Constructing an interlayer between porous substrate and polyamide (PA) film is effective strategy to overcome the ubiquitous trade-off permeability selectivity, which are both important properties for nanofiltration performance. In this study, a poly(sodium 4-styrenesulfonate) (PSS) assisted interfacial synthesis method was proposed fabricate zeolitic imidazolate framework-8 (ZIF-8) PA micropor...

A novel biobased porous aerogel was synthesized using physical mixing, freeze-drying, and in-situ growth methods. Zeolitic imidazolate frameworks-8 (ZIF-8) were grafted onto the surface of CS/CNF solid composite to form a ZIF-8@CS/CNF aerogel. The structural characteristics adsorption potential investigated. It found that specific area 206 m2/g, water stability CNF enhanced by incorporating CS....

Split-ring resonators are excellent left-handed metamaterials for significant electromagnetic coupling behavior. In this work, a split-ring resonator prepared with Ni-doped zeolitic imidazolate framework-67/epoxy resin (ZIF-67/ER) was embedded in the top layer to optimize microwave absorption efficiency 2–4 GHz frequency band. The ZIF-67/epoxy served as bottom improve 4–8 Honeycomb conductive c...

Bacteria are difficult to be eliminated because of their multi-drug resistance, which brings significant threats public health. Among the antibacterial methods, mechanobactericidal surfaces provide a possible approach solving this problem. In study, generally used mechanical sterilization is developed by fabricating nanostructured coating. The functional coating simply fabricated growing zeolit...

In recent years, alternative methods to conventional synthesis of MOFs (metal-organic frameworks) have emerged due the problematic use solvents for both environment and human health. Here we present ZIFs (zeolitic imidazolate at high pressure by means a hydraulic press provided with heating mechanism. By optimization parameters such as temperature, time addition promotor NH4NO3, considerable in...

Zeolitic imidazolate framework-8 (ZIF-8) is one of the most stable Metal Organic Frameworks currently available, with promising properties in adsorption, separation and catalysis. Herein, we report a method for rapid production ZIF-8 crystals at room-temperature from methanolic solutions containing sodium acetate metal salts. Of different salts tested, copper nitrate presence prompted formation...

Zeolitic imidazolate frameworks (ZIFs) are a new class of nanoporous compounds which consist of tetrahedral clusters of MN4 (M ) Co, Cu, Zn, etc.) linked by simple imidazolate ligands.1,2 As a subfamily of metal-organic frameworks (MOFs), ZIFs exhibit the tunable pore size and chemical functionality of classical MOFs. At the same time, they possess the exceptional chemical stability and rich st...
