Electrospinning (ES) is an electrohydrodynamic coating process that can “spin” continuous organic, inorganic or particulate/polymer blend fibers with nanoscaled diameters, typically in the range of 50 – 1000 nm. Electrospinning (ES) has been around for 20 years but has had limited commercial viability due to the low production rates of existing ES equipment, which impedes the prospect of using it for practical applications.

NanoStatics has developed a high production scale manufacturing process capable of producing composite products engineered with nanomaterials. The NanoStatics’ electrohydrodynamic spinning (EHS) process (Patent Pending) allows the forming of nanofibers of various polymers, inorganic materials, and blends of materials onto a substrate in a continuous web in a highly controlled process at uniquely high production rates.

EHS process nanofiber coatings are typically applied at 0.25 to 0.75 grams per square meter and achieve equivalent or improved performance to most conventional coatings applied at 10 to 15 times higher weight. The EHS coating system can apply coatings and surfaces consistently in this range.

Coatings can be applied to paper, fabric, metals, glass, film. wood or any flexible or rigid surface at throughput rates that can make it very economically attractive compared to conventional coating systems

Coating with a continuous web of nanofibers presents some very unique properties including:

Controllable permeability for gases, water vapor, liquids allowing very efficient separation of gas/liquid, gas/solid, water/water vapor, solid/liquid.
Achieving very high print density with ink jet, litho, gravure and flexographic inks.
Surface smoothing. The nanofiber coating is a semi – contour coating. Because of the bulkiness of the coating and continuous web, there is some filling of uneven surfaces and very effective filling of pinholes. Surface smoothness is typically dramatically improved.
Coverage and hiding power. The coatings have exceptional coverage and can make brown surfaces white or white surfaces black depending on the formulation.
Very high performance efficiency of functional coatings. Due to the fact that functional coatings are held directly at the surface and due to enhanced surface smoothness, typically, only 1 to 5% of the coating weight of functional materials needs to be used for equivalent performance.
The ability to incorporate particulates to create a tightly bound web of particulates, with considerably less binder material, in a 3 dimensional matrix that will allow air, water vapor, gas or liquid circulation through it. These particulates can be adsorbers, absorbers, catalysts, or other reactants.

Materials to be printed on using ink jet, litho, thermal, gravure, or flexographic printing

Composite structures of unique materials

An EHS coater can be compact since usually no drying is required because of the very low coating weights and drying component of the spinning process. For certain applications, it may be possible to put an EHS system on a winder, sheeter, printing press, packaging machine or other converting device and bypass the normal coating process.
