摘  要:聚氨酯因其结构的多孔性、灵敏的刺激响应性以及与其他无机或有机材料复合的可加工性能,被广泛用于微胶囊、纳米胶束、纳米水凝胶等可控释放材料的制备研究。分析了聚氨酯用于微胶囊、纳米胶束、纳米水凝胶等可控释放材料研究的结构设计思路,并详述了不同制备方法对聚氨酯基可控释放材料可控释放性能的影响。主要介绍了界面聚合法和乳液聚合法制备单壳层/双壳层微胶囊、化学交联法制备刺激响应型纳米胶束以及物理交联、化学交联和互穿网络技术制备刺激响应型纳米水凝胶。同时总结了聚氨酯基可控释放微纳米材料在纺织化工、医用、农业等领域的应用。分析了聚氨酯基可控释放材料研究中存在的关键问题,并对其未来应用发展方向进行了展望。Polyurethanes are widely used in research on the preparation of controlled release materials such as microcapsules,nanomicelles,and nanohydrogels due to the porous nature of their structure as well as their sensitive stimulus responsiveness and processability to be compounded with other inorganic or organic materials.The structural design idea of polyurethane used in the research of controlled release materials such as microcapsules,nanomicelles and nanohydrogels is analyzed,and the effects of different preparation methods on the controlled release properties of polyurethane-based controlled release materials are described in detail.The preparation of single-shell/double-shell microcapsules by interfacial polymerization and emulsion polymerization,stimulation-responsive nanomicelles by chemical crosslinking and stimulation-responsive nanohydrogels by physical crosslinking,chemical crosslinking and interpenetrating networks are mainly introduced.The applications of polyurethane-based controlled-release micro-nano materials in textile and chemical,medical,and agricultural fields are summarized.Through summarizing and analyzing,key issues in the preparation process of polyurethane-based controlled release materials are identified,and future development directions in applications are anticipated.
