“…Recently, silver nitrate has been used as a photoinitiator for the preparation of PPy/clay/Ag composites by in situ ultraviolet (UV)‐induced dispersion polymerization. Mt was functionalized with silane groups to provide anchor sites for PPy/Ag composites or PPy/Ag chains directly deposited on attapulgite fiber to form PPy/attapulgite/Ag composites . In addition, using silver nitrate as a direct oxidant of Py monomer for the production of conducting PPy/Ag composites has been reported .…”

“…To the best of our knowledge, many studies have reported for the preparation of PPy/Mt and PPy/Ag composites in previous works, but only two studies have reported for the synthesis of PPy–Mt–Ag composites. Jlassi et al . revealed that PPy/Mt/Ag composites prepared by in situ UV‐induced dispersion polymerization exhibited the strong catalytic property for the reduction of methylene blue (MB) by NaBH 4 .…”

The present study demonstrates a simple approach to the formation of polypyrrole/montmorillonite/silver (PPy/Mt/Ag) composites via in situ oxidative polymerization of pyrrole (Py) in the presence of AgNO3 acting as a direct oxidant. The polymerization was performed in the presence of dodecylbenzenesulfonic acid, which acts as a stabilizing and doping agent. The morphological, structural, and thermal properties of PPy/Mt/Ag composites are discussed in detail and a possible formation mechanism is proposed. The electrical conductivities of the composites pressed at different pressing pressures were investigated using four‐probe analyzer. X‐ray diffraction, transmission electron microscopy, and scanning electron microscopy results indicated the partially exfoliated structure of the composites and Fourier transforms infrared results suggested the strong interactions between SiOSi groups in Mt and NH groups in PPy chains. The addition of Mt in the PPy polymer enhanced thermal property of the polymer. The conductivity of 1.08 S cm−1 was observed in the sample with 20 wt % Mt loading and applied pressure of 5 MPa. The composites obtained in the present study catalyze the reduction of methylene blue by sodium borohydride, achieving 92% conversion of MB to colorless within a few minutes. © 2017 Wiley Periodicals, Inc.

“…One can also undergo covalent modification of clays using, e.g. silane coupling agents . Surface and interface modification of clays via either covalent or non‐covalent routes is an important step towards materials that are suitable for many applications such as clay/polymer nanocomposites, adsorbents, anti‐corrosion layers and catalysts …”

“…Indeed, by selecting the appropriate reactive group borne by the silane one can design remarkable clay‐based systems owing to the reactivity of the silanized clays. In this way, silanized clays can be grafted with polymers, polymer nanocomposites, proteins, dyes and metal nanoparticles to name but these materials.…”

Clay/mercaptosuccinic acid hybrids were prepared through radical thiol-ene coupling between methacrylate-silanized clay and mercaptosuccinic acid. The clay surface was modified by 3-trimethoxysilylpropylmethacrylate, then mercaptosuccinic acid was clicked by ultraviolet (UV)-triggered thiol-ene addition reaction at 365 nm. Pristine and modified clays were characterized by X-ray diffraction (XRD), attenuated total reflection (ATR) and XPS. The clay/mercaptosuccinic acid material was employed as an adsorbent for the removal of Pb(II) from aqueous solutions. Kinetic studies indicated that the adsorption of Pb(II) followed the pseudo-first-order equation while the Langmuir model fitted the adsorption isotherm. The maximum adsorption was found to be 74.7 mg/g for an equilibrium time of~80 min. UV-triggered thiol-ene reaction is demonstrated to be an easy and elegant pathway for designing reactive and functional clay for environmental and other applications.

Abstract:Conducting polymers (CPs) have been widely studied to realize advanced technologies in various areas such as chemical and biosensors, catalysts, photovoltaic cells, batteries, supercapacitors, and others. In particular, hybridization of CPs with inorganic species has allowed the production of promising functional materials with improved performance in various applications. Consequently, many important studies on CPs have been carried out over the last decade, and numerous researchers remain attracted to CPs from a technological perspective. In this review, we provide a theoretical classification of fabrication techniques and a brief summary of the most recent developments in synthesis methods. We evaluate the efficacy and benefits of these methods for the preparation of pure CP nanomaterials and nanohybrids, presenting the newest trends from around the world with 205 references, most of which are from the last three years. Furthermore, we also evaluate the effects of various factors on the structures and properties of CP nanomaterials, citing a large variety of publications.
