The high mechanical strength and self-healing properties of hydrogels are the focus of tissue engineering and biomedical research. Furthermore, the incompatibility between hydrogel toughness and self-healing has not been resolved. It is noteworthy that the double network (DN) hydrogels show great promise as a viable method for producing self-healing hydrogels with the above properties. The Xylan/PVA/Borax DN hydrogel was prepared by the one-pot method, shows various excellent performances, including strong strength (ca. 81 kPa), high toughness (ca.1652.42 kJ/m), good self-recovery (ca. 79% recovery), and excellent self-healing properties (self-healing efficiency reached to 85.8% for 30 s). This study proposes a strategy to design high strength, high toughness, large extensibility, and self-healing properties hydrogels based on xylan.
水凝胶的高强度和自修复性能是组织工程和生物医学研究的重点。此外，水凝胶韧性和自修复之间的不兼容尚未得到解决。值得注意的是，双网络（DN）水凝胶作为一种可行的方法，有望制备具有上述性能的自修复水凝胶。通过一锅法制备了木聚糖/聚乙烯醇/硼砂双网络水凝胶，表现出各种优异的性能，包括高强度（约 81kPa）、高韧性（约 1652.42kJ/m）、良好的自恢复性（约 79%的恢复）和优异的自修复性能（自修复效率达到 30s 时的 85.8%）。本研究提出了一种基于木聚糖设计高强度、高韧性、大拉伸性和自修复性能水凝胶的策略。
