Gongye shui chuli, 2016 为弥补强疏水性聚偏氟乙烯（PVDF）膜在实际应用中的缺陷，从膜本体及膜表面2个角度入手，阐述了国内外对PVDF膜亲水化改性的主要方法。膜本体改性主要是将膜材料与亲水性聚合物或无机纳米材料共混，从而改善PVDF膜的亲水性能；而膜表面改性则主要是通过表面涂覆改性与表面接枝改性来实现。PVDF膜亲水性的增强，能有效改善膜的抗污染能力，从而大大提高膜的过水通量，并延长其使用寿命。

New Phytologist, Volume 251, Issue 1, Page 207-227, July 2026.Network of VAMP714‐dependent interactions during salt stress. Summary Plant responses to salt stress include an altered root architecture mediated by ion imbalances, reactive oxygen species (ROS) accumulation, and altered hormonal responses. Auxin is implicated in these processes.
