Preparation and Biochemical Activity of Copper-Coated Cellulose Nonwoven Fabric via Magnetron Sputtering and Alginate-Calcium Ion Complexation.

ABSTRACT: Alginate-based materials have gained significant recognition in the medical industry due to their favorable biochemical properties. As a continuation of our previous studies, we have introduced a new composite consisting of cellulose nonwoven fabric charged with a metallic copper core (CNW-Cu⁰) covered with a calcium alginate (ALG^-Ca²⁺) layer. The preparation process for these materials involved three main steps: coating the cellulose nonwoven fabric with copper via magnetron sputtering (CNW → CNW-Cu⁰), subsequent deposition with sodium alginate (CNW-Cu⁰ → CNW-Cu⁰/ALG^-Na⁺), followed by cross-linking the alginate chains with calcium ions (CNW-Cu⁰/ALG^-Na⁺ → CNW-Cu⁰
