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: ~909 m2/g

Pore size:~8.1 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.

Great toy
Great for an aggressive chewer. I was pleasantly surprised this toy lasted months with my dog chewing at it. Its one of his favorite toys! It cleans easily rinsing in the sink or running it in the washing machine &holds up very well.

Dogs love it
This our second one. The fogs destroyed the first one. Good toy and great for applying peanut butter in the grooves.

Cute durable dog toy that my puppy loves
Color: Blue, Size: 8 IN
This small light weight dog toy is very durable, super cute, and my dog loves it. My dog tears everything up but he hasn't made a dent in this; very durable and chew resistant. He seems to really like that it makes a lower squeak noise. I threw this in my cart at the last minute before checkout and I am pleasantly surprised with the quality. I would say this toy is worth the price; suitable for small to medium sized dog.

Nice toy for a bigger dog
Color: Gray, Size: 6 IN
My little rescue chihuahua has exactly one toy he can make squeak. This one is cute and he did try, but no luck. I have two large baskets of toys I've bought in the 3 years I've had him. He is only able to make one squeak. He loves it to death because he loves the squeak. It's a hedgehog that I will try to find on Amazon and replace. Poor little dog just has a very small mouth.
