Product Overview

The concept of Covalent Organic Frameworks (COFs) materials was first proposed in 2005 by Yaghi et al., aiming to develop a new class of porous materials with highly ordered structures and specific functions. COF is a kind of crystalline organic porous polymer material with periodic structure formed by strong covalent bond of light elements (such as C, H, O, N, etc.). COF is derived from the polymerization of small organic molecules. In order to meet the requirements of high crystallinity of COF materials, COF needs to continuously complete the recombination of covalent bonds in the polymerization process to form a long-range ordered crystal structure. Depending on the type of reaction, the main reactions to produce COF are: boric acid polycondensation (boron-oxygen bond), C-C coupling reaction (carbon-carbon bond), Schiff base reaction (imine bond), cyano-autopolymerization (triazine bond) and aryl ether polymerization (carbon-oxygen bond) reaction. Among them, CFS containing reversible boro-oxygen bonds, imine bonds and triazine bonds are the most common and widely used. The common methods of COF synthesis include solvothermal method, microwave assisted solvothermal method, mechanical force method, ionic thermal method and room temperature solution synthesis method.


Technical Parameter

Specific surface area: ~1634 m2/g

Pore size:~2.3 nm

 

Product Features

 

Low density: composed of C, H, O, N, B and other lightweight elements, low density.

High specific surface area: provides a large number of active sites and adsorption sites.

Chemical modifiability: Functional modifications can be made through the design and selection of organic monomers.

Good thermal stability and chemical stability: can maintain structural stability in a certain temperature and chemical environment.

Excellent pore properties: conducive to gas adsorption, storage and separation.

 

 

Application Fields

 

Gas storage and separation: COFs is known as a new type of porous crystal material for gas storage due to its high inherent specific surface area, extremely low density, high stability and adjustable pore size, such as storing hydrogen, carbon dioxide and other gases, and achieving efficient gas separation.

Catalysis: As a catalyst or catalyst carrier, participating in various chemical reactions. For example, improving the efficiency and selectivity of the reaction in organic synthesis. Its insolubility and high stability make it easy to separate from the reaction mixture, and the catalyst has good reusability.

Energy storage: Used for lithium-ion batteries, supercapacitors and other energy storage devices. Improve battery charging and discharging performance and cycle stability.

Sensing: Detect various substances in the environment, such as gas molecules, heavy metal ions, etc. It can be used for pollutant detection in environmental monitoring.

Liquid phase adsorption separation: A large number of open channels, large specific surface area, easy access to binding sites and high chemical stability make COF an excellent material for liquid phase adsorption.

Worth the expensive price tag!
Color: Brown, Style: Wallet With Airtag Pocket
Was skeptical at first thinking it will be like other same products and will under deliver, costly but worth the spend. Leather looks premium, no loose buttons and can easily hold 15 cards along with some money clips. Totally sold on this product. If you want quality product and don’t care about the price just get this one. Magnet is also strong inspite of filling it to the brim

Easy on older hands and not too tight!
Color: Navy Blue, Style: Standard Wallet
MUCH better than my first minimalist wallet purchase. Though this one is a little bigger than the last (but still far smaller than a bill fold), it is FAR easier to maneuver. I really like the separate pockets for a few extra cards I use much more often. It took a couple weeks to break it in so cards now move easier than day one and now it's perfect. The money "clip" is also a better feature than the elastic band money clips that some other wallets have, which stretch and get too loose over time. This wallet is far easier for older hands. My last wallet forced me to line up every card perfectly in order to push them back into the spring compartment and bound them so tightly that I could barely get them apart enough to pull the card I needed. This one is far less finicky and less demanding of perfection, making it far easier to push a pack of cards back inside. The thumb pull is really easy to work and the wallet holds everything very securely, yet easy to get around in. It's comfortable, very durable, nice looking and the craftsmanship is superior.

Great wallet with tons of pockets!
Color: Carbon Fiber Black, Style: Wallet With Airtag Pocket
After losing my wallet and finding it right in n front of my face after hours of looking for it I got this one and it’s very stylish with more pockets than i ever needed. The air tag makes it look even better but the fact that i can find it when I’ve misplaced it is very reassuring!

Great wallet.
The card spots work great and the money clip part actually works. I was skeptical at first but the wallet is quite helpful in organizing my cards and money. The material is quite nice and it does seem quite durable.

Wonderful
Fantastic buy! This contains everything I need (minus a phone), and because it zips up, I know everything is secure. I recommend this product.
