Název v původním jazyce

Photodegradation and chemical grafting of PEEK and PET foils for antibacterial activity

Popis výsledku v původním jazyce

The functionalization of polymers for an antibacterial effect is widely investigated for possible use in industry, medicine or households. In contrast to previously published approaches based on piranha solutions or plasma activation, we present an inexpensive method to create the antibacterial surfaces on polyether ether ketone (PEEK) and polyethylene terephthalate (PET). Polymers were firstly exposed to UV light of 254 nm wavelength and then grafted with alanine, leucine or curcumin. Surface properties of the prepared composites were studied at individual modification steps. Samples were tested for antibacterial effect against E. coli and S. epidermidis. Grafting of amino acids exhibited the greatest reduction of the bacterial colonies for E. coli and curcumin grafting for S. epidermidis.
