Basic Info

What is 1H,1H,2H,2H-Perfluorooctyltriethoxysilane?

Organosilicon substances and the organosilicon materials made from them have a variety of varieties as well as outstanding efficiency, as well as have actually been widely utilized in industrial and also farming production, emerging innovations, nationwide defense as well as military sector, as well as various other fields. Hydrosilylation is among one of the most important approaches for creating Si-C bonds in organosilicon chemistry. Several organosilicon monomers as well as polymers consisting of natural functional groups can be manufactured via hydrosilylation. Silane combining agents are a course of low molecular weight organosilicon substances with special structures, with the general formula RSiX3, where R represents amino, mercaptovinyl, epoxy, chloropropyl, cyano, methacryloyloxy, and other groups. These teams have solid sensitivity with different matrix materials, and X represents teams that can be hydrolyzed, such as halogens, alkoxy, and also acyloxy. Therefore, silane coupling agents can connect with both hydroxyl groups in inorganic compounds and lengthy molecular chains in natural polymers, thus combining 2 products with different homes to improve the efficiency of biomaterials.

After hydrolysis, tridecafluorooctyltriethoxysilane launches reduced molecular weight alcohols, leading to energetic silanols that can chemically bond with hydroxyl, carboxyl, as well as oxygen-containing groups in lots of inorganic and also natural substratums, forming self-assembled monolayer fluorosilicone movies on the surface of not natural products.

1H, 1H, 2H, 2H perfluorooctanyltriethoxysilane is a fluoroalkyl silane mainly used to improve the wettability of substrates by reducing surface energy. It promotes superhydrophobic coatings by enriching CF3 groups on the surface and having a water contact angle above 150 °. Its wettability plays a role in repelling the aqueous electrolyte solution from the metal substrate, thereby protecting the metal substrate from corrosion. Used as an active ingredient in fluorine modified ORMOCER (organic modified ceramic) coating materials.

Application of 1H,1H,2H,2H-Perfluorooctyltriethoxysilane

Triethoxy-1H,1H,2H,2H-tridecafluoro-N-octylsilane can be used as an anti-fingerprint agent for high-grade mobile phone screens, camera lenses and other glass products.

A method for preparing a flexible carbon fiber with super-amphiphobic properties, comprising the following steps:

  1. Dissolve polyacrylonitrile and manganese acetylacetonate in N,N‒dimethylformamide to form a uniform electrospinning solution, and prepare nano-spun fibers through electrospinning technology.
  2. After the nano-spun fiber is pre-oxidized, it is placed in a nitrogen atmosphere for high-temperature carbonization to obtain manganese-doped carbon nanofibers.
  3. Soak the obtained manganese-doped carbon nanofibers in an ethanol solution of 1H, 1H, 2H, 2H-perfluorooctyltriethoxysilane (POTS) to obtain a superamphiphobic flexible carbon material.

The present invention prepares manganese-doped polyacrylonitrile uniform nanofibers by means of electrospinning technology and using N,N-dimethylformamide as a solvent. Then, after high-temperature carbonization treatment, a flexible nanofiber film carbon material was prepared, and the carbon fiber was characterized by means of a scanning electron microscope. It can be seen that the surface of the fiber has a certain roughness. Soak the carbon fibers in 1H, 1H, 2H, 2H-perfluorooctyltriethoxysilane (POTS) ethanol solution, dry and cool for performance testing. The test results show that the flexible carbon fibers have certain superamphiphobic properties. properties, and has important applications in the field of superamphiphobic and self-cleaning materials. The process is simple, the shape of the spinning fiber can be adjusted, and it is green and environmentally friendly. The average size of the spun carbon fiber is 300-450 nm, and the prepared carbon fiber with superamphiphobic properties exhibits a contact angle of about 155° and a rolling angle of about 4° at different pHs. The contact angle to different oils is about 152°. The flexible carbon fiber with superamphiphobic properties prepared by the method of the present invention has the advantages of light weight, bendability, easy portability, low production cost, etc., and can expand the application field of superamphiphobic interface materials, such as coating on the hull of ships, fuel On the storage tank, it can achieve anti-fouling and anti-corrosion effects; when used in the transportation of oil pipelines, it can prevent oil from adhering to the pipeline, thereby reducing energy loss during transportation; modify textiles with super amphiphobic materials; and in construction and The glass used in automobiles requires that it must have functions such as waterproof, anti-fog, self-cleaning and low radiation.

Contact treatment
If tridecafluorooctyltriethoxysilane is inhaled, move the patient to fresh air; if in contact with the skin, remove contaminated clothing, rinse the skin thoroughly with soap and water, and seek medical attention if you feel unwell; In case of eye contact, eyelids should be separated, rinse with running water or normal saline, and seek medical attention immediately; if swallowed, rinse mouth immediately, prohibit vomiting, and seek medical attention immediately. Advice to protect rescuers is as follows: transfer the patient to a safe place, consult a doctor, and if possible, please show this chemical safety data sheet to the doctor on site.

Leak handling
In case of leakage, if a small amount of leakage occurs, collect the leakage liquid in a sealable container as much as possible, absorb it with sand, activated carbon or other inert materials, and transfer it to a safe place. For containment, close the drainage pipe, cover it with foam to suppress evaporation, transfer it to a tank truck or a special collector with an explosion-proof pump, and recycle it or transport it to a waste treatment site for disposal.
