Abstract:

Quaternary methyl di-ally ammonium salt (MDAA) was grafted on the surface of a polypropylene (PP) nonwoven using a low-temperature radio frequency discharge plasma. The graft ratio of MDAA to PP increased with the grafting temperature; at low grafting temperatures (30 or 60 °C), the graft ratio increased with the H2SO4 catalyst concentration, but at a high grafting temperature (80 °C), it was not affected, even without the use of an acid catalyst. The finished PP nonwoven exhibited excellent antibacterial activities toward Staphylococcus aureus, suggesting that plasma grafting is an effective method.
