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.

For soft, sensually awesome sheets- LOOK no more!
Color: 15 - Sage Green, Size: Full
Would give 10 stars if possible! (And this is a nonpaid for review!) When I received the sheets, instantly I knew that I had the right ones, had bought a down comforter close in color as well.. these sheets? The material is strong yet, soft and warm. So so especially soft, and when I make up the bed, ahhh! plus the corners on the fitted, such a cinch to pull over the mattress, even with a topper on the bed! Feels almost spa-like <3 Very comfy, so far in the winter and in 85 degree heat! Soft and easy peasy to care for, too. Washing is a breeze, dry and fold. So far the only thing I can smell on these sheets is my wonderful detergent! Will purchase again. And possibly, again! Thank you!!

Color is exactly as advertised. Feels very soft, fits perfectly. No weird odor and not too warm 🥵. Only downfall I can tell is it seems a bit thin.

Very thin. You get what you pay for.
Color: 01 - White, Size: Queen
You get what you pay for. I first noticed the softness which was great. The quality is very thin. They are cool which is great. I have not washed them yet. I would suggest washing them on cool and gentle by themselves. And because they are so thin I would fluff dry for an hour if you have that setting. The two things that damages clothes and sheets, etc. are if you have an agitator in your washer, those ruin clothes and the heat you choose for the fabric you’re drying I always wash my clothes on cold. I do not have an agitator anymore and on delicate and thin fabrics, I use fluff dry. It is cool, but it will dry, especially if it is thin and I’ve had to dry my fine delicates a little bit longer on fluff that way they don’t shrink because the shrinking comes in from the heat from the dryer so keep that in mind another good thing to remember if you got white sheets like I did is that when you use your detergent add a little bit of borax or laundry booster and they will help get them clean and sparkly white. I am on the fence about whether I would recommend this or not if you’re tight on money and you take good care of them I would recommend that you get them. I’m a linen freak and I buy mostly expensive sheets and I thought I would try this out so that’s where I’m at.

Perfect Fit and Great Quality Sheet Set (10/10)
Color: Grey, Size: King, Color: Grey, Size: King
⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐ (10/10) This bedsheet has been working flawlessly and honestly exceeded my expectations. The fit is perfect on the mattress—it wraps securely without slipping or coming loose during the night. It stays in place even after movement, which makes a big difference in comfort and convenience. The fabric feels soft, comfortable, and well-made, giving a clean and fresh look to the bed. It’s also very easy to put on and remove, which makes washing and changing sheets much simpler. So far, there are absolutely no issues at all. Everything works exactly as it should, and it holds up really well with daily use. Overall, it’s a simple but high-quality product that does its job perfectly. I would definitely recommend it—10/10.
