Abstract

Two uracil-based antimicrobial azo disperse dyes were synthesized using 6-aminouracil and 6-amino-1,3-dimethyluracil as diazo components, and they were incorporated to the backbone of polyurethane to synthesize antimicrobial polyurethane. The chemical structures of the synthesized dyes and polyurethanes were confirmed through FT-IR and 1H-NMR analysis, and their molecular weight, contact angle and thermal degradation were examined using GPC, TGA, contact angle measurement device, respectively. The fibrous membrane structure of the electro-spun polyurethane membranes were confirmed by FE-SEM, and their antibacterial test results showed excellent antimicrobial activity against Staphylococcus aureus and Escherichia coli. However, the color intensity of polyurethane containing a uracilazo dye moiety in its backbone was found to be poor due to its inherently low molar absorption coefficient.
