One-Pot Synthesis of Copper Iodide-Polypyrrole Nanocomposites

Abstract

A novel one-pot chemical synthesis of functional copper iodide-polypyrrole composites, CuI-PPy, has been proposed. The fabrication process allows the formation of nanodimensional metal salt/polymer hybrid structures in a fully controlled time- and concentration-dependent manner. The impact of certain experimental conditions, viz., duration of synthesis, sequence of component addition and concentrations of the intact reagents on the structure, dimensionality and yield of the end-product was evaluated in detail. More specifically, the amount of marshite CuI within the hybrid composite can be ranged from 60 to 90 wt.%, depending on synthetic conditions (type and concentration of components, process duration). In addition, the conditions allowing the synthesis of nano-sized CuI distributed inside the polypyrrole matrix were found. A high morphological stability and reproducibility of the synthesized nanodimensional metal-polymer hybrid materials were approved. Finally, the electrochemical activity of the formed composites was verified by cyclic voltammetry studies. The stability of CuI-PPy composite deposited on the electrodes was strongly affected by the applied anodic limit. The proposed one-pot synthesis of the hybrid nanodimensional copper iodide-polypyrrole composites is highly innovative, meets the requirements of Green Chemistry and is potentially useful for future biosensor development. In addition, this study is expected to generally contribute to the knowledge on the hybrid nano-based composites with tailored properties.

Versatile, Rapid, and Plasma‐Assisted Synthesis of Cuprous Halide Composites at Room Temperature and Pressure

“…The UV-vis absorption measurements of the films, and electrical properties measured by four point probe (see Table S6, Supporting Information) both suggest that the films have potential for use in a number of device applications, such as the CuBr in electroluminescence, [38] the CuCl in a pseudocapacitor, [39] and the CuCl 0.1 I 0.9 in electrochemical sensing. [26] Finally, we note that in our previous work, the products synthesized were morphologically and chemically different from those produced in this work. [29] We saw no evidence of any crystalline products being formed.…”

“…[25] Similarly, a polypyrrole/CuI composite film synthesized through a one-pot approach, demonstrated electrochemical sensing properties. [26] Composite films comprising inorganic nanoparticles within a polymer matrix provide advantages for certain applications, where their contrasting and/or complementary properties can create synergistic benefits. [27] Here, we demonstrate a versatile, single-step approach to synthesizing an array of CuX composite films.…”

Aging and degradation of transparent copper iodide thin film electrodes for functional electronic devices

“…Transparent CuJ copper iodide thin-film electrodes are widely used in various optoelectronic devices, such as solar cells, electroluminescent displays, touch screens, multifunctional photoconverters, etc. Their advantages are high transparency, as CuJ absorbs light in a limited range of wavelengths, allowing them to transmit visible light, making them ideal for transparent devices, low cost, as CuJ is an inexpensive material, making it cost-effective for mass production, ease of fabrication, as CuJ can be easily deposited on various substrates using simple film deposition methods such as vacuum deposition and magnetron sputtering (Frey & Khan, 2015;Davydenko et al, 2016;Konakov at al., 2021).…”
