有机染料和金属造成的全球水污染可以通过吸附来解决。特别是，水凝胶吸附剂由于其三维多孔结构而显示出独特的优势。在这里，制备了一种基于硼酸酯和酰胺键的新型自修复水凝胶。首先通过酰胺化合成了前体聚合物2-氨基苯硼酸改性聚丙烯酸（PAA-2APBA），然后将聚乙烯醇和合成锂皂石与PAA-2APBA混合形成纳米复合水凝胶。结果表明，这种水凝胶具有良好的自愈性和可注射性，以及良好的生物相容性。将合成锂皂石纳米颗粒引入水凝胶中，提高了水凝胶的稳定性、机械强度以及金属离子和有机染料的吸附效率。铜离子、镉离子、铅离子和铁离子的最大吸附量分别为259.1 mg/g、243.4 mg/g、217.4 mg/g和166.2 mg/g。对于有机染料，28 小时内去除了 71% 的亚甲基蓝和 81% 的孔雀石绿。
Global water pollution by organic dyes and metals may be solved by adsorption. In particular, hydrogel adsorbents display unique advantages due to their three-dimensional porous structure. Here, a new type of self-healing hydrogels based on boronate and amide bonds were prepared. The precursor polymer, 2-aminophenylboronic acid-modified polyacrylic acid (PAA-2APBA), was firstly synthesized by amidation, then, the poly(vinyl alcohol) and laponite were mixed with PAA-2APBA to form a nanocomposite hydrogel. Results show that this hydrogel has good self-healing and injectable properties, as well as good biocompatibility. The introduction of laponite nanoparticles into the hydrogel improved the stability, mechanical strength, and the adsorption efficiency of metal ions and organic dyes. The maximum adsorption of copper ion, cadmium ion, lead ion, and iron ion was 259.1 mg/g, 243.4 mg/g, 217.4 mg/g, and 166.2 mg/g, respectively. For organic dyes, 71% of methylene blue and 81% of malachite green were removed in 28 h.
