Molecular desalination is broadly used in chemical, food, and textile industries, which needs efficient and anti-fouling separation technologies to reach this goal. Interfacial polymerization is one of the most promising routes to construct ultrahigh selective nanofiltration membranes. However, the irreversible hydrolysis of residual acyl chlorides makes Donnan charges of nascent films distribute unevenly which hinders fine molecular desalination and anti-fouling. Here, we propose a pioneering solvation-amination-synergy strategy to synchronously inhibit the hydrolysis of residual acyl chlorides and promote their amination. The electroneutral nanofiltration membrane with high water permeance (13.2 L m⁻² h⁻¹ bar⁻¹) is quantitatively fabricated that has superb anti-fouling abilities and minimizes Donnan impacts on competitive ion penetrations, so it transmits Na₂SO₄ and NaCl while fully obstructs cationic or anionic dyes (< 500 Da). The ultrahigh molecule to ion selectivities outperform state-of-art nanofiltration membranes, which may provide a paradigm shift for scalable membrane fabrication for various industrial product desalination.

溶剂化-胺化-协同作用，中和用于超高选择性纳滤的界面聚合膜

分子脱盐广泛应用于化工、食品、纺织等行业，需要高效、防污的分离技术来实现这一目标。界面聚合是构建超高选择性纳滤膜最有希望的途径之一。然而，残留酰氯的不可逆水解使新生膜的Donnan电荷分布不均匀，阻碍了精细分子的脱盐和防污。在这里，我们提出了一种开创性的溶剂化-胺化-协同策略，以同步抑制残留酰氯的水解并促进其胺化。具有高透水性的电中性纳滤膜（13.2 L m ^-2  h ^-1  bar ^-1) 是定量制造的，具有出色的防污能力，并将 Donnan 对竞争性离子渗透的影响降至最低，因此它可以传输 Na ₂ SO ₄和 NaCl，同时完全阻挡阳离子或阴离子染料 (< 500 Da)。超高分子对离子的选择性优于最先进的纳滤膜，这可能为各种工业产品脱盐的可扩展膜制造提供范式转变。
