Organic dyes such as methyl orange (MO) and methylene blue (MB) are widely used in different industries and have become one of the leading emerging water contaminants. The purpose of the current research is to develop new polymer nanocomposite filters for the effective elimination of the dyes, which are non-biodegradable and not efficiently removed by traditional treatment methods. New padded and covered filters were produced applying polystyrene-acrylic/ZnO nanocomposite on the polyester surface by blade coating and one-bath pad methods. Principal results determined by SEM analysis confirm that functionalised layer can create unprecedented function of filter textile material depending on the way of treatment. Due to the modification, the surface area increased from 5.9 for untreated polyester to 85.2 (padded), 44.6 (covered) m2/g. The measured pore size of produced filters is around 3.4 nm, which corresponds to the mesoporous structure. Our study reported effective filters with the rate of MB and MO removal efficiencies up to 60%. Moreover, a colourless reduced form of MB—leuco-methylene blue (LMB) could be created. The functionalised layer of the developed filters through hydrogen bonding between the –OH groups of styrene-acrylic molecules and the –N(CH3)2 groups on LMB can stabilise LMB.

“…One of the main issues regarding NP immobilization is their low attachment to the supporting material. ,, Thus, the stability of such systems is low, and it is not possible to achieve high reusability . In the last few years, there have been reports on polymer nanocomposites with photocatalytic activity and high reusability. ,− Therefore, they are perspective materials for these applications, which combine the characteristics of nanomaterials with high durability, flexibility, chemical and mechanical stability, low weight, and low price of polymer materials . Among different polymers, poly(methyl methacrylate) (PMMA) has shown to be very suitable for this application as it is inexpensive, has high chemical and mechanical stability, and, what is most important, is compatible with food and drinks.…”

In the last decades, water pollution from different industries has been one of the largest environmental issues. Many efforts have been made to develop technologies to remove toxic pollutants from the contaminated waters, which are direct threats to the aquatic environment and human health. Among different technologies, heterogeneous catalysis has shown to be very effective for water purification. The main issue regarding this method is the water recovery after the treatment, which is a very expensive and laborious procedure but can be addressed by the immobilization of photocatalytic particles on the support material. Here, we present efficient and green technology for water purification based on ZnO/SnO 2 -poly(methyl methacrylate) (PMMA) nanocomposite foils utilizing superior photocatalytic properties of coupled ZnO and SnO 2 photocatalysts. We investigated the influence of the ZnO/SnO 2 nanoparticle concentration on the removal efficiency of methylene blue dye and found exceptional removal efficiency for even very low ZnO/SnO 2 nanoparticle loadings. The investigated foils were found to be highly reusable, with no change in performance after five successive usages. The composition, optical properties, surface morphology, and surface roughness of the foils were characterized by X-ray diffraction, UV−vis spectroscopy, scanning electron microscopy, and atomic force microscopy. The thermal measurements performed with differential scanning calorimetry suggested the reinforcement effect of ZnO/SnO 2 nanoparticles on the PMMA matrix, which is essential for practical applications of the foils.

“…8 Polymers are macromolecules, which are widely distributed in nature and perform several functions in everyday life. Polymers can be divided into two main categories, e.g., (I) bio-based polymers such as chitin, 9 CS, 10 silk fibroin, 11 keratin, 12 starch, 13 etc., and (II) synthetic polymers such as polyethylene, 14 polyethylene terephthalate, 15 polystyrene, 16 and GMA, 17 etc. Bio-based polymers have a non-toxic, biodegradable, economical, and environmentally friendly nature.…”
