针对复合纳滤膜选择性和渗透性难以兼顾的问题，提出氧化介导液相沉积策略可控构建超薄均孔金属多酚网络分离层，实现对其孔径和厚度的纳米级精确调控，并通过引入中空MOFs进一步提升其渗透性能。

2. 多孔聚合物纳米片基复合膜

针对二维膜材料层间水通道长而曲折的问题，提出溶剂诱导二维组装策略合成多孔聚合物纳米片，构建丰富的短直水通道，并通过化学键合作用实现层间距的精密调控，发展兼具高渗透选择性和高稳定性的多孔纳米片基复合分离膜。

3. 功能性聚合物纳米复合隔膜材料

针对锂金属电池中电极界面副反应等问题，开发功能性聚合物纳米复合隔膜新材料，发展离子选择性电荷调控和纤维孔隙结构调控策略，建立此类复合隔膜的高离子传导和抑制界面副反应双效作用机制，拓展其在高性能柔性储能器件领域的应用和发展。
