Effect of Titanium-Dioxide-Enriched Nanotextiles on Cementitious Composite Exposed to Severe Environmental Conditions

Abstract:

Photocatalytic cement containing titanium dioxide nanoparticles (N-TiO₂) is commercially available for some 10 years already, but its wider utilization is limited by economic aspects. A new approach to implanting N-TiO₂ into surface of cementitious composite exposed to severe environmental conditions was investigated. Polyvinyl alcohol (PVA) nanotextile containing N-TiO₂ was prepared on Nanospider device. Photocatalytic properties of specimens made from ordinary white cement with surface covered by PVA nanotextile containing N-TiO₂ were compared to the properties of reference samples made from ordinary white cement and samples made from commercially available photocatalytic cement. Although the PVA nanotextile containing N-TiO₂ was not found to be a prospective solution for photocatalytic finishing in this stage of research, the idea of treating concrete surfaces with enriched nanotextiles was examined and will be further pursued as a very promising research topic.
