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: ~25.7 m2/g

Pore size:~17.88 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.

This jacket is a head-turner.
Color: Red, Size: X-Large, Color: Red, Size: X-Large
This is a fantastic jacket for the price. I was very impressed by its appearance. I wore the jacket in Las Vegas and got so many compliments from both men and women. Pair this with a black turtleneck and you will be a superstar.

it caused a fight
Color: Gold, Size: X-Large
I completely mis-read the room.... I got this jacket as a White Elephant gag gift for our Christmas party. I thought it would be funny to see some 50-60 year old conservative dude open this up. There is nothing subtle about this jacket. It's bright. It's flashy. It's bold. The guys fought over it. It was the most stolen gift of the night. When the first guy opened it, the whole party stopped for a minute while he proudly tried it on and everyone took pictures. And each time it was stolen, the same thing happened. The loser moped. The winner boasted. It was not at all the reaction I expected from this group - it was awesome! And to top it off, a couple months later another guy in the group "borrowed" the jacket and wore it for his wedding. His wife - also part of our group - absolutely loved it! He has no plans to return the jacket to any of the previous owners. Don't be surprised if you see a sparkling flash of light in the stands at a Vanderbilt basketball game! Their colors are black/gold, so he's going to make full use of the blazer! Aside from making a great story for all of us, this jacket is very well made. The sequins are firmly attached. The sleeves are the right length, etc. It's comfortable to wear and the sizing feels accurate. I was expecting a "costume" piece, but actually got a quality blazer.

Quite good for costume quality
Color: Gold, Size: Medium
For eighty bucks this definitely isn't bad. It arrived slightly out of shape but after a few days on a good hanger, it all fell into place. I had no issues with fit--the medium wears as expected (6', 38" chest). It's a fun jacket, it's not far off from the product photos, and it certainly makes an impression. While it doesn't feel 'premium' per se, it doesn't feel cheap either. The liner is solid enough that the sequins don't feel too scratchy or restrictive. Definitely a niche item--certainly more of a costume piece than something you'd wear to make a bold impression at a formal event, and while not inexpensive, it delivers for the price and I don't think you could do much better for $80.
