The Biocidal Protection of Timber by Polyvinyl Alcohol Nanofiber Textiles Doped by Silver Ions
Original language description
The crawl space is a popular type of building foundations as in Europe as in Czech Republic. The bottom of building is the most predisposed space for biodeterioration and this space is often very difficult accessible for supplementary protection or for repairing. For that reason, there was studied the application of biocidal nanofiber textile on the material which is common used in this space - solid spruce wood. In the present paper there was evaluated the antifungal efficiency of polyvinyl alcohol nanofiber textiles doped by silver ions. The polyvinyl alcohol nanofiber textile doped by silver ions was fabricated by electrospinning on Nanospider LB 500. The final theoretical concentration of silver ions was 1 % in nanofibers. The nanofiber textiles were applied by enveloping of timber specimens and the samples were placed on inoculated agar plate. There were used two different ways of stabilization of nanofiber textile (glutaraldehyde vapor or leaching and heat treatment to get water insolubility) and the procedures sequence for specimens preparing (packing of specimens before and after stabilization). The efficiency of applied nanofiber textiles was measured as a percentage fungi coverage. The best protection was showed by used the nanotextile which was stabilized by glutaraldehyde vapor and the packing of sample was made before the stabilization process.
