Preparation and Characterization of Plasma Treated Melt-Blown Polypropylene Nonwovens Grafted with Acrylic Acid

The melt-blown polypropylene nonwoven fabric plasma treated to graft with acrylic acid has been investigated by FTIR, SEM and Contact Angle Determinator respectively. It was found that after grafting with acrylic acid the wettability of the PP nonwoven fabric could be significantly improved from 140.9°to almost 0°in a short period of time by plasma treatment and increased to 110.6° and 133.2° after 20 days and 40 days respectively. However, the wettability of acrylic acid grafted PP nonwoven fabric could be improved to 72.9°with a permanent hydrophilic behavior.
