10月26日上午，韩国汉阳大学教授Young Moo Lee应邀访问材料化学工程国家重点实验室，并在创新楼学术报告厅(C502)做了题为“Cactus-inspired Self-humidifying Membranes”的学术报告。报告由重点实验室常务副主任金万勤教授主持，部分老师和研究生参加了报告会。

Lee教授首先讲述了聚合物膜中水含量的调节对于众多应用（如反向电渗析和质子交换燃料电池膜）都很重要，针对此背景，受沙漠中仙人掌全身有层防水的蜡质膜覆盖的启发，Lee教授及其团队设计了一种不需要调节外界条件，而是利用一层具有“纳米尺度裂缝”的疏水性涂层来自我控制碳氢聚合物膜的水含量。这种“仙人掌式”膜表面涂层中的“纳米裂缝”就相当于仙人掌的气孔，可调节电化学反应生成的水。这些裂缝会在湿润条件下扩大，而在干燥条件下关闭，在膜除湿过程中就可以防止水分的脱出而保证离子导电性。实验结果也证明了这个结构在中温操作条件下提高了碳氢燃料电池膜的电化学性能，也提高了所涂覆的反向电渗析的离子电导率。

报告内容引起了在场师生的浓厚兴趣，参加报告会的老师和同学们也都相继和Lee教授进行了互动学术交流,。
