Abstract
The growing concern about environmental pollution and its side effects on human health has attracted the attention of the scientific and industrial communities. The development of functional tissues capable of reducing or eliminating organic compounds and/or pathogenic microorganisms can be a step forward in improving human and environmental well-being. This class of materials includes anti-odor, self-cleaning, UV protection, hydrophobicity and antibacterial fabrics.
12th grade Chemistry students, working in partnership with the Department of Chemical Engineering of the Faculty of Engineering of the University of Porto, used the Project-based learning methodology to develop a research project on light activated surface cleaning.
The project consists in impregnating cotton and polyester with titanium dioxide (TiO2) and their use as functional fabrics for the degradation and model pollutants (dyes, caffeine). The characterization of the functional fabrics is followed by electron microscopy, contact angle determination and solid UV-vis spectroscopy. The efficiency of the materials is assessed by UV-vis spectroscopy.
Keywords. Functional fabrics, Photocatalysis; Project-based learning; Surface cleaning.
