Research progress of polyvinyl alcohol-based physical crosslinked gels featuring high mechanical properties
随着人工智能、人机交互等前沿科学的兴起和快速发展,柔性凝胶材料得到广泛研究与报道.聚乙烯醇作为一种具有良好生物相容性和多功能组分适配性的低成本高分子,是凝胶骨架的理想构筑基元.本文通过调研近年来聚乙烯醇基凝胶材料的研究成果,综述了其物理交联网络的设计方法,包括冻融法、盐析法、退火法、溶剂交换法等,重点阐述了增强材料力学性能的策略.在此基础上,分析了目前制备高力学性能聚乙烯醇基凝胶面临的挑战,并对其发展方向与应用前景进行了展望.
With the emergence and rapid advancement of cutting-edge sciences like artificial intelligence and brain-computer interface,significant progress has been achieved in the development of flexible gel materials.Due to the good biocompatibility,adaptability to multifunctional components,and cost-effectiveness,polyvinyl alcohol(PVA)is widely used as an ideal skeleton for the construction of gel materials.According to the reports on PVA-based gels in the past years,in this paper,we provide a comprehensive overview of design methods,especially the mechanical reinforcement strategies,to construct physical crosslinked networks of PVA,including freeze-thawing,salt-outing,annealing,and solvent exchange.Furthermore,we summarize the current challenges in high-performance PVA-based gel materials,and propose insights into future developments and potential applications.
