防水透气膜（WBM）因其在户外防护服、医疗卫生和电子设备方面的广泛应用而在全球范围内受到广泛需求。然而，这种材料的环保性和高功能性的设计一直被认为是一个长期存在的挑战。在此，我们报道了通过乙醇基静电纺丝和水基浸渍技术，绿色溶剂加工的具有双疏性和键合结构的聚酰胺纤维膜，赋予纤维膜优异的防水、防油、防尘和良好的透气性能。所开发的绿色智能纤维膜具有综合性能，水侵入压力为101.2 kPa，油侵入压力为32.4 kPa，除尘效率高达99.9%以上，水蒸气透过率为11.2 kg m–2d–1，透气度为2.6 mm s–1，拉伸强度为15.6 MPa，韧性高达22.8 MJ m–3， 使膜能够有效地保护人类和电子设备。这项工作可能有助于设计用于防护纺织品的下一代绿色智能纤维 WBM。
Waterproof and breathable membranes (WBMs) are highly demanded worldwide due to their promising applications in outdoor protective clothing, medical hygiene, and electronic devices. However, the design of such materials integrated with environmental friendliness and high functionality has been considered a long-standing challenge. Herein, we report the green-solvent-processed polyamide fibrous membranes with amphiphobicity and bonding structure via ethanol-based electrospinning and water-based impregnating techniques, endowing the fibrous membranes with outstanding water/oil/dust-resistant and good breathable properties. The developed green smart fibrous membranes exhibit integrated properties with robust water and oil intrusion pressures of 101.2 and 32.4 kPa, respectively, excellent dust removal efficiency of above 99.9%, good water vapor transmission rate of 11.2 kg m–2d–1, air permeability of 2.6 mm s–1, tensile strength of 15.6 MPa, and strong toughness of 22.8 MJ m–3, enabling the membranes to protect human beings and electronic devices effectively. This work may shed light on designing the next generation green smart fibrous WBMs for protective textiles.
