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.

My favorite robot vacuum! Works awesome!!
Size: 11S MAX, Size: 11S MAX
Eufy is by far my favorite robot vacuum brand we had one for several years and it did amazing with everything from dust to hair and even rocks didn’t phase it! It is super easy to set up, turn on, the settings are very user friendly and emptying the dust bin is super simple! They are very powerful but also compact and can fit in smaller places so that’s great for us and even when I don’t think there’s much on the floor it always gets full! You honestly can’t beat the price for how great these awesome little vacuums work definitely get your value for your money! I was a little skeptical getting the refurbished or Like-New one but I am super impressed so far! So grateful for tools like this to have around that are great at lending a hand 🤩

Sort of OK Budget model
Size: 11S MAX
I'm giving this model 5 stars because at this price, especially "renewed," it's a great robo vac. It is NOT anywhere near the hands-off level of other machines. It can't map the rooms, bumps its way around fairly successfully, but needs frequent hands on to fix something. In my case, with 2 long-haired cats, the most frequent issue is tangled hair in the roller. The machine stops dead and sends out 4 beep distress sounds for a while, then shuts down. Also, the remote seems to work only in line of sight, so if Eufy is stuck somewhere you can't see, and you were out, to find it you'll have to hunt with your eyes. Nevertheless, if your funds are limited, top choice. Update: After 6 months of usage, I'm giving it only 3 stars. Problems: 1) if you have long-haired cats (I do) their hair clogs the roller fairly quickly. After a while, no matter how well you clean the hairs out, you have to replace the roller entirely as hair seems to get inside it and cause the machine to stop working entirely. 2) the remote works only if you can see Eufy and it can "see" you. If it gets stuck in some place out of sight, lots of luck finding it. 3) when told to go to home base and recharge, it bumps around for a long time trying to find the way home. Bottom line: Where it vacuums the rug/floor is clean, but it takes a lot of baby sitting. Definitely not first choice unless funds are really tight.
