Due to their trimethylammonium functional groups, the host materials alone exhibited an affinity to anionic water contaminants and antimicrobial properties. The introduction of such particles as CuO, Cu2O, metallic Cu, CuO\/FeO(OH), Cu4O3, Cu(OH)2, Cu4(OH)6SO4, Cu2(OH)3Cl increased these properties and demonstrated new properties. The composites were obtained unconventionally, in ambient conditions, using eco-friendly reagents. Alternative synthesis methods were compared and optimized, as a result of which a new group of hybrid ion exchangers was created (HIXs) containing 3.5\u201312.5 wt% of Cu. As the arrangement of the inorganic phase in the resin matrix was atypical, i.e., close to the surface of the beads, the obtained HIXs exhibited excellent kinetic properties in the process of oxidation and adsorption of As(III), as well as catalytic properties for the synthesis of triazoles via click reaction, and also antimicrobial properties in relation to Gram-positive Enterococcus faecalis and Gram-negative Pseudomonas aeruginosa and Escherichia coli, preventing biofilm formation. Using thermogravimetry, the effect of the inorganic phase on decomposition of the polymeric phase was evaluated for the first time and comprehensively, confirming the relationship and finding numerous regularities. It was also found that, depending on the oxidation state (CuO, Cu2O, Cu), copper-containing particles affected the textural properties of the polymeric phase endowing a tighter structure, limiting the porosity and reducing the affinity for water.<\/jats:p>","DOI":"10.3390\/polym15173606","type":"journal-article","created":{"date-parts":[[2023,8,30]],"date-time":"2023-08-30T10:09:49Z","timestamp":1693390189000},"page":"3606","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Multifunctional Composite Materials Based on Anion Exchangers Modified with Copper Compounds\u2014A Review of Their Synthesis Methods, Characteristics and Applications"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6696-0205","authenticated-orcid":false,"given":"El\u017cbieta","family":"Kocio\u0142ek-Balawejder","sequence":"first","affiliation":[{"name":"Department of Chemical Technology, Wroclaw University of Economics and Business, 53-345 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ewa","family":"Stanis\u0142awska","sequence":"additional","affiliation":[{"name":"Department of Chemical Technology, Wroclaw University of Economics and Business, 53-345 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Igor","family":"Mucha","sequence":"additional","affiliation":[{"name":"Department of Basic Chemical Sciences, Wroclaw Medical University, 50-556 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3590-0781","authenticated-orcid":false,"given":"Daniel","family":"Oci\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Chemical Technology, Wroclaw University of Economics and Business, 53-345 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2405-3433","authenticated-orcid":false,"given":"Irena","family":"Jacukowicz-Sobala","sequence":"additional","affiliation":[{"name":"Department of Chemical Technology, Wroclaw University of Economics and Business, 53-345 Wroc\u0142aw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"21351","DOI":"10.1016\/j.ijhydene.2019.06.184","article-title":"Cu2O as an emerging photocathode for solar water splitting\u2014A status review","volume":"44","author":"Bagal","year":"2019","journal-title":"Int.
