Multifunctional Composite Materials Based on Anion Exchangers Modified with Copper Compounds-A Review of Their Synthesis Methods, Characteristics and Applications.

As copper and its compounds are of fundamental importance for the development of innovative materials, the synthesis of composites intended for water purification was undertaken in which submicron copper containing particles were dispersed within the matrix of a strongly basic anion exchanger, with a macroporous and gel-like structure. 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, CuO, metallic Cu, CuO/FeO(OH), CuO, Cu(OH), Cu(OH)SO, Cu(OH)Cl increased these properties and demonstrated new properties.

Copper Rich Composite Materials Based on Carboxylic Cation Exchangers and Their Thermal Transformation.

The effect of a cupric deposit (Cu, CuO) on the thermal decomposition of carboxylic cation exchangers (CCEs) is not known, and such studies may have practical significance. CCEs have a very high ion exchange capacity, so an exceptionally large amount of CuO (which is a catalyst) can be precipitated inside them. Two CCEs, macroreticular (Amberlite IRC50) and gel-like (Amberlite IRC86), served as a polymeric support to obtain copper-rich hybrid ion exchangers.

Weakly Hydrated Anion Exchangers Doped with CuO and Cu Particles-Thermogravimetric Studies.

Hybrid ion exchangers (HIXs) containing fine CuO and Cu particles were subjected to thermal analysis in order to determine their hygroscopic water content (with regard to their anomalously low porosity) and to determine the effect of the oxidation state of the copper atom in the deposit on the thermal properties of composite materials. Commercially available anion exchangers, Amberlite IRA 900Cl (macroreticular, M) and Amberlite IRA 402OH (gel-like, G), were used as supporting materials. M/CuO, G/CuO, M/Cu and G/Cu, containing 4.
