HDIAC SOAR Webinar: Uses of Nanotechnology on Surfaces for Military Applications


Military Nano V uavThe Homeland Defense and Security Information Analysis Center (HDIAC) is a Department of Defense (DoD) sponsored organization through the Defense Technical Information Center (DTIC)

• HDIAC utilizes expertise and knowledge from government agencies, research institutions, laboratories, industry and academia on topics relevant to the DoD and other government entities to solve the government’s toughest scientific and technical problems

• Develop two State-of-the-Art Reports each year on a pressing topic related to the Defense community within HDIAC focus areasMilitary Nano IV 0

• Manipulation of matter on a scale of 1 to 100 nanometers (nm) in at least one dimension to create new structures and materials

• The modification of surfaces is fundamental to engineering and technological innovation, because almost everything about a product or device can be affected by its surface functionality and interaction with the environment.

Applied Nanotech puts Printed Antennas into Armour Composites: Protecting Vehicles and Troops


Army War2 071415A development project headed by US firm Applied Nanotech has successfully integrated printed electronic antennas into bomb- and bullet-resistant armour panels intended for military vehicles.

The work has been conducted with Armortex, an existing Texas-based supplier of composite armour systems into the defence industry.

Additional antenna design and modelling expertise was supplied by academics based at the University of Tennessee (UT) in Knoxville and Pennsylvania’s University of Villanova.

Applied Nanotech has built the wideband antennas in two designs. These have been tested and found to be satisfactory when built into fibreglass-based armour panels supplied by Armortex.

The Aussie Company That’s Using Nanotechnology to Protect the US Military


south-africa-ii-nanotechnology-india-brazil_261.jpgAlexium [ASX:AJX] [OTCQX:AXXIY]  is a Perth-based chemical development company with offices in South Carolina.

This morning, they announced a deal that will see them supply US military forces with leading edge flame retardant fabrics.

Alexium has developed a chemical called Alexiflam™. It’s used as a fabric treatment, to make that fabric flame retardant. It’s marketed under different names, depending on which fabric it’s meant for. Ascalon™ is for nylon, Nycolon™ is for nylon-cotton blend fabrics, and Nuvalon™ is for poly-cotton blends. The exact way it works is a bit hush hush, for obvious reasons, including the fact that they supply the military. But if you have a look at their US patent application, the abstract says:

‘An enhanced protective cover includes a top and bottom textile layer and an air permeable, moisture-vapor-transmissive, expanded polytetrafluoroethylene membrane layer located between the two textile layersThe protective cover also includes a top layer coating or fibre treatment of a nano-ceramic material designed to increase the durability of the cover.

Alternatively, the upper layer of the protective cover may incorporate ceramic coated fibers or ceramic co-extruded fibers, or carbon nanotubes. The protective cover may also feature a fire resistant application. The top textile layer may also include a permanent, highly breathable and highly durable electro-static discharge feature added to the inside of the layer by laying down a carbon based printed pattern on the inside of the layer.’

They’ve also got an Australian patent, which was granted in 2012. This patent explains how the coating sticks to the fabric. It’s pretty dense reading, but you can check it out here.

So basically, they’ve got a very broad, very detailed patent application to cover fabric treatments which create multi-layered protection. The ‘durability’ thing is part of what the military is after. They don’t want anything that’s easily scratched, melted, or transferred onto other surfaces.

Alexium orders to ship Alexiflam™ to Greenwood Mills in huge quantities. Greenwood Mills is a 115-year old company that makes fabrics for the United States Military, amongst other things.

Alexium already has strong links with the US military. For example, in December last year, they announced that they’d got a contract to make a new and improved flame resistant uniform for the US Department of Defense (DoD). In 2013, tests at a DoD-sanctioned facility showed an Alexium product (‘Cleanshell’) effectively repels live chemical warfare agents like sarin gas and mustard gas. That same year, they won a contract to supply the US Marines to develop fire-retardant fabric treatments. Other contracts came before that. In fact, Alexium has a whole affiliate — Alexium Government Solutions — to deal with military contracts.

But this deal is especially important. The president of Alexium, Dirk Van Hyning, explained why. He said that ‘Whilst we have a strong and healthy business in the commercial sector, the sheer size of the Defense market and the fact that our chemistries clearly fit with the stringent performance requirements for military grade FR [flame retardant] fabrics, makes the Defense sector another strong market for Alexium both in the US and internationally. This new customer, with operations in the Defense sector, is a key part of that overall strategy.

Alexium CEO Nicholas Clark thinks it’ll also be good for their penetration into the commercial market. Greenwood Mills also makes things like denim for big American brands including Levi Strauss, Abercrombie & Fitch [NYSE:ANF], and Hollister.

So there you go — in a few years, you could be wearing military-grade super-jeans that can stand up to chemical warfare and make your bum look good.

Clark said that ‘This new customer shows not only the continuing growth in the range and size of our sales but also the increasing rate at which new orders are being received as the market in both the commercial and defense sectors become increasingly aware of the performance and cost benefits of our award winning environmentally friendly FR solutions.
