Will nanomaterials define our future?
Dr John RobinsonCompetency Leader
Outline
• What are nanomaterials?
• Commercialisation case Studies
• What might the future hold?
• Conclusions
• A Materials Science approach to Nanotechnology• ‘Nanomaterial’: at least 1 external or internal
dimension at the nanoscale (less than 100 nm)• 1 nanometre = 10-9metre (million times smaller than a millimetre)
• eg: Nanoparticles, nanotubes, nanorods, thin films, nanostructured materials.
What are Nanomaterials?
Nanoparticles Nanorods Nanostructured particles
• Compared to traditional materials, nanomaterials:• Have increased surface area• Are potentially:
• Harder, stronger, more flexible• Often present:
• Unique optical, electronic, thermal properties• Nanomaterials are not new:
• Carbon black, photographic silvers, Ming Dynasty glazes
• ‘Nanohype’ began in 1990’s with advances in electron microscopy
Why are Nanomaterials of interest?
Potential Nanomaterials Applications
But products don’t always develop along the lines we expect…
Case Studies
• Antaria Limited
• Advanced Materials development & manufacturing company
• Based in Western Australia
• Technology start-up company, established 1997, initially
focusing on nanomaterials
Case Studies: Cerium Oxide
10 nm 20 nm 50 nm
• Nanoparticulate cerium oxide synthesized by Mechanochemical Processing
Case Studies: Cerium Oxide• Precision polishing of microelectronic components
(Chemical Mechanical Planarization: CMP)• Cerium oxide believed to be next generation CMP
material• Samsung Corning (SSC) invested $6m in 2000• Pilot plant constructed to demonstrate scalability of
process• Result:
• Nano cerium oxide unable to displace lower cost silica based CMP slurries• 2013: cerium oxide based slurries account for <1%
CMP market• CMP slurry project dropped…
Case Studies: Cerium Oxide• Antaria approached by Oxonica in 2003:
• Dispersion of cerium oxide nanoparticles for diesel fuel additive?• “Envirox”:
• Fuel borne cerium oxide nanoparticles act as combustion catalyst• Improves efficiency of combustion of diesel fuel• Assists in burning of carbon deposits
• Envirox now marketed by Energenics EU: utilized by Stagecoach Bus Co.
Case Studies: Aluminium Oxide• Micron sized plate-like alumina particulates with nanoscale
thickness
Case Studies: Aluminium Oxide• Applications initially pursued:
• Hard coatings• Advanced ceramics
• Toughening ceramics / glasses• Specialty lubricants• Transparent polymer additive:
• Improved strength• Reduced friction
• Result: unable to compete on price in comparison with existing materials / additives…
Case Studies: Aluminium Oxide• “Alusion” developed by chance:
• Functional cosmetics pigment:• Soft focus effect with enhanced cosmetic ‘feel’
• Technology licensed to Merck KGaA in2009:• Alusion incorporated in cosmetics pigments range
• “RonaFlare White Sapphire”• Collaborative R&D aimed at development of pearlescent
pigment products for automotive and other applications.
Cosmetics: a surprising market?• Antaria now focus entirely on Aluminium
Oxide and Zinc Oxide for cosmetics & sunscreens.
• Nanomaterials in cosmetics estimated at $155.8M end 2012• Ref: BCC NAN017D
• Nano ZnO & TiO2 UV absorbers in Personal Care estimated at $280m by 2015.• Ref: BCC NAN031D
• Where else can nanotechnology go?
What does the future hold?• Current global nanomaterials market size?
• $1.7 Billion in 2010 / growing 23% pa to 2016
• Ref: Global nanomaterials opportunity and emerging trends, Lucintel
report, March 2011
• $9.9 Billion in 2010 / growing at 14.7% pa to 19.6 Billion in 2015
• Ref: Nanotechnology: a realistic market assessment, BCC report
NAN031D, July 2011
• Depends how the market is defined
What does the future hold?Anticipated global nanotechnology market segmentation 2015
• $1.7
Estimated market size $19.6 billion in 2015: Ref: BCC NAN031D
What does the future hold?Graphene: next generation nanomaterial?
• Discovered 2004, University of Manchester (Nobel prize 2010)
• Chicken-wire type structure of C-atoms, single layer thick.
• Properties:• Hard as diamond• Flexible as rubber• Exceptional electric and thermal conductivity• High surface area• Transparent

What does the future hold?Graphene: next generation nanomaterial?
Global graphene market tipped to reach ~$520 million by 2020(BCC AVM075A, Feb 2011)
Conclusions• A bright future for nanomaterials?
• Challenges:• Cost competitiveness / performance advantage• Nanomaterials safety: Regulatory hurdles
• It seems safe to conclude:• Nanomaterials markets will continue to grow• New nanomaterials will continue to emerge
• The 3 E’s will to continue to dominate:• Electronic / Energy / Environmental
• $Billion opportunities
• Highest growth in healthcare & consumer goods• Antibacterial applications / Cosmetics…
• $100M opportunities
