The role of roughness and porosity on the self-cleaning and anti-biofouling efficiency of TiO2-Cu and TiO2-Ag nanocoatings applied on fired bricks

Experimental curves were overlapped to analytical model calculated by Avrami's law, and its validity was confirmed where latency time could be observed. Whereas no latency time was detected, that is a very fast adhesion of algal cells occurred, the experimental curves were modelled by using a four parametric logistic model that was able to describe numerically the biofouling process.
