本发明提供一种剪切增稠水凝胶及其制备方法和应用，所述剪切增稠水凝胶由轮烷与金属离子在水溶液中配位交联得到，所述轮烷由带有四个羧基的主体分子穿线到PEG链上得到，所述轮烷的结构如式I所示。本发明通过带有四个羧基的主体分子穿线到PEG链上得到的轮烷上的多级和金属离子形成可逆的配位作用，形成交联点，从而形成水凝胶，由于具有可逆的配位键，对剪切力具有响应，具有剪切增稠性，在剪切增稠材料等领域具有很好的应用前景。

The invention provides a shear thickening hydrogel, a preparation method and an application thereof. The shear thickening hydrogel is acquired in the manner of coordination cross-linking of rotaxane and metallic ions in an aqueous solution; rotaxane is acquired in the manner of threading a main molecule with four carboxy groups onto a PEG chain; the structure of the rotaxane is shown as formula I. According to the invention, the hydrogel is formed in the manner of forming the gluing points under the reversible coordination effect formed by the metallic ions and the multistage on the rotaxane acquired by threading the main molecule with four carboxy groups onto the PEG chain. The hydrogel has reversible coordination bond, response to shearing force and shear thickening property, so that the hydrogel has wide application prospect in the fields, such as shear thickening materials.
