Název v původním jazyce

Degradation of a model dye with zinc phthalocyanine sulphonamide embedded in polymer matrices

Popis výsledku v původním jazyce

Zinc phthalocyanine bearing aliphatic sulphonamide group was prepared and embedded in two polymer matrices (polypropylene, polyethylene-vinyl acetate), respectively. The composite films were evaluated for singlet oxygen production. Singlet oxygen production increased with increasing phthalocyanine concentration in both polymers. The degradation of a diketopyrrolopyrrole dye in thin layer doctor-bladed on the polymer films as well as antibacterial activity of the films were evaluated. It has been found that the polymer type had a crucial effect on the film properties. The degradation of the model dye in solid state was about four times faster with polyethylene-vinyl acetate film than polypropylene films. These films promise a broad potential for practical applications such as self-cleaning surfaces and antimicrobial protective films.
