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.

Very good cleaning oil
This cleansing oil is ideal for sensitive skin, I suffer from rosacea and I had no problem using it, neither dryness nor redness, the skin is hydrated, soft and very clean even when you remove the makeup, remove all the rest of it. I recommend it.

This product needs better instructions for people that don't know what a deep oil cleanser is!!
I am new to oil cleansers/double cleansing. I purchased this with the toner pads and serum thinking i was doing something. I ended up with staph on my chin and jaw, bc NOWHERE on here nor the bottle does it say this is only meant to be used ONCE A DAY, and washed off with a gentle cleanser afterwards. ALL instructions say rinse with water and then use the other items in the line. I damaged my skin barrier and wanted to hide away for over a month. HOWEVER, now that I have gone to the lengths of figuring out what happened and educating myself and using this product the correct way for a few days, I am seeing slight improvement already. Just make sure you know how to use a deep oil cleanser when buying this bc i didnt!!

Nice starter skin care set that refined pores for a smoother and brighter complexion
This cleansing oil was purchased and arrived as a 3pc set that I have purchased. Along with this cleansing oil, it also came with the toner and closer pore reducing serum. I have been incorporating all three products into my daily skin care routine/regimen. So cleanse, tone, then moisturized. This cleanser is very gentle, and it leaves my skin feeling clean and refreshed after cleansing, to prepped it before I apply the toner and follow up with the Closer pore reducing serum as the last step. Overall, I really like this set. The Close serum has a thicker consistency than my other serum, but it applies well and also seem to absorbed fairly quickly, so it doesn't leave my skin/face feeling sticky.

Great product
Love, love this face wash, cleans well, no greasy feeling after using it, foams up good, and great quality, doesn’t really have a scent, but doesn’t smell bad, removes makeup and cleans pores well
