Developing large-scale hydrogels with high tensile strength and robust mechanical properties is an intricate challenge of great industrial significance. In this study, we demonstrate an efficient method for producing nanocomposite hydrogels with extraordinary mechanical properties. Our approach involves a two-step process: an initial stage of pre-cross-linking boron nitride (BN)-enriched pre-gel sodium alginate, followed by cross-linking with metal ions. In stark contrast to conventional sodium alginate hydrogels (SA), our newly formulated ‘BS hydrogel’ exhibited an impressive tensile strength exceeding 41 MPa and improved thermal resistance. Moreover, the reconstituted BS hydrogel exhibited tensile strengths ranging from 47 to 96 MPa and elastic moduli ranging from 199 to 1184 MPa, depending on the cross-linking metal ions. These findings indicate the multifaceted potential of the BS hydrogel, which is poised to revolutionize many applications and represents a significant step forward in hydrogel technology for industrial applications.

氮化硼-海藻酸盐配位相互作用使水凝胶具有增强的机械强度和耐热性

开发具有高拉伸强度和强大机械性能的大规模水凝胶是一项具有重大工业意义的复杂挑战。在这项研究中，我们展示了一种生产具有非凡机械性能的纳米复合水凝胶的有效方法。我们的方法涉及两步过程：预交联富含氮化硼（BN）的预凝胶海藻酸钠的初始阶段，然后与金属离子交联。与传统的海藻酸钠水凝胶 (SA) 形成鲜明对比，我们新配制的“BS 水凝胶”表现出超过 41 MPa 的令人印象深刻的拉伸强度和改进的耐热性。此外，重构的 BS 水凝胶表现出 47 至 96 MPa 的拉伸强度和 199 至 1184 MPa 的弹性模量，具体取决于交联金属离子。这些发现表明了 BS 水凝胶的多方面潜力，它有望彻底改变许多应用，代表着水凝胶技术在工业应用方面向前迈出了重要一步。
