| 目的 提高 PET 材料的表面亲水性。 方法 氯化亚锡与 PET 共混成膜后,采用共混接枝法,在共混膜表面接枝氨基化改性的纳米二氧化硅,制备出强亲水的 PET 材料。 采用静态接触角、傅里叶变换红外光谱仪、原子力显微镜测试手段对 PET 材料表面进行表征。 结果 氨基化改性的纳米二氧化硅能够成功接枝在氯化亚锡与 PET 共混材料表面。 当氯化亚锡质量分数为 0. 3% 时,共混膜接触角由 98°下降到 74. 5°。 共混膜接枝氨基化改性的纳米二氧化硅溶液 20 h 时,PET 材料表面接触角由 74. 5°下降到7. 8°,亲水性得到了极大提高。 接枝膜浸泡于蒸馏水 10 d 后,PET 材料表面接触角由 7. 8°上升至 34. 9°。结论 氯化亚锡与 PET 材料共混,接枝氨基化改性的纳米二氧化硅后极大地提高了 PET 材料表面的亲水性。 |

| Objective To improve the surface hydrophilicity of PET materials. Methods In this paper, highly hydrophilic PET materials were prepared by blending with SnCl2 and then grafting amination-modified nano-silica on the surface of the blended film. The surface properties of PET materials were characterized by static contact angle measurement, Fourier transformed infrared spec- troscopy and atomic force microscopy. Results The results showed that amination-modified nano-silica was successfully grafted on the surface of the SnCl2 / PET blended materials. When the content of SnCl2 was 0. 3% in PET materials, the surface contact angle of blending membrane dropped from 98° to 74. 5°. The surface contact angle of PET materials dropped from 74. 5° to 7. 8° after the blending membrane was grafted with amination-modified nano-silica for 20 h, and the hydrophilicity was increased dramatically. The surface contact angle of PET materials increased from 7. 8° to 34. 9°after the grafted membrane was soaked in distilled water for 10 d. Conclusion The surface hydrophilicity of PET materials was improved greatly by blending with SnCl2 and then grafting amina- tion-modified nano-silica. |
