摘要
水凝胶的物理性质与生物组织相似,具有优异的生物相容性,在医药领域研究日渐深入,同时也对水凝胶的性能提出了更高的要求。要实现水凝胶在有水环境下粘合,具有很大的挑战,但同时也具有巨大的前景。自然界常常给人类的生产生活和科学研究带来许多启发。自然界中,有许多生物为了抵御复杂环境带来的影响,通常能黏附于介质表面保证自身安全并得以生存,这得益于实现粘附的生物表面分泌特殊的分泌化学成分和/或具有特殊的微结构。为了更好地理解水下黏附材料的作用机理,本文简要概述了近年来受自然界启发的水下粘合剂的设计策略。本文讨论了包括贻贝、藤壶、沙堡蠕虫、蛞蝓、树蛙、章鱼等动物以及常春藤、爬山虎等植物的黏附机制以及受其启发设计的仿生策略。最后,展望了仿生水下黏附水凝胶设计的不足和发展前景。
Abstract
The physical properties of hydrogels are similar to those of biological tissues, with excellent biocompatibility. And the research in the field of medicine is becoming more and more in-depth. At the same time, higher requirements are also put forward for the performance of hydrogels. Achieving hydrogel bonding in a watery environment is challenging, but at the same time has great promise. The natural world often brings many inspirations to human production and scientific research. In nature, there are many organisms that, to resist the effects of the complex environment, usually adhere to the surface of the medium to ensure their safety and survival, thanks to the special secretion chemical composition and/or microstructure of the biological surface that achieves adhesion. To better understand the mechanism of action of underwater adhesive materials, this paper briefly summarizes the design strategies of underwater adhesives inspired by nature in recent years. This article discusses the adhesion mechanisms of animals, including mussels, barnacles, sandcastle worms, slugs, tree frogs, octopuses, and plants such as ivy and reptile tigers, as well as biomimetic strategies inspired by them. Finally, the shortcomings and future development trends of biomimetic underwater adhesion are also prospected.
