Perfluoropolyethers as superhydrophobizing agents for carbon-based surfaces of fuel cell gas diffusion layers

Navarrini W., Sansotera M., Diamanti M.V., Pedeferri MP., Gola M., Dotelli G., Politecnico di Milano, IT

Perfluoropolyether (PFPE) peroxide has been employed in the functionalization of conductive carbon-based materials to confer them the highly hydrophobic surface properties of the perfluorinated materials. The thermal decomposition of a linear PFPE peroxide produced PFPE [...]

Advanced oxidation processes for water purification: compact vs nanoporous anodic TiO2

Piazza V., Diamanti M.V., Mazare A., Pedeferri MP., Schmuki P., Politecnico di Milano, IT

In the last years, research on TiO2 engineering has been dedicated mostly to thin films for environmental and energetic applications, such as advanced oxidation processes for water purification and dye-sensitized solar cells. Anodic oxidation can [...]

Self-cleaning ability and cooling effect of TiO2-containing mortars

Diamanti M.V., Paolini R., Zinzi M., Ormellese M., Fiori M., Pedeferri MP., Politecnico di Milano, IT

This work focuses on the characterization of a self-cleaning and photocatalytic system for building façades, aimed at improving urban surfaces and the surrounding air quality, and decreasing energy consumption. Mortars containing anatase TiO2 nanopowders were [...]

C-AFM as a means to identify heterogeneities at the nanoscale in thin anodic TiO2 films

Diamanti M.V., Souier T., Chiesa M., Pedeferri MP., Politecnico di Milano, IT

The anodic oxidation of titanium allows the obtaining of an oxide layer with thickness, color, homogeneity and insulating properties that depend on the process parameters. TiO2 thin films have been studied mostly to derive information [...]

TiO2-based photocatalytic and antimicrobial coatings: comparison between sol-gel and electrodeposited silver/TiO2 nano-composites

Diamanti M.V., Magagnin L., Del Curto B., Candiani G., Pedeferri MP., Politecnico di Milano, IT

Among possible ways to improve air quality in urban atmospheres, the use of nanostructured TiO2 films as photocatalysts is an excellent way to mitigate the problem, although it cannot offer a complete solution. TiO2 also [...]
