近些年,福州大学先进纤维团队一直致力于超浸润材料粘附可控方面研究(Adv. Mater. 2009, 21, 3799; Adv. Mater. 2013, 25, 1682; Adv. Funct. Mater. 2018, 28, 1707415; Adv. Mater. 2019, 31, 1806314; Adv. Funct. Mater. 2022, 32, 2200359; Adv. Mater. 2022, 34, 2204581; Adv. Funct. Mater. 2023, 33, 2302038; Chem. Soc. Rev. 2023, 52, 473; Adv. Funct. Mater. 2024, 34, 2402853 etc),并探讨了超浸润性膜材料在多相分离纯化等环境保护方面的工作(Energy & Environ. Sci. 2018, 11, 772; Chem. Eng, J. 2018, 333, 621; ACS Nano 2022, 16, 18018; Environ. Sci. & Technol. 2022, 56, 17288; Green Energy & Environ. 2023, 8, 673; Adv. Fiber Mater. 2023, 5, 1505; J. Membr Sci. 2023, 690, 122217; Matter 2023, 6, 3509; Adv.

最近,福州大学赖跃坤教授团队前期工作基础上,创新地提出了射流劈裂静电纺丝新方法,构筑了超轻薄高性能纳米/亚微米双尺度纤维膜滤料(Nature Communications, 2024, 15, 1586)。近日,团队又进一步发展了耦合射流劈裂静电纺丝与滤料拓扑结构设计策略,可控地制备出一种双尺度纤维/串珠纤维三明治结构复合膜,同时赋予空气滤料高防护性和高舒适性,为聚合物纤维材料进一步突破直径极限、实现超细纳米化成型提供了新思路,同时也为舒适性防护空气滤料的设计和制备提供了新方法。相关研究以“Sandwich-structured bimodal fiber/bead-on-string fiber composite membrane for comfortable PM0.3 filter”为题发表在Chemical Engineer Journal, 2024, 495, 15324。
