“…Poly(ethyl methacrylate) (PEMA) was selected as a model functional polymer for the development of composite coatings. The selection of this polymer was based on its advanced functional properties for various applications, such as corrosion protection of metals [31], thermal [32] and electrical [33,34] energy storage, materials for packaging [35,36], biomedical composites [37], and other applications. In this investigation, huntite (Mg 3 Ca(CO 3 ) 4 platelets), halloysite (Al 2 Si 2 O 5 (OH) 4 •2H 2 O nanotubes), and submicrometre hydrotalcite (Mg 6 Al 2 (CO 3 )(OH) 16 •4H 2 O particles) were used as inorganic FRM materials of the hydroxide or carbonate type.…”

This investigation is motivated by the need for the development of polymer coatings containing inorganic flame-retardant materials (FRMs) and the replacement of toxic halogenated FRMs. A green strategy is reported for the fabrication of poly(ethyl methacrylate) (PEMA)-FRM composite coatings using a dip-coating method. The use of water-isopropanol co-solvent allows the replacement of regular toxic solvents for PEMA. The abilities to form concentrated solutions of high-molecular-mass PEMA and to disperse FRM particles in such solutions are the main factors in the fabrication of coatings using a dip-coating technique. Huntite, halloysite, and hydrotalcite are used as advanced FRMs for the fabrication of PEMA-FRM coatings. FTIR, XRD, SEM, and TGA data are used for the analysis of the microstructure and composition of PEMA-FRM coatings. PEMA and PEMA-FRM coatings provide corrosion protection of stainless steel. The ability to form laminates with different layers using a dip-coating method facilitates the fabrication of composite coatings with enhanced properties.

“…In previous literature, GO/Ag nanocomposites are synthesised by in situ method using different reducing and stabilising agent such as hydrazine hydrate and sodium borohydride. [23,24] However, these chemicals are highly toxic, and the fabrication methods are difficult. Mohammadi et al has synthesised Ag/rGO nanocomposites for higher catalytic properties using diethylene glycol (DEG) as reducing agent that is a poisonous organic compound.…”

Herein, a low-cost and eco-friendly approach is adopted for the synthesis of L-cysteine-assisted silver/reduced graphene oxide (L-cys-rGO/Ag) nanocomposites using sodium citrate as reducing agent. The morphology of graphene oxide (GO) and L-cys-rGO/Ag nanocomposites are studied by scanning electron microscope (SEM). The strong interactions of rGO/Ag with L-cysteine are established by Fourier transferred infrared (FTIR) study. The average diameter of dispersed Ag NPs is 40 to 70 nm, which is evidenced by transmission electron microscope (TEM). In the preparation of L-cys-rGO/Ag nanocomposites, both GO and L-cysteine are used as supporting and stabilising media to avoid the unexpected agglomeration in the in situ formed Ag NPs and to get high surface area in the nanocomposites. The excellent behaviour of L-cys-rGO/Ag nanocomposites acting as a heterogeneous catalyst for the conversion of 4-nitrophenol to 4-aminophenol with NaBH 4 is achieved that is due to the high adsorption of reactant on the surface rGO and more transfers of electron from rGO to Ag NPs. Beside this, Lcys-rGO/Ag nanocatalyst can be reused several times with negligible loss of catalytic efficiency. Further, the as-synthesised nanocomposites show good antioxidant behaviour.

“…Of particular importance for composite development are the biocompatibility, high chemical stability, flexibility, advanced mechanical properties, and thermal stability of this polymer [1,2]. PEMA is a low-cost polymer, which has generated significant interest for its corrosion protection of metals [3], packaging [4,5], energy storage in capacitors [6] and batteries [7,8], thermal energy storage [9], and other applications. Significant enhancement of its properties and functionality was achieved by combining PEMA with other functional materials and fabrication of composites [8][9][10].…”

Poly(ethyl methacrylate) (PEMA) is dissolved in ethanol, known to be a non-solvent for PEMA, due to the solubilizing ability of an added bile acid biosurfactant, lithocholic acid (LA). The ability to avoid traditional toxic and carcinogenic solvents is important for the fabrication of composites for biomedical applications. The formation of concentrated solutions of high molecular weight PEMA is a key factor for the film deposition using the dip coating method. PEMA films provide corrosion protection for stainless steel. Composite films are prepared, containing bioceramics, such as hydroxyapatite and silica, for biomedical applications. LA facilitates dispersion of hydroxyapatite and silica in suspensions for film deposition. Ibuprofen and tetracycline are used as model drugs for the fabrication of composite films. PEMA-nanocellulose films are successfully prepared using the dip coating method. The microstructure and composition of the films are investigated. The conceptually new approach developed in this investigation represents a versatile strategy for the fabrication of composites for biomedical and other applications, using natural biosurfactants as solubilizing and dispersing agents.
