P2i is a nano-coatings technology company, operating internationally, which has developed a family of patents in liquid-repellent nano-coatingsnano-coating technology based upon UK defense research.[1] The technology can be adapted to provide a range of treatments for different applications. P2i’s nanotechnology is a super-thin coating (it’s less than 30nm thick, about 1000 times thinner than a human hair) for electronic devices that essentially make them liquid- and stain-repellent. P2i says it’s the leader in liquid-repellent nano-coating technology, over 7 million hearing aids currently feature the technology.

The company’s platform technology is based on original PhD research [2] carried out in the late 1990s by P2i’s Chief Technology Officer, Dr Stephen Coulson, within the Functional Surfaces group led by Professor Jas Pal Badyal at Durham University [3]

The technology grows a highly hydrophobic, nanoscopic (40-80 nm) polymer layer, based on perfluorinated carbon compounds, over the entire surface of an object, through the action of a special pulsed, ionized gas plasma, created within a vacuum at room temperature . The nano-coating has the effect of lowering surface energy, down to one third that of PTFE (polytetrafluoroethylene), which in turn imparts hydrophobic properties.[4]

Video footage shows that water and other liquids form beads and roll off when placed in contact with nano-thin polymer treated products [5] P2i claims the process attaches the polymer with covalent bonds and becomes part of the surface of the material it is attached to [6]

P2i claims that its nano-coating technology can impart or enhance liquid repellency with a diverse range of materials, including polymers, metals, fabrics, leather, ceramics, glass and paper. It also claims that the nano-coating is effective in protecting complex, 3D objects incorporating several different materials, thanks to the gas-phase operation of the polymerization process [7][8]

Coulson’s research project was funded by the DSTL which wished to protect clothing from water and other liquids while maximizing comfort. P2i Ltd was established as a stand-alone company in 2004, as the first DSTL technology spin-out managed by Ploughshare Innovations (the DSTL’s technology transfer company)[9]

On 13 July 2010, P2i announced the acquisition of Surface Innovations Ltd, a UK-based technology company with several functional nano-coating patent families in areas such as anti-bacterial resistance and liquid attracting (super wettable)[10]

According to P2i’s website, current applications for its technology are in the categories of ‘Electronics, Lifestyle, Life Sciences, Filtration & Energy and Military & Institutional’ [11] For consumer-facing products the company has created sector-specific trademarked brands. The ion-mask brand [12] is used in lifestyle products such as footwear, outdoor clothing and accessories (gloves and headwear). ion-mask products are on sale from several international footwear companies including Timberland,[13] Nike,[14] adidas Golf,[15] Hi-Tec,[16] Magnum Boots,[17] Van Dal,[18]Teva,[19] and K-Swiss.[20]

The Aridion brand,[21] is used in consumer electronics, focusing initially on the hearing aid sector where the company now claims to have processed over 5m devices.[22]


P2i Ltd has a head office on the MEPC Milton Park campus near Oxford, UK,[23] but there are also two wholly owned subsidiaries in the US: P2i Inc and P2i Processing Centres Inc.[24] These operate across two US facilities: a US Technology Center based at the Herty Advanced Material Development Center in Savannah, Georgia;[25] and a US Processing Centre based in Beaverton, Oregon.[26] On 14 September 2010, P2i announced the opening of an office in Singapore to serve the ASPAC region.[27]
