| 中文摘要: |
| 本研究设计和合成铜/镍配位型咪唑离子液体（分别记为IL/Cu和IL/Ni），并对其性能进行研究。采用接枝聚合策略，成功合成了多功能的纤维素水凝胶，分别命名为CH-CTA-PIL/Cu和CH-CTA-PIL/Ni。结果表明，所得水凝胶在808 nm近红外激光照射下展现出优异的光热响应性能，温升可达27 ℃，并具有良好的热稳定性。抗菌性能测试表明，该水凝胶在光照和非光照环境下均能有效抑制金黄色葡萄球菌和大肠杆菌的生长；在近红外激光照射条件下，其对金黄色葡萄球菌和大肠杆菌的抗菌率分别超过96%和99%。细胞毒性分析表明，该水凝胶对NIH3T3细胞表现出优良的生物相容性。 |
| Abstract: |
| This paper designed and synthesized copper/nickel-coordinated imidazolium ionic liquids (denoted as IL/Cu and IL/Ni， respectively) and further investigated their properties. Multifunctional cellulose hydrogels， designated as CH-CTA-PIL/Cu and CH-CTA-PIL/Ni， were successfully fabricated via a grafting polymerization strategy. The results showed that resulting hydrogels exhibited exceptional photothermal responsiveness under 808 nm near-infrared (NIR) irradiation， achieving a temperature elevation of 27 ℃， along with favorable thermal stability. Antibacterial evaluation demonstrated their effective inhibition of S.aureus and E.coli growth both with and without light exposure， antibacterial rates of these hydrogels exceeded 96% and 99% against S.aureus and E.coli， respectively， under NIR irradiation. Cytotoxicity analysis indicated excellent biocompatibility of these hydrogels with NIH3T3 cells. |
