New Path Of Nanofibers

P, NCSU has recently developed another technology for producing nanofibers, which is jointly completed with the company of Senofi (Xanofi).

It is said that this technology has opened up more applications for nano end users.

The company also said that they developed the world's first high efficiency, liquid based platform for nanofiber production, which is currently being optimized for improvement in order to increase production.

< p > as early as 2000, molecular biology experts at North Carolina State University developed nanofibers using the principle of polymerized microfiber colloid in chemical laboratories.

Sanofi has successfully produced nanofibers and non-woven fabrics, and has also developed dry wet jet production technology.

Subsequently, they discovered in practice that the formation of nanofibers is completely different from that of melt blown and electrospinning. The latter's production is based on dry continuous fibers, while the XanoShear process is based on liquid working conditions, and the fibers produced can disperse in water and become nets and solidified into finished products on existing equipment.

Other advantages of XanoShear include scalability, fiber coated functional processing, and closed green production systems that use less energy and do not discharge any harmful substances into the environment.

At present, from research and development to commercial production, Sanofi can provide a complete range of semi-finished products for customers, and is successfully used for medical treatment, filtration, sound absorption and energy saving.

< p > this method of production takes advantage of the combination of solvent and non solvent to force the soluble polymer to be separated into solid state.

At the same time, when it changes from liquid to solid, it forms micro nanoscale into fiber during stretching.

< /p >

< p > nanofibers produced by this method have several advantages.

First, the electrical jet filament fibers were first applied to the surface, while the XanoShear forming fibers were distributed in liquid, forming a 2-D or 3-D medium, and a discontinuous fiber material was created.

Its applications range from 3D printing materials to food processing, to liquid or air filtration and ion exchange chromatography.

Of course, this technology does not mean that the main production methods of nanofibers can be replaced, namely, EFI and melt blown methods. It shows that different nanofiber products can be developed by different methods.

Of course, these products are more suitable for making 3D printing materials.

< p > it is worth noting that the production principle and equipment of this material are very simple.

XanoShear? Starting from the test tube technology.

Developers thought that commercial machinery should be as large as a large washing machine, but in fact it was not.

At first, they put forward 12~13 different production methods under the continuous liquid flow state. But one day, they discovered something unexpected. They discovered that the original XanoShear, which needed a lot of equipment to complete the production, could be completed with a sprayer size equipment.

They really did, that is, using this sprayer to produce nanofibers.

Of course, this can not be accomplished overnight, because mass production requires continuity.

Soon, they found a container equivalent to the size of a beer barrel and installed the nozzle to start trial production.

At this point, dramatic creation took place.

An automated test facility was launched quickly based on the basic principles of nanofibers, and was the first to introduce multi-functional automatic production equipment and to pform more spherical handles based on the production of different materials.

As a result, production is expanding.

It quickly formed a prototype of the platform that could produce many different nanofibers.

The company developed a new hardware system for nanofiber production and was soon supported by the National Science Foundation of the United States.

< p > despite the fact that the news came out, the company received a large number of orders, but they did not sell machine equipment and nanofiber products. Instead, they planned to adopt a commercial mode to find business partners to help themselves develop more products.

They do not want to turn themselves into equipment suppliers, and do not want to turn themselves into "WAL-MART" of nanofiber products; if so, it means they need huge sums of money to build infrastructure.

What they should do most is to sell patents at commercialized prices, and find more new applications for this material.

The reason is that they have their own unparalleled development platform.

What they expect is to complete 80% to 98% terminal production and then to enter the market directly through another simple production process.

They all have intellectual property rights, and the only thing they need is a commercial sales partner.

The product was released in February 2014.

< p > < strong > the first product of the new nanofiber is < /strong > < /p >.

The first nanofiber product developed by P is called XanoMATRIX, which is a 3D honeycomb production framework with independent paths. It can automatically expand and deform according to requirements.

In collaboration with the North Carolina State University, they also cooperated with University of London and University of Cambridge to develop similar products.

Another product developed by Sanofi company is called 6C chain fluorinated product, which is an additive which is mainly used to improve the hydrophobicity of P fibers.

Because its hydrophobicity is less than 30%, it can recover 80% hydrophobicity by chemical modification.

C6 chemical additive production process is simple.

If combined with another additive, C6 can regain 95% of the efficiency, but the price is very low.

Other related products are also being developed, including corn gluten for food processing, which is called life science product.

It is developed by affinity chromatography.
