Flexible antibacterial Zr-Cu-N thin films resistant to cracking

Popis výsledku v původním jazyce

This study investigates how the Cu concentration in Zr-Cu-N films affects the films' antibacterial capacity and mechanical properties. Zr-Cu-N films were prepared by reactive magnetron sputtering from composed Zr/Cu targets using a dual magnetron in an Ar + N2 mixture. The antibacterial capacity was modulated by the amount of Cu added to the Zr-Cu-N film. The mechanical properties were varied based on the energy delivered to the growing film by bombarding ions. It was found that it is possible to form Zr-Cu-N films with Cu concentrations GREATER-THAN OR EQUAL TO10 at. % that simultaneously exhibit (1) 100% killing efficiency for E. coli bacteria on their surfaces, and (2) (i) high hardness of about 25 GPa, (ii) high ratio H/E* GREATER-THAN OR EQUAL TO 0.1, (iii) high elastic recovery We GREATER-THAN OR EQUAL TO 60% and (iv) compressive macrostress. The Zr-Cu-N films with these parameters are flexible/antibacterial films that exhibit enhanced resistance to cracking.
