| Research Abstract |
In the surface modification of polymethyl methacrylate (PMMA) by using plasma-based fluorine (F) and silver (Ag) dual-ion implantation & deposition, F+Ag implanted-deposited PMMA has formed carbon-fluoride and Ag-deposited layer on the surface and contact angle of that was significantly increased. After 60,000 brushing strokes in the brushing abrasion test, the contact angle of the modified PMMA remained to present F and Ag ions on the surface. In addition, the presence of F and Ag dual-ion was found to inhibit bacterial growth significantly by the antibacterial test using ATP luminescence method. These results suggest that fluorine and silver dual-ion implantation and deposition can provide inhibition of bacterial adhesion and antibacterial properties to acrylic medical and dental devices.
