THE CURRENT STATE OF KNOWLEDGE IN THE FIELD OF THE USE OF SELECTED NANOSYSTEMS IN HERITAGE PRESERVATION - NANOTEXTILES AS BIOCIDAL PROTECTION OF HISTORIC WOOD

摘要

The awareness of the need to protect wooden members dates back to the Middle Ages when the most common material for the protection of wood was oxblood. At present, there is a huge variety of biocidal chemical agents for wood protection available (such as Lignofix, Bochemit). Nanotextiles represent a novel method of enhanced biocidal protection of historic wood which has been intensively verified at the Faculty of Civil Engineering, CTU in Prague within the NAKI DG16P02M055 research. The paper will present partial results of experimental research into the effects of selected nanotextiles on the surface of historic wood applied for the purpose of biocidal protection. The research included the verification of the efficiency of nanotextiles without dopants and with dopants of Ag and TiO2 nanoparticles. Surprisingly, a higher biocidal efficiency of nanotextiles without dopants was reached than in the case of nanotextiles with dopants.
