概要 | In this study, the antibacterial and antiviral properties of fibre network functionalised materials with tannic acid and condensed tannins derived from German spruce bark extract were demonstrated. First, tannins were extracted from the inner bark of Norway spruce using a pressurised hot water extraction method and a sugar-free extract was obtained after generation. Lignocellulose handsheets were produced and impregnated with the extract. The antibacterial and antiviral enforcement of the handsheets was evaluated using bioluminescent bacterial strains, etc. The binding within the fibre matrix was investigated by FTIR-ATR spectroscopy; the distribution of tannins in the fibre network was measured and visualised using ToF-SIMS and digital microscopy. The results demonstrated that immobilisation of tannin-rich extracts in the fibre matrix exhibited antibacterial and antiviral properties. |
