Development of modified protective lime coating systems with increased resistance to microbiological growth
Provider: Univerzita Pardubice
Programme: Studentská grantová soutěž
Implementation period: 01.01.20 - 31.12.21
Workplace:
Fakulta restaurování - FR
Investigator: Bayer Karol
Description:
The project aims to prepare and systematically test lime coating systems modified with nanomaterials that increase resistance to microbiological settlement. For this purpose, the modification of the coatings with nano-titanium white will be tested. The self-cleaning effect for different types of materials has been known for a long time in nano-titanium white. However, the possibility of utilizing the photoactive properties of nano-titanium white in combination with lime coatings has not been tested. Not only the efficiency of these coatings will be tested, but also their composition will be optimized and the basic properties (adhesion, porosity, microstructure, water absorption, vapor permeability, color) will be evaluated on a series of samples after application on a porous limestone substrate. At the same time, the possibility of improving adhesion and extending the service life of a given type of coatings will be tested by treating the substrate with a primer based on lime alcohol nanosuspensions. The tests will be performed under laboratory conditions and also as a field off-road test monitored for a longer period of time.
