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.
To improve biocompatibility and transmittance of polymethyI 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-I^HR）, 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.
