  • Behaviour of different removers on permanent anti-graffiti organic coatings
    Journal of Building Engineering, 2016
    Co-Authors: Stefano Rossi, Michele Fedel, S. Petrolli, Flavio Deflorian

    Abstract:

    Graffiti removal presents high costs in street furniture, transport and architectural facades. Considering painted metallic surfaces, the removal has to be easy and not modify the protective and the aesthetic properties. The study of the interaction between paint and remover and the effects on the anti-graffiti properties is the aim of this paper. Two kinds of polyurethane organic coatings, indicated for metallic substrates, and two different surface finishing were considered. This kind of organic coatings shows a very good corrosion properties connected with the low water uptake together a very interesting aesthetical aspect. The behaviour of methylethylketone, xylene and an aliphatic and Aromatic Solvent mixture, before and after accelerated weathering, was evaluated. MEK was proven to be particularly aggressive. The wrinkled finishing shows strong criticality.

  • exciplex fluorescence as a diagnostic probe of structure in coordination polymers of zn2 and 4 4 bipyridine containing intercalated pyrene and enclathrated Aromatic Solvent guests
    Journal of the American Chemical Society, 2007
    Co-Authors: Gregory J Mcmanus, John J Perry, Mark Perry, Brian D Wagner, Michael J Zaworotko

    Abstract:

    Coordination polymers based on Zn(II)-4,4‘-bipyridine (Zn-bipy) frameworks containing pyrene intercalated between adjacent layers and Aromatic Solvent molecules enclathrated within the framework cavities have been prepared and characterized for the first time. These compounds are highly fluorescent, and show broad, featureless emission spectra significantly red-shifted relative to pyrene monomer fluorescence; this has been assigned to pyrene-bipy exciplex emission. Single-crystal X-ray structural analysis shows that the presence of the Aromatic Solvent molecule within the cavities has a profound effect on the architecture of these frameworks:  in the case of benzene, toluene, p-xylene, and chlorobenzene, the Zn-bipy framework consists of 1-D ladders, whereas in the case of o-dichlorobenzene (the largest Solvent guest), the framework was based on a 2-D square grid. This difference in stoichiometry and architecture was also reflected in significant differences in the fluorescence of these coordination polym…
