摘要: 通过紫外光接枝和湿化学法连用在聚醚醚酮 (PEEK)表面固定上具有抑菌杀菌作用的壳聚糖。结果表明,相比未改性的PEEK表面,改性后材料表面亲水性提高;通过扫描电子显微镜和X射线光电子能谱分析证明壳聚糖成功接枝在了PEEK薄膜表面;随着壳聚糖浓度的提高,材料表面的壳聚糖接枝率增加。

Abstract: Chitosan was grafted on the surface of poly(ether ether ketone) (PEEK) by UV radiation and wet chemical method for bacteriostasis and disinfection. Compared with the unmodified PEEK, the hydrophilicity of grafted PEEK film was increased. It showed that chitosan was successfully grafted on the surface of PEEK by SEM and XPS. In addition, the degree of grafting of chitosan on the surface of the material increased with increasing chitosan concentration.
