| 摘 要： | 为了改善聚甲基丙烯酸甲酯(PMMA)人工晶状体的生物相容性和透光性, 采用CF4/O2等离子体技术修饰其表面. 通过衰减全反射红外光谱(ATR-FTIR)、X射线光电子能谱(XPS)、静态接触角(CA)测定、扫描电子显微镜(SEM)、紫外-可见近红外光谱(UV-Vis)等方法进行表征, 结果表明, 经CF4/O2等离子体处理后, PMMA表面的含氟和含氧基团增加, 其表面的亲水性增强, 生物相容性改善, 紫外光的隔离效率增大. 因此, 通过CF4/O2等离子体修饰能够有效地改善PMMA人工晶状体的性质.

| Abstract: | To improve biocompatibility and transmittance of polymethyl methacrylate intraocular lens(PMMA IOL),the surface of PMMA IOL was treated by CF4/O2 redio-frequency(RF)-plasma.The modified PMMA IOLs were characterized by the attenuated total reflectance Fourier transfer infrared spectroscopy(ATR-FTIR),X-ray photoelectron spectroscopy(XPS),the contact angle(CA) measurement,scanning electron microscopy(SEM) and ultraviolet-visible spectroscopy(UV-Vis),respectively.The results indicated that the treatment of CF4/O2 RF-plasma could make the modified PMMA IOL not only increase the contents of fluorine and oxygen,hydrophilicity and anti-ultroviolet radiation but also improve biocompatibility.Based on these results,the treatment of CF4/O2 RF-plasma is an effective method to improve the performance of PMMA IOL. |
