However, the separation layer of traditional thin-film composite (TFC) NF membranes is relatively thick and loose, resulting in unsatisfactory water permeance and separation performance. In this study, a novel high-valent metal-induced microporous polymer, HMMP-2, was synthesized. Then, the polydopamine (PDA)/HMMP-2 interlayer was constructed by depositing HMMP-2 on the polysulfone membrane via PDA-assisted deposition. The interlayer had a hydrophilic and rough surface, enabling the retention of more piperazine monomers to regulate the interfacial polymerization (IP) process. Subsequently, an ultrathin (thickness reduced from 100.41 ± 5.22 nm to 30.02 ± 4.48 nm) and dense polyamide separation layer was fabricated via IP reaction on the interlayer. Additionally, the hydrophilicity of the interlayer combined with the suitable pore size of HMMP-2 synergistically enhanced transmembrane water transport, significantly improving the water permeance of the NF membrane. The optimized membrane, NF-PH(5), demonstrated superior water permeance of 20.93 ± 1.13 L m⁻² h⁻¹·bar⁻¹, representing a 193.53 ± 15.18 % enhancement compared with the control membrane (NF0). The NaCl/Na₂SO₄ separation factor of NF-PH(5) reached 62.88 ± 5.40, showing an increase of 91.42 ± 4.92 % over NF0. Moreover, NF-PH(5) exhibited superior perm-selectivity in the mixed-salt solution compared with NF0. The fabricated NF membrane with a PDA/HMMP-2 interlayer also demonstrated excellent operational stability.

First, a PP membrane, prepared via the thermally induced phase separation (TIPS) method, was spray-coated with a solution containing amine-functionalized silica (NH₂-SiO₂) nanoparticles (NP) and an epoxy polymer resin, followed by a curing step. NH₂-SiO₂ NP were immobilized onto the PP substrate via crosslinking between the amine groups and the epoxy groups of the polymer resin and adhesion property of the epoxy resin.

To investigate such direct effects, we adopted iron-tannic acid (Fe-TA) complex as a model interlayer targeting OMPs removal, and prepared identical polyamide nanofilms for both the control and TFNi membranes at a support-free interface to minimize the impact of interlayer on the polyamide formation. The experimental result shows that, although at the expense of sacrificing water permeance, the interlayer can directly serve as a barrier layer to some OMPs, especially those that cannot be easily removed by the polyamide layer alone, due to the inherent hotspot of polyamide material. A theoretical analysis further suggests that, to enhance the OMPs removal by exerting such direct effects, an ideal interlayer should be more intrinsically selective to OMPs and meanwhile impose moderate resistance to water compared with the polyamide layer.
