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.

在等离子体基氟(F)和银(Ag)双离子注入沉积聚甲基丙烯酸甲酯(PMMA)的表面改性中，F+Ag注入沉积的PMMA表面形成了碳氟化银沉积层，接触角显著增大。在刷磨试验中，经过6万次刷牙后，改性聚甲基丙烯酸甲酯的接触角仍保持在表面存在F和Ag离子的状态。此外，采用ATP发光法进行抗菌试验，发现F和Ag双离子的存在对细菌生长有明显的抑制作用。这些结果表明，氟和银的双离子注入和沉积可以抑制丙烯酸酯医疗和牙科设备的细菌黏附和抗菌性能。
