“…Also, the peaks appeared at 1202 and 1153 cm 21 were due to CAO vibrations originating from rhodanine molecule. 25 These observed ATR-FTIR peaks proofed the successful synthesis of needle like-TiO 2 /PRh core/shell nanocomposite and also in accordance with the data reported in the literature by Kardas for electrochemical polymerization of PRh and by Jouong et al, for silica/PRh core/shell structure. 5,25 XPS Analyses.…”

The aim of this study was to fabricate needle like-TiO 2 /polyrhodanine nanostructures by polymerizing rhodanine monomer on the TiO 2 nanoparticles' surfaces and investigate their antibacterial activities. The structural, thermal, morphological, surface and electrical properties of non-covalently functionalized nanoparticles were characterized by using FTIR, XPS, elemental analysis, TGA, XRD, SEM-EDX, TEM, contact angle, and conductivity measurements. Characterization results confirmed the formation of needle like-TiO 2 /polyrhodanine (PRh) core/shell hybrid nanostructures. Alterations on the surface and electrokinetic properties of the materials were characterized by zeta (f)-potential measurements with the presence of various salts and surfactants. The f-potential of needle like-TiO 2 was observed to increase from 27.6 mV to 128.4 mV after forming a core/shell needle like-TiO 2 /PRh nanocomposite structure and with the presence of cetyltrimethyl ammonium bromide (CTAB) surfactant. Thereby colloidally more stable dispersions were formed. Antibacterial properties of needle like-TiO 2 /PRh were also tested against Staphylococcus aureus, Klebsiella pneumoniae, and Escherichia coli by various methods and they showed good antibacterial activity. The highest killing efficiency was determined for needle like-TiO 2 /PRh against E. coli by colony-counting method as 0.95. TEM experiments also showed the immobilizations of the nanoparticles on E. coli and revealed the interactions between E. coli and the nanoparticles.

“…In many cases, however, conductive polymers deposited on the metal surface are characterized by high porosity and unsatisfactory adhesion to the substrate [39,40]. One of the newest conducting polymers is polyrhodanine [41,42]. Rhodanine and its derivatives have three kinds of heteroatoms as absorption centres (N, S, O) and can be used as anticorrosion compounds for protecting metals.…”

This paper addresses the preparation and characterization of protective anticorrosion silane-and polyrhodanine-based bilayer coatings on a tested electrode substrate. Polyrhodanine (pRh) coatings were electrodeposited using the cyclic voltammetry technique on glassy carbon and stainless steel substrates. Isobutyltriethoxysilane (IBTES) films were deposited by the simple dipcoating method on steel substrates and then were stored in air (''aged''). The formed novel bilayer pRh/IBTES coatings were applied on the electrode surface as moderately thin (ca. 6-8 nm thick) layers and exhibited very good adhesion to the steel substrate. The physicochemical properties of pRh, IBTES and bilayer pRh/IBTES coatings were determined with the use of electrochemical, X-ray photoelectron spectroscopy and scanning electron microscopy techniques. The bilayer coatings consisting of a conducting polymer-pRh and silane-IBTES most effectively hinder the access of pitting-causing aggressive anions (chlorides) to the surface of stainless steel and exhibit better barrier properties compared to single-component pRh and IBTES coatings.

The electrochemical study of 2‐Sulfanylidene‐1,3‐thiazolidin‐4‐one (rhodanine, R) was performed on a glassy carbon working electrode by using three methods: differential pulse voltammetry (DPV), cyclic voltammetry (CV), and linear sweep voltammetry (LSV) at rotating disk electrode voltammetry (RDE). The CV, DPV, and LSV at RDE curves for R were recorded at different concentrations in 0.1 M TBAP/CH3CN. Polymeric films were formed by successive cycling at different potentials and by controlled potential electrolysis. The film formation was proved by recording the CV curves of the chemically modified electrodes (CMEs) in transfer solutions containing ferrocene in 0.1 M TBAP/CH3CN. The obtained CMEs were used for the detection of heavy metal ions. Synthetic samples of heavy metal ions (Cd (II), Pb (II), Cu (II), Hg (II)) of concentrations between 10−7 and 10−5 M were analyzed using CMEs prepared in different conditions. The most intense signal was obtained for Pb(II) ion (estimated detection limit = 10−7 M), which shows that these CMEs can be used for Pb(II) ion detection. The ability of R to form complexes with Pb(II) ion was also tested by UV‐Vis spectrometry. The obtained results showed the formation of Pb(II)R2 as the most stable complex.
