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: ~1440 m2/g

Pore size:~3.63 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.

Durability
Color: Pink
My dog absolutely loves playing with this toy!! It is made of very thick plastic and I’m thinking she won’t be able to destroy this toy very easily!! She loves for you to throw it and play tug of war with. I’m very pleased with my purchase. She is a medium size dog and it works great for her.

Well made, minor issue was quickly resolved
Size: Large, Color: Dinos Bruto (Purple)
I purchased the Dino Bruto Dog toy for my labradoodle who is quite fond of squeaky, squawky stuffed toys and oddly enough has shown a preference for purple. I opened the package with my hound standing by waiting for his gift. I detached the tags and attempted to squeak the toy. It seemed difficult to squeak or honk. I tossed the purple Dino Bruto to my dog who excitedly chomped to squeak. The toy squawked a couple times and then just quit. My poor hound was staring up at me with that "what's up with this" look on his face. I tracked down the website for the GoDog toys, not going through the Amazon return process. I called the good people at GoDog and stated simply that my dog's favorite part of the toy failed quite quickly and I was wondering about guarantees. I was told to go to the website and file a replacement request. The replacement request required that I include a photo which I did as directed. I received an reply email within a couple hours which stated that a new toy would be sent out shortly. I am happy to report that we received a replacement toy, not the purple Dino, but a colorful wood duck. The squawker device works well and is still performing like new more than a month later. It appears that the squeaker is not those little plastic squeakers but the bigger heavy plastic bag, bladder, with what I visualize as a duck call sort of sound device. I am guessing because I haven't seen the inside of the GoDog toys. I have seen the guts of other stuffed toys which use this type of noise device. While our dog seems to enjoy the sound of the plastic bag, bladder set-up squawkers, they seem to fail quickly and I tend to avoid them because of this. The toys using this type of squawker that I have seen, use what looks like a cheap lightweight plastic bag which is not securely attached to the "voice box". Since the GoDog replacement toy is holding up so well, I am guessing GoDog uses a heavier grade plastic bladder coupled with reinforced construction. The purple Dino Bruto toy still looks new even after multiple times of our hound grabbing the purple toy, shaking it at us with his invite to give chase or play keep away. Since the squawker failed so quickly with the new toy, I figure it was just a defective item which does not reflect the general quality of toys from GoDog. One evening our neighbor was visiting while his pitbull was playing in our yard with our dog. Our patio door was open so our dog ran into the house and grabbed his purple Dino Bruto toy. He is a bit of a show-off with new toys. Our dog then went racing back into the yard, shaking his GoDog toy at the pitbull. A quick game of tug-of-war ensued. Since this is a new toy, our neighbor leaped into the game and took the toy away from the dogs. In that short time of tugging between the dogs, the toy held together and did not even pull apart at any of the seams. There were no puncture marks either. This is a game our dog has initiated before with the neighbor pitbull. Normally, the stuffed toys are ripped apart almost immediately. I was surprised and impressed with the quality of the sewing which appears to employ some sort of reinforced construction or heavier material. I plan to make more purchases from GoDog toys. The toys are a little more expensive than some stuffed dogs toys but they hold up so well I figure they are worth a few more dollars. They are great toys that hold up well and the company provides quick responses to inquiries. I consider this a winning combination.

Good quality
Size: Large, Color: Dinos Frills (Gray)
we’ve had many godog toys over the years and although my dog eventually rips through them I do find that they last longer than other cheap toys. Overall very well made!

Cute and fairly long lasting
Size: Large, Color: Dinos Frills (Red)
Lasted from Nov 13th, 2024-August 20th, 2025 lol very impressive. She played with it nearly daily and loved the big squeak. The squeak box was just ripped out so she probably won’t play with it anymore. Happy to order another!
