The layered double hydroxides (LDH) intermediate layer facilitates controlled interfacial polymerization between trimesoyl chloride and piperazine, which results in two membranes with good separation performances towards salts and dyes.

2022年4月25日 · LDH films with different orientations are prepared by controlling the pH value under in-situ growth process. The orientation of LDH film is related to the active dissolution rate of Al in the substrates. Parallel oriented LDH films exhibit excellent shielding and lubrication ability.

2021年2月25日 · A Mg–Zn–Al LDH film can be directly fabricated on a Zn–Al alloyed AZ31 surface through a simple hydrothermal process without introducing extra metal salts. The alloyed layer can act as an internal feedstock of M 2+ and M 3+, a good adhesive base for the LDH to grow, and also an excellent corrosion-protection for the substrate. This ...

Layered double hydroxide (LDH) films have been widely investigated in the last few years because of their promising applications in areas such as catalysis, anti-corrosion coatings for metals, and as components in optical, electrical, and magnetic devices.

2025年2月4日 · Layered double hydroxides (LDHs) have emerged as potential catalysts for sustainable applications due to their structural adaptability and compositional flexibility. This review explores the intrinsic properties of LDHs and their role in …

2022年1月12日 · In this work, hybrid biodegradable films with simultaneous oxygen and water vapor barrier performance were fabricated by a scraping method, which were composed of polylactic acid (PLA) and MgAl-layered double hydroxide (LDH) nanoplatelets modified by 3-aminopropyltriethoxysilane (APTES) (APTES@LDH).

2024年1月30日 · LDH films were successfully fabricated at ambient pressure by hydrothermal treatment on different Mg substrates. The growth rate of LDH layers was significantly accelerated by the alloying elements (Li and Al) in the substrate.

2024年4月19日 · Layered double hydroxide (LDH) films have received extensive attention for their unique physical barrier function and ion exchange properties, which make them promising candidates for corrosion protection of magnesium alloys.

2021年2月19日 · This review presents an overview of the recent developments in the synthesis of layered double hydroxide (LDH) on the anodized films of Mg alloys prepared by either conventional anodizing or plasma electrolytic oxidation (PEO) and the applications of the formed composite ceramics as smart chloride traps in corrosive environments.

2010年8月7日 · Layered double hydroxide (LDH) films have been widely investigated in the last few years because of their promising applications in areas such as catalysis, anti-corrosion coatings for metals, and as components in optical, electrical, and magnetic devices.
