Abstract

Polymer hydrogels have the characteristics of porous structure and high histocompatibility, and exhibit remarkable stability in various industrial fields. In this study, the highly elastic antibacterial rosin-modified cellulose nanocrystal (CNC) hydrogel was successfully prepared. The mechanical properties, swelling properties and antibacterial properties were investigated through a series of characterizations. The hydrogel prepared in this study exhibited a maximum elongation of 1379%. Scanning electron microscopy results revealed a tightly knit network structure in the hydrogel synthesized through UV-initiated polymerization. In terms of antibacterial properties, the Rosin@CNC hydrogel demonstrated significant inhibitory effects on both Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli. With a maximum swelling ratio of 603.42%, it showed excellent swelling capacity, enabling it to absorb and retain large amounts of water, accommodating various materials including small molecules, polymers, and particles. These characteristics positioned it as a promising antibacterial material with broad application prospects in the fields of biomedicine, plant protection and water treatment.

基于松香改性纤维素纳米晶的高弹性抗菌水凝胶的快速合成

聚合物水凝胶具有多孔结构和高组织相容性的特点，在各种工业领域表现出显著的稳定性。本研究成功制备了高弹性抗菌松香改性纤维素纳米晶（CNC）水凝胶。通过一系列表征研究了其力学性能、溶胀性能和抗菌性能。本研究制备的水凝胶的最大伸长率为1379%。扫描电镜结果显示，通过紫外光引发聚合合成的水凝胶具有紧密的网状结构。抗菌性能方面，Rosin@CNC水凝胶对革兰氏阳性金黄色葡萄球菌和革兰氏阴性大肠杆菌均有明显的抑制作用。其最大溶胀率为603.42%，具有良好的溶胀能力，可以吸附和保留大量的水，可以容纳小分子、聚合物、颗粒等多种材料。这些特性使其在生物医药、植物保护、水处理等领域具有广阔的应用前景，是一种很有前途的抗菌材料。图形抽象
