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.

Glad I chose these Sturdy, Fluffy Pillows
Color: White, Size: 18x18 Inch
Took me forever to decide which pillows to buy....Price won out. There might be better out there, but I really can't see how. They plumped up really nicely. I once learned from a manager at a big box dept store when purchasing a goose down pillow how to 'activate' the pillow. Basically, he violently threw the pillow down onto the floor, then proceeded to beat the tar out of it....That's how it's done. I think many ppl don't do a good enough job when they get their pillows. I watched several videos from ppl who have purchased this type of pillow. And quite frankly, they do not know what they are doing....My pillows are very plump and awesome. I purchased the 20" squares and then chose 18" pillow covers to stuff them into. Perfection. Fat, soft, soothing pillows. Me and my Doggo are quite happy to lounge around on these durable puffs of fluffiness.

Excellent Inserts. Great price point.
Color: White, Size: 12x20 Inch
I purchased the 20x20 first and loved them so much, I purchased these the next day. They come vacuum sealed so please do be careful opening them. It takes a little time and patience. These fluff up so nicely. I manipulated by hand a bit then into the dryer with wool dryer balls on medium heat for about 20 minutes. They are odor free which is a big plus for me and the quality is there for the price. I can't use feather inserts for anything so these are the next best I've found at this price point. I will be purchasing more and I do recommend.

Fluffy and Supportive Pillow Inserts
Color: White, Size: 12x20 Inch, Color: White, Size: 12x20 Inch
I used these pillow inserts for my couch cushions, and they’ve worked out really well. They give my throw pillows a nice full look without being too stiff or flat, which makes the couch feel more put together and comfortable. Filling quantity: They’re nicely filled and give good shape without feeling overstuffed. Durability: They seem well-made and hold their shape well even after daily use. Color: Clean, bright white that works well with different pillow covers. Appearance: They make my decorative pillows look fluffy and full, giving the couch a more finished look overall.

Exactly what I was looking for
Color: White, Size: 26x26 Inch
I bought these to fill some euro pillow covers and they worked out really well. They come vacuum packed, so at first they look flat, but once you open them and give them a little time, they fluff up nicely. They are soft but still have enough structure to hold their shape on a bed or couch, which is exactly what I was looking for. Not overly firm, but not limp either. They give that full, styled look without feeling stiff. The size is true to 26x26 and fills the covers well without looking saggy. I like that they don’t feel hollow like some cheaper inserts can. Quality feels good for the price. They are not luxury pillows, but definitely a solid option for decorative use and they hold up well. Overall, really happy with them and would buy again for other rooms.

Smells amazingly like cherry, but expect a mess under the feeder.
Style: Wild Bird Food, Style: Wild Bird Food
This is a fantastic budget seed blend to keep your backyard feeders full during the busy seasons. I put a banana in the picture next to this massive 10-pound bag for scale, though I wouldn't recommend leaving the fruit out there unless you want to feed the local raccoons instead. The most surprising part of this bag is the smell—it has a very strong, sweet cherry scent right out of the bag that genuinely seems to bring in the local cardinals and blue jays faster than plain seed. THE GOOD: • The cherry flavoring actually works as an attractant, and the sheer volume of seed you get for the price makes this an excellent value for high-traffic yards. • It brings in a huge variety of ground-feeding birds, especially mourning doves and juncos. THE TRADE-OFF: • This is a "value" mix, which means it contains a very high percentage of filler seeds like milo and cracked corn. Finicky songbirds will actively kick the milo out of the hanging feeder to get to the black oil sunflower seeds, creating a massive pile of rejected seed on the ground. THE BOTTOM LINE: A great-smelling, budget-friendly birdseed that attracts a ton of wildlife, provided you don't mind the ground-feeders cleaning up the mess underneath.
