Inhibition effect of the nano-AgCu-treated wood at different concentrations against Aspergillus niger growth on polar wood: (a) Variations of infection value of different wood surfaces with the mold growth time; (b) digital photos of different wood surfaces against mold growth after 28 days; (c) variations of anti-mold efficiency of different wood surfaces after 28-day mold growth. (d) SEM images of different wood surfaces after fungus infection; (e) variations of nano-AgCu retention on wood surface at different concentrations; (f) SEM-EDX images of the cross section of nano-AgCu-treated wood at a concentration of 1000 mg/L; (g) SEM images of the wood longitudinal surface loaded with nano-AgCu at a concentration of 1000 mg/L; (h) XPS spectra of nano-AgCu particles; (i) XRD patterns of CK wood and the nano-AgCu (at a concentration of 1000 mg/L) loaded wood surface.
