“…The presences of P, Ag, and Cu elements are all detected, indicating the existence of PA-M complex on the surface of TFC_PA-M membranes. In addition, the high resolution XPS spectra of different elements are further deconvoluted to obtain the chemical states of the above elements. , For the TFC_PA-Ag membrane, the peaks of O–Ag bond (O 1s, 530.1 eV), P–O–Ag bond (P 2p, 135.0 eV), and Ag–O bond (Ag 3d 3/2 , 375.6 eV and 3d 5/2 , 369.4 eV) verify the strong chelation interaction between Ag + and PA, confirming again the formation of PA-Ag complexes by the assembly of Ag + and PA. Moreover, the existence of N–Ag (N 1s, 401.2 eV), Ag–OC (Ag 3d 3/2 , 375.6 eV and 3d 5/2 , 369.4 eV), and Ag–N (Ag 3d 3/2 , 374.8 eV and 3d 5/2 , 368.5 eV) bonds suggests the interaction between Ag and amide groups, carboxyl groups, and the residual terminal amine (from the pristine polyamide selective layer), indicating the good adhesion of PA-Ag complexes on the TFC membrane surface as proposed above.…”

Polyamide TFC membranes are widely applied in membrane-based water treatment but generally suffer various fouling problems. In this work, the layer-by-layer assembly of phytic acid (PA) and metal ions (M) is constructed on the surface TFC membrane for the first time, to improve the bio/organic fouling resistances and separation performance of TFC membranes simultaneously. The PA molecule with six phosphonic acid groups of strong chelation ability acts as the organic ligand, and the metal ion acts as the inorganic cross-linker, inducing the assembly of hydrophilic and antibacterial PA-M (Ag or Cu) complexes on the TFC membrane surface. Various characterizations including FTIR, XPS, SEM, AFM, and EDX are employed to confirm the successful and uniform modification of PA-M. FO performance of the PA-M modified TFC membranes, i.e., TFC_PA-Ag and TFC_PA-Cu, is optimized by varying PA concentration and assembly cycles, where the water flux can be improved by 57% and 68%, respectively, without compromising the membrane selectivity. Additionally, the PA-M modification improves the biofouling and organic fouling resistances of the TFC membrane remarkably, owing to the enhanced antibacterial ability and hydrophilicity. The modified TFC membranes are also proven to show the excellent stability by the quantitative release test.

“…With prolonging the soaking time, the surface is gradually coated with PA‐M films (Figures S2 and S3, Supporting Information). However, many cracks appear on the surface of the films due to the residual stress, [ 21 ] when the growth time is extended to 30 min. Considering that the grown film should have a certain thickness to accumulate the fluctuation during continuous charging and discharging, the optimal growth time is 15 min to maintain the integrated interface layer.…”

Alternatively, zinc with large theoretical capacity (gravimetric capacity −820 mAh g −1 and volumetric capacity −5855 mAh cm −3 ), appropriate low potential (−0.762 V versus standard hydrogen electrode) and good stability than alkaline metals, is particularly attractive in the scientific and technological areas. [2] For example, the alkaline zincmanganese dioxide batteries have been commercially used as the specific primary battery. [3] Notably, the mercury was originally added to provide the corrosion protection. Currently, the formation of zinc Scheme 1. The formation process of PA-M films and the proposed interface reactions. a) Scheme illustrations for interface reactions with and without PA-M films on the Zn surface. b) The proposed dynamic coordination process of Zn 2+ ions via coordinated hopping mechanism.

“…This is due to the neutralization reaction between ATMP and MH. The peaks noticed at 1230 and 1640 cm −1 corresponded to the typical P═O stretching vibration and the O─H bending vibration from the P─OH group . Further, it is a broad hydroxylation association peak in the range of 2595 to 3011 cm −1 .…”

In this work, a novel multifunctional organic-inorganic hybrid flame agent (AM-MEL) was prepared from magnesium hydroxide nanosheets decorated by nitrilotrimethylene triphosphonic acid and melamine. Then, an intrinsic flame-retardant epoxy resin (EP) was prepared by covalently incorporating AM-MEL nanoparticles. Meanwhile, ammonium polyphosphate (APP) was added into EP to form an intumescent flame retardant system with AM-MEL. The chemical structure of AM-MEL was characterized by Fourier transform infrared spectra, X-ray photoelectron spectroscopy, and scanning electron microscopy. With the incorporation of 5 wt% AM-MEL and 15 wt% APP, EP/AM-MEL/APP could reach a limiting oxygen index value of 32.0% and achieve UL-94 V-0 rating, along with 88.0%, 70.0%, 81.5%, and 87.3% decrease in the peak heat release rate, total heat release, total smoke production, and the peak CO production rate, respectively, with respect to that of pure EP. The mechanisms of its flame retardant and smoke suppression were investigated.
