| 中文摘要: |
| 聚丙烯（PP）膜因成本低、机械性能优异广泛应用于水处理，但其疏水性引发的膜污染与通量衰减问题严重制约其性能。本文综述了PP膜亲水改性技术，包括本体改性（共聚、共混）与表面改性（涂覆、等离子体处理等），分析了两类方法的机制、优势及局限性。本体改性可提升膜亲水性但可能削弱机械强度，表面改性调控膜的润湿性但存在膜耐久性不足问题。复合改性展现出优化膜综合性能的潜力，但仍需解决工业化适配性差、二次污染及性能不平衡等挑战。未来PP膜的亲水改性需聚焦多技术协同、绿色工艺开发及智能动态调控，以推动PP膜的高效可持续发展。 |
| 英文摘要: |
| Polypropylene (PP) membrane is widely used in water treatment due to its low cost and excellent mechanical properties, but its hydrophobicity seriously restricts its performance due to membrane fouling and flux attenuation. This article reviews the hydrophilic modification technology of PP membrane, including bulk modification (copolymerization, blending) and surface modification (coating, plasma treatment, etc.), and analyzes the mechanisms, advantages, and limitations of the two methods. Body modification can enhance the hydrophilicity of the membrane but may weaken its mechanical strength, while surface modification regulates the wettability of the membrane but there is a problem of insufficient membrane durability. Composite modification shows the potential to optimize the overall performance of membranes, but challenges such as poor industrial adaptability, secondary pollution, and performance imbalance still need to be addressed. The hydrophilic modification of PP membranes in the future needs to focus on multi technology collaboration, green process development, and intelligent dynamic regulation to promote the efficient and sustainable development of PP membranes. |
