his study aims to compare the biological resistance of paint materials which contain different resin types (i.e., acrylic
vs. polyvinyl acetate) and resin percentages (i.e. 20%, 30% and 40%) before and after nanometal treatment, as well as to
explore the fungicidal effect of nanometals (i.e., Ag, Cu and Zn) to improve fungal resistance of paints. Six tested green paints
are paints-A (20% acrylic resin), paint-B (30% acrylic resin), paint-C (20% polyvinyl acetate resin), paint-D (30% polyvinyl
acetate resin), paint-E (40% acrylic resin) and paint-F (40% polyvinyl acetate resin), respectively. The
Aspergillus brasiliensis
or
Penicillium funiculosum
was inoculated on each sample and their growth was visually evaluated according to ASTM G21-
09. In general, fungi could grow on paints no matter what kind of resin content they have. Paints with highest resin level
showed obvious fungicidal ability even without treatment of nanometals. All test nanometals in this study helped improve the
resistance of fungal growth on test paints except for the paints with 40% resin. The impact among various nanometal tested
did not differ much in terms of final speed growth level. Fungal growth of
Penicillium
was a bit stronger than
Aspergillus
for
each test under the same conditions. In the future, studies on more fungal species and combination of nanometals with other
fungicidal agents (i.e., TiO
2
) may be helpful finding the most efficient fungicidal additive with lower concentration, stronger
fungicidal effect and less environmental impact.
Biography
Chi-Chi Lin has completed his PhD from The University of Texas at Austin. He is currently a Professor at National University of Kaohsiung in Taiwan. His research
interests focus on emissions from various building materials and associated reactions between ozone and building materials, as well as the improvement of indoor
air quality. He has published more than 20 papers in reputed journals.
