The invention discloses protein adhesion hydrogel for an underwater soft robot and preparation and application of the protein adhesion hydrogel, a recombinant arthropoelastin solution is pre-crosslinked through dityrosine, ferroferric oxide nanoparticles are added, then a mixed solution and a silicotungstic acid solution are subjected to a crosslinking reaction, and the underwater adhesion hydrogel is obtained. According to the invention, while the positively charged amino acid of the recombinant arthropoelastin is adhered underwater, the polyanion characteristic of silicotungstic acid enables the recombinant arthropoelastin to generate electrostatic interaction with various positively charged substances, so that the protein and silicotungstic acid can be cross-linked to form hydrogel, and the adhesion performance and mechanical performance of the material are enhanced. Due to the existence of the ferroferric oxide nanoparticles in the hydrogel, the hydrogel can respond to magnetic force and infrared light to carry out controllable movement and underwater adhesion, so that the application of grabbing and delivering objects in an underwater environment, repairing artificial blood vessels and the like is realized, and the hydrogel has wide application value and prospect in the fields of biomedicine, marine exploration and the like.

    一种用于水下软体机器人的蛋白黏附水凝胶及其制备和应用,通过将重组节肢弹性蛋白溶液经过二酪氨酸预交联后加入四氧化三铁纳米颗粒,再将混合溶液与硅钨酸溶液进行交联反应,得到水下黏附水凝胶。本发明利用重组节肢弹性蛋白的带正电氨基酸在水下进行黏附的同时,通过硅钨酸的聚阴离子特性使其能够与各种带正电荷的物质发生静电相互作用,使得蛋白与硅钨酸能够交联形成水凝胶,并加强了材料的黏附性能以及机械性能。并由于水凝胶内四氧化三铁纳米颗粒的存在,使得其能够响应磁力及红外光进行可控的移动与水下黏附,实现水下环境的物体抓取与递送、人造血管的修复等应用,在生物医学、海洋勘探等领域具有广阔的应用价值与前景。
