700°C) hydrogel is higher than that of pure poly(NIPAM) hydrogel (600°C). Furthermore, prepared samples were characterized by FTIR, and SEM analyzes. Later, the samples were pressured into pellets so that electrical impedance spectroscopy (EIS) measurements were taken between 10 and 10 MHz at room temperature. The dielectric constant value of composite poly(NIPAM‐PPy) hydrogel at 10 Hz is almost 10 times higher than that of poly(NIPAM) hydrogel. Both samples' real and imaginary parts of dielectric constant decreased with increased frequency. Samples exhibited non‐Debye relaxation since experimental data fit into dielectric model of Havriliak‐Negami. Moreover, low frequency data yielded d.c. conductivity of the pure and composite samples as 3.74 × 10−11 and 1.02 × 10−8 S/cm, respectively. Real part of impedance at low frequencies also points out ~103 times lower resistance values at 10 Hz for composite poly(NIPAM‐PPy) hydrogel. Therefore, EIS results support that electroconductive composite hydrogel fabrication was achieved using free radical polymerization technique.
