摘要：

为改善聚四氟乙烯纤维的表面性能,赋予其亲水性,利用多巴胺氧化自聚合的特性,采用多巴胺浸渍改性处理聚四氟乙烯纤维,借助扫描电子显微镜、原子力显微镜、傅里叶红外光谱仪、静态水接触角测量仪测试改性后纤维的表面特性及化学组成,研究改性后纤维在不同溶液中的洗脱吸光度,分析纤维与多巴胺的结合牢度。结果表明:随着浸渍时间的延长,聚四氟乙烯纤维表面的聚多巴胺层愈加致密;当处理时间达24 h时,纤维的静态水接触角由120 °减小到69°;继续延长处理时间,接触角无明显变化;改性后的聚四氟乙烯纤维表面引入—COOH、—NH2等亲水基团,纤维亲水性明显提高;纤维与聚多巴胺结合稳定,牢度良好。

关键词: 聚四氟乙烯, 多巴胺, 亲水性, 结合牢度

Abstract:

In order to improve the surface performance in hydrophilicity of polytetrafluoroethylene fibers , dopamine was employed to modify polytetrafluoroethylene fibers by oxidation self-polymerization. The effect of different treatment time for modifying polytetrafluoroethylene fibers was analyzed. Scanning electron microscopy, atomic force microscopy, Fourier transform infrared spectrometer and water contact angle (WCA) tester were employed to analyze the surface morphology and the chemical structures of the modified polytetrafluoroethylene fibers. The binding fastness of the fibers to dopamine was analyzed by testing the elution absorbance of the modified fibers in different solutions.The results show that a dense layer of polydopamine is formed on polytetrafluoroethylene fibers with the increase in modification time, and the WCA decreases gradually from 120° to the platform of 69° when the treatment time is up to 24 h. The modified polytetrafluoroethylene fibers introduces hydrophilic groups such as —COOH and —NH2, and the hydrophilicity of the fibers are improved obviously. The binding fastness between fiber and polydopamine is stable.

Key words: polytetrafluoroethylene, dopamine, hydrophilicity, binding fastness
