Sklodowskiej-Curie Street 3, 90-505 Lodz, Poland. Journal Article 2019 08 18 Polylactide nonwoven was modified by poly(N,Ndimethylaminoethyl methacrylate). The surface was quaternizated with crosslinking. A two-step method was used: first spraying the polymer, then cross-linking with ethylene bromide. The modification was confirmed by infrared spectroscopy and solubility tests. The antibacterial activity of unmodified nonwoven, nonwoven with a deposited layer of PDMAEMA and nonwoven quaternized with PDMAEMA was evaluated against Escherichia coli and Staphylococcus aureus. The antibacterial results showed that these materials could achieve up to 100% efficiency.<br /><br /> http://www.itast.ir/article_92117_4692c37d92cb9a0d291670e667c6db33.pdf
