“…PAK was synthesized in a high yield by polymerizing terephthaldhyde with 2,5-hexanedione in a basic ethanolic solution using an aldol condensation reaction (34)(35)(36)(37)(38) (Scheme 1). FT-IR, UV and uorescence behavior, solubility, X-ray diffraction analysis, SEM morphology, thermal behavior, surface area, and GCmass spectroscopy were utilized to characterize the polymer structure.…”

This research aims to create an alternating polyketone with the advantage of having its cationic groups in one and four alternating places for increased functionality. Simple condensation polymerization between terephthaldehyde and 2,5-hexane dione yielded a new polyarylidene ketone (PAK). Fourier-transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), X-ray diffraction, UV-Visible absorbance, fluorescence, and SEM studies were used to assess the physicochemical properties of the resultant polymer. The results demonstrate that the polymer is amorphous, has good thermal stability, and emits a red color. It can also be utilized as a dye adsorbent in an aqueous solution, with remarkable adsorption selectivity for the cationic dye methylene blue (MB). The effectiveness of PAK as an adsorbent was calculated as a function of pH, dosage, and initial dye concentration; the highest dye removal percentage of 96% was achieved at pH 10, 50 mg dosage and initial dye concentration of 20 ppm. The study of kinetics and isotherms was also carried out. The pseudo-second-order model was more adapted to the kinetic data, while the Freundlich and Langmuir models were better suited to the PAK equilibrium data. According to the kinetics and isotherms analyses, the adsorption behavior was a favorable chemisorption process. The findings of this study suggest that PAK could be used as an adsorption filter for MB dyeing wastewater decolorization. It also has excellent metal ion removal capabilities with various metals (Zn2+, Cu2+, Ni2+, Co2+, Cd2+, and Fe3+). PAK is selective for Fe (III) and Cu (II); the polymers' ion adsorption is not based on ion exchange but on chelating process.

“…Therefore, researchers proposed to use nano inorganic materials in conjunction with CPS to improve the corrosion inhibition ability of metal materials. Aly et al (2019b) prepared cycloalkanone nano clay CPS composites by in-situ polymerization, and compared them with CPS polymers without nano clay. The results show that CPS modified by cyclohexanone has better shielding and protection ability, and its corrosion inhibition rate is as high as 95.9%, indicating that increasing the molecular weight of the polymer (the larger the molecular weight is, the larger the metal area can be covered) or using modified nano clay can effectively enhance the corrosion inhibition ability of CPS.…”

The use of corrosion inhibitors can effectively avoid the corrosion of metals and alloys, but the conventional organic/inorganic corrosion inhibitors have certain toxic and side effects and environmental pollution problems (including some expensive toxic reagents and catalysts), prompting researchers to turn their attention to the research of water-soluble polymer corrosion inhibitors with green environment friendly and low pollution. This paper reviews the action mechanism of polymer inhibitors, the research status of natural polymer inhibitors (chitosan-based inhibitors, cellulose and its derivatives inhibitors, other carbohydrate inhibitors, protein inhibitors) and synthetic polymer inhibitors (epoxy resin inhibitors, polyethylene glycol inhibitors, conductive polymer inhibitors), The purpose is to provide some reference for the development of eco-friendly metal coatings.

“…Peeling the stacked nanoclay into individual nanoclay layers is an important key in improving oxygen barrier performance, and the individual nanoclay layers can be uniformly dispersed in the PP matrix to form a tortuous path that inhibits gas diffusion. Recently, techniques have been applied to fabricate polymer/nanoclay nanocomposites by dispersing nanoclays into polymers by methods such as solution casting using biomimetic [ 19 ], in-situ polymerization [ 20 ], layer by layer coating [ 21 ], and melt mixing [ 22 , 23 , 24 ].…”

Polypropylene (PP) has poor oxygen barrier properties, therefore it is manufactured in a multi-layer structure with other plastics and metals, and has been widely used as a packaging material in various industries from food and beverage to pharmaceuticals. However, multi-layered packaging materials are generally low in recyclability and cause serious environmental pollution, therefore we have faced the challenge of improving the oxygen barrier performance as a uni-material. In this work, PP/nanoclay nanocomposites were prepared at nanoclay contents ranging from 0.8 to 6.4 wt% by the biaxial stretching method, performed through a sequential stretching method. It was observed that, as the draw ratio increased, the behavior of the agglomerates of the nanoclay located in the PP matrix changed and the nanoclay was dispersed along the second stretching direction. Oxygen barrier properties of PP/nanoclay nanocomposites are clearly improved due to this dispersion effect. As the biaxial stretching ratio and the content of nanoclay increased, the oxygen permeability value of the PP/nanoclay nanocomposite decreased to 43.5 cc·mm/m2·day·atm, which was reduced by about 64% compared to PP. Moreover, even when the relative humidity was increased from 0% to 90%, the oxygen permeability values remained almost the same without quality deterioration. Besides these properties, we also found that the mechanical and thermal properties were also improved. The biaxially-stretched PP/nanoclay nanocomposite fabricated in this study is a potential candidate for the replacement of the multi-layered packaging material used in the packaging fields.
