In this work, we describe for the first time the synthesis of a hydrogel with iron oxide nanoparticles, uniformly distributed in its structure on a polyamide fabric by surface initiated photopolymerization. The type of outgoing iron ions Fe(II), Fe(III), and the combination between them influences the properties of the iron oxide particles and the obtained composite materials (PAF2, PAF3, and PAF32). All composite materials have been investigated as catalysts in heterogeneous Fenton process for treating real industrial wastewater after dyeing of cotton fabric with reactive dye Drimarene K-7B. Different conditions on the degradation of this dye have been investigated. The best result for discoloration has been obtained with PAF2 at concentration 9.4 g L −1 and pH = 2.2 in the presence of H 2 O 2 (93.3 mmol L −1 , where 78% of dye was degraded for 24 h and 90.5%-for 48 h. The high salinity of wastewaters, typical for dyeing with reactive dyes favors discoloration, while surface-active agents hinder the process. The obtained material is reusable and is more effective in less polluted water solutions. It has been found that the composite material can be used repeatedly.

The functional characteristics of a new eosin dye with biocidal quaternary ammonium group (E) were studied in aqueous solution and in organic solvents of different polarity. The spectral properties depend on the nature and polarity of the respective solvents. The antimicrobial activity of compound E has been tested in vitro against Gram-negative bacteria (Escherichia coli, Acinetobacter johnsoni and Pseudomonas aeruginosa), Gram-positive bacteria (Sarcina lutea and Bacillus cereus) and the antifungal activity was tested against the yeasts Candida lipolytica in solution and after treated on cotton fabric. Broth dilution test has been used for quantitative evaluation of the antimicrobial activity of compound E against the model strains. The ability of compound E to inhibit the growth of model Gram-negative P. aeruginosa strain was assessed after 16 h of incubation in presence and absence of light. These experiments were conducted in planktonic format in solution and on cotton fabric. The results suggest that the new compound is effective in treating the relevant pathogens with better results being obtained by irradiation with light. In this case the quaternary ammonium group promotes the binding of eosin Y moiety to the bacterial cell wall thus accelerating bacterial photo inactivation.

The photoinduced polymerization of monomers is currently an essential tool in various industries. The photopolymerization process plays an increasingly important role in biomedical applications. It is especially used in the production of dental composites. It also exhibits unique properties, such as a short time of polymerization of composites (up to a few seconds), low energy consumption, and spatial resolution (polymerization only in irradiated areas). This paper describes a short overview of the history and classification of different typical monomers and photoinitiating systems such as bimolecular photoinitiator system containing camphorquinone and aromatic amine, 1-phenyl-1,2-propanedione, phosphine derivatives, germanium derivatives, hexaarylbiimidazole derivatives, silane-based derivatives and thioxanthone derivatives used in the production of dental composites with their limitations and disadvantages. Moreover, this article represents the challenges faced when using the latest inventions in the field of dental materials, with a particular focus on photoinitiating systems based on iodonium salts. The beneficial properties of dental composites cured using initiation systems based on iodonium salts have been demonstrated.
