Abstract

Effects of silver nanoparticles and fungal degradation on the weight loss and chemical composition of heat-treated poplar wood were studied. Wood blocks were impregnated with a 400 ppm nanosilver suspension under 3 bar pressure for 20 min using Lowry process (edited empty cell). Heat-treatment was carried out at 135, 160 and 185 °C. Specimens were divided into 4 groups; control, nanosilver impregnated, heat-treated and impregnated- heat treated specimens (135, 160 and 185 °C). All samples from the internal and superficial parts of the blocks were exposed to the white rot fungus Trametes versicolor. The results of heat-treated samples indicated higher amount of Klason lignin and extractives, but lower holocellulose and cellulose content. Furthermore, heat-treatment illustrated an increasing effect on the fungal resistance. For all the properties, significant difference was found between the internal and superficial test specimens. Nanosilver impregnation had an intensifying effect on the results of the heat-treatment.

Zusammenfassung

Untersucht wurde der Einfluss einer Imprägnierung mit Silber-Nanopartikeln auf den pilzbedingten Holzabbau, den Masseverlust und die chemische Zusammensetzung von thermisch behandeltem Pappelholz. Holzprüfkörper wurden mit einer 400 ppm Nanosilber-Lösung bei einem Druck von 3 bar und über eine Dauer von 20 Minuten nach dem Lowry-Verfahren imprägniert. Die Temperaturen der thermischen Behandlung betrugen 135, 160 und 185 °C. Die Prüfkörper wurden in die vier Gruppen Kontrolle, mit Nanosilber imprägnierte, thermisch behandelte sowie imprägnierte und thermisch behandelte Prüfkörper (135, 160 und 185 °C) unterteilt. Alle Proben aus dem inneren und dem oberflächennahen Bereich der Prüfkörper wurden dem Weißfäulepilz Trametes versicolor ausgesetzt. Die thermisch behandelten Prüfkörper wiesen eine höhere Menge an Klason-Lignin und Extraktstoffen auf, jedoch einen geringeren Holocellulose- und Celluloseghalt. Darüber hinaus zeigte sich eine Zunahme der Pilzresistenz aufgrund thermischer Behandlung. Bei allen Versuchen ergaben sich signifikante Unterschiede zwischen den inneren und den oberflächennahen Proben. Die Nanosilber-Imprägnierung wirkte sich positiv auf die Ergebnisse der thermischen Behandlung aus.
