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.

Excellent quality chews. Tiny Puppy size is perfect for adult toy breed dogs.
Flavor Name: REAL Bacon, Size: Puppy (2-Pack)
I bought the Tiny Puppy Bacon flavor 2-pack package of these, and my dog and his sister are obsessed with them. They chew on them multiple times every day. They seem to be fairly durable, although I expect they will break down over time, which is okay as it’s a chew. I like that they stay intact, with no chunks breaking off for the dogs to swallow. The dogs do ingest a small amount as the material breaks down, but I always supervise them when they have these, and there haven’t been any problems. It’s difficult to find good chews for toy breed dogs like our 12-pound Shih Tzus, so I was happy to find these. They are pricey, but I believe they are worth it. The dogs love to carry them around, and my little guy even plays with his chew sometimes like it’s a toy.

Durable, engaging, and dog approved
Flavor Name: REAL Bacon/REAL Maplewood, Size: Puppy Tiny (2-Pack)
These chew toys are great for keeping dogs entertained and engaged, especially for gentle chewers. The quality feels strong and they hold up well compared to many other toys. The real bacon scent keeps dogs interested and coming back to them often. I’ve ordered multiple packs over time for my own dogs and even gifted them to others because they’re so well liked.

The "Y" is a staple! The other is useless.
Flavor Name: REAL Bacon, Size: Small – 2 Pack
Leaving a 4-star review because she has chewed this "Y-shaped" Benebone almost down to the nubbins. At first she didn't want much to do with it, but something clicked and once she started chewing it, it's become a staple in her chewing repertoire. But the other shape... the double-pull with the lines on it... is apparently not chewable for her. She'll tote it around, but won't really sink her teeth into that one. She's still a puppy, so maybe she'll start on the double-pull shaped one later. But we'll probably hafta get a larger Y-shape in a month or two... that one's totally worth it!

My dog lives these. Great for the puppy chewing stage.
Flavor Name: REAL Bacon/REAL Maplewood, Size: Puppy Tiny (2-Pack)
My dog loves these bones. I love them too because I dont have to worry about him choking in them or biting off small.peices. Great for puppies going through the chewing stage. My dog seeks these bones out over other toys. The size is great perfect for medium sized dog. Material is durable and lasting. Occupy my dog for a long time.
