Our technology – Nano Hybrid Spray NT™™

Hybrid spinning is a new technology using a combination of several known principles (electrostatic, pressure and centrifugal) for the production of nanofibrous membranes in one process step.

In July 2022, we filed a patent application for a new spinning technology that provides the enormous variability necessary for the development of specialty composite membrane materials.

The device not only produces a simple or layered membranes from different polymers, which is common for most commercial technologies, but also enables production of unique combinations of different polymers in one or more layers, using a combination of different spinning principles.

The dual hybrid spinning system is able to form fibers of two different (solvent-incompatible) polymers at the same time and arrange them into one mixed layer.

Another option is the simultaneous production of fibers and particles, in which the fibers form a matrix carrying the incorporated particles. The production of multi-component fibers is a matter of course. By this way, an abundant number of polymers can be combined in the fiber layer, including those that cannot be processed together by other spinning techniques.

What kind of nanofibrous membranes can we produce?

1) Single-layer nanofibrous membranes

In this case, it is a simple membrane made of one polymer. Two spinning chambers are used to increase the production output of the device and higher productivity. 

2) Double-layer nanofibrous membranes

Double-layer nanofibrous membranes are made of two different polymers and they are used, for example, in cosmetics, where each of the layers has a different function. One of the layers is solid, insoluble and it works as a carrier and it helps fixation on the skin and the penetration of active substances into the skin, the second layer is soluble in water and it contains active cosmetic substances. 

What is it used for?

Double-layer membranes can be used in cosmetics, but also in the healthcare sector for wound dressings, where one layer protects against the penetration of microorganisms from the outside, while the other helps to stop bleeding or accelerate healing. This way may be used for example for production of improved filters and respirators, more sophisticated wound dressings and cosmetics.

3) Single-layer blend nanofibrous membranes

A dual spinning system is used to produce a single-layer blend nanofibrous membrane. Two different types of fibers are spun separately from different parts of the spinning head, which are deposited together on the substrate and form a blend layer. In this case, two spinning chambers are also used to increase productivity. 

Different types of fibers from different solvents can be combined, which cannot normally be mixed and spun together from one solution, because they either do not mix or react with each other. While other commercial solutions only offer layering, our technology comes with a blend of different fibers. One type of fibers may be thicker to provide mechanical properties, other type may be thinner to bringing better filtration. 

It is also possible to combine the production of fibers with the formation and deposition of particles. Instead of particles, a cross-linking agent can be deposited on the surface of the fibers, which causes a cross-linking reaction and thus transforms, for example, water-soluble fibers into water-insoluble fibers and thus saves one technological step of the production process. 

What is it used for?

Its use can be found in drug and catalyst carriers, cosmetics, sophisticated wound dressings, tissue engineering and energy devices.

4) Double-layer blend nanofibrous membranes

During production of the double-layer blend nanofibrous membrane, two dual spinning heads are used, the device produces two different blend layers. In total, the composite may contain up to 4 different types of fibers or particles from 4 different materials. 

What is it used for?

This combination may find use in wound healing and drug carriers. Each of the 4 materials can have a different solubility and gradually release different drugs from the structure in a controlled manner with different kinetics, without the drugs interacting with each other. Various detection and sensor applications, cosmetics, catalysts, sorbents, tissue engineering and energy applications are also useful.

5) Single-layer composite fiber membranes

Composite two-component fibers can be obtained by spinning mixed spinning solutions, i.e. a mixture of two different polymers dissolved in the same solvent system. In addition to polymers, fibers can also contain various dopants, i.e. additives giving them some function. The use of both spinning heads again increases the productivity of the device.  

What is it used for?

Use can be found in carriers of active substances such as pharmaceuticals, cosmetics or catalysts, from which the use in sophisticated wound dressings, detection and sensor applications, sorbents, tissue engineering and energy applications is derived.

6) Double-layer composite fiber membranes

This method, in which each dual spinning head produces different composite fibers, allows the production of two different layers with different composite fibers. In total, the composite can contain 4 different polymers processed into two types of composite fibers. Each of the layers can contain active substances with different functions and kinetics of their release. 

What is it used for?

It is suitable for detection and sensor applications, cosmetics, catalysts, sorbents, tissue engineering and energy applications.

7) Double-layer blend composite membranes

Extrémní možností využití této technologie je kombinace zařazení obou duálních systémů a směsných zvlákňovacích roztoků. Pak vyrobený kompozit může obsahovat 8 rozdílných polymerů zpracovaných do dvou typů směsných vrstev, přičemž každá vrstva obsahuje směs 2 typů kompozitních vláken. Výsledkem je pak velmi složitý kompozitní systém s širokou variabilitou, jež nenabízí žádná z dostupných komerčně nabízených technologií.

What is it used for?

It is suitable for detection and sensor applications, cosmetics, catalysts, sorbents, tissue engineering and energy applications.
