我们已经开发出含有铁蛋白纳米颗粒的坚韧纳米纤维水凝胶，其核壳结构适合于降低应力浓度。纳米复合水凝胶在外力作用下的溶胀性能增强，吸水速度快。在溶液中测量的纳米复合水凝胶的弹性模量、抗拉强度和断裂伸长率与裸聚合物水凝胶相比显著提高。在拉伸试验中，纳米填料与聚合物基体之间的强结合对增强复合水凝胶纤维的韧性起着重要作用。(C) 2008年美国物理研究所。(DOI: 10.1063/1.3005596)
We have developed tough nanofiber hydrogels incorporating ferritin nanoparticles with a core-shell structure that is suitable for stress concentration reduction. The swelling properties of the nanocomposite hydrogel under external forces were enhanced, leading to fast water absorption. The elastic modulus, tensile strength, and elongation at break of the nanocomposite hydrogel measured in solutions were dramatically enhanced as compared to those of the bare polymer hydrogel. During the tensile tests, the strong bonding between the nanofiller and polymer matrix played an important role in enhancing the toughness of the composite hydrogel fibers.
