preparation example Construction

[0068] In one embodiment, the method for preparing MOF-modified fibers includes the steps of: providing a suitable material; and exposing the material to MOF under conditions that allow the formation of the MOF-modified material. For example, Figure 1 shows the method of MOF199 incorporation into anionically modified cellulose fibers.

[0069] In another embodiment, a method for preparing a MOF-modified material includes the steps of: providing a suitable material; and exposing the material to a mixture of MOF precursors under conditions that allow the formation of a MOF-modified material. In this embodiment, the MOF is synthesized in situ in the presence of the material such that the MOF is covalently bound to the fiber.

[0070] In the method of the present invention, appropriate reaction conditions should be determined (for example, reagent amount, solvent, reaction temperature, and reaction pressure are all within the consideration of those skilled in the art).

Embodiment 1

[0089] General experiment: Prepare chemically modified cellulose (anionic cellulose) before the experiment. Copper(II) acetate, 1,3,5-benzenetricarboxylic acid, methanol (MeOH), dimethylformamide (DMF), and ethanol (EtOH) were obtained from Sigma-Aldrich (St. Louis, MO). All chemicals and reagents used were of analytical grade. Scanning electron microscope (SEM) micrographs were recorded using a scanning electron microscope (SEM, LEO1550FE-SEM) at 20 kV, and the surface was coated with carbon before analysis. Powder X-ray diffraction patterns were collected using an X-ray diffractometer in Rigaku SmartLab. Thermogravimetric analysis (TGA) using a thermogravimetric analyzer at N 2 And the analysis is carried out under the conditions of 30°C to 600°C. Fourier transform infrared spectroscopy (FT-IR) analysis was performed using a Nicolet Magna 760 FTIR spectrometer (Thermo Fisher Scientific Inc., Waltham, MA) in single attenuated total reflectance (ATR) mode. X-ray photoelect...

Abstract

The invention relates to a MOF (metal organic framework)-modified materials and methods of making and methods of using same. The MOFs are covalently bound to the materials. Examples of suitable materials include fibers and thin films. The MOF-modified materials can be made by forming MOFs in situ such that they are covalently bound to the materials. The MOF-modified materials can be used in methods where gases and / or toxic chemicals are absorbed.
