Nanoparticles are increasingly used in consumer and structural polymeric products to enhance a variety of properties. Under the influence of environmental factors (e.g., ultraviolet, moisture, temperature) and mechanical actions (e.g., scratching, vibrations, abrasion), nanoparticles could potentially release from the products and thus have negative effects on the environment, health and safety. Over the last 5 years this event has provided the world's leading forum on this subject featuring presentations from leading researchers in industry, academia and government laboratories. Focus areas include:

Nanoparticle release during the life cycInvited Sple of consumer products & nanocomposites
Durability of Nanoparticle composites under environment stresses (UV, Temp, Humidity, mechanical - scratch, abrasion, sanding)
Metrology for characterizing nanoparticle release and changes in nanocomposite properties
Applicability of standard test methods and measurement protocols for nanocomposite weathering and nanoparticle release
Potential toxicological effects from released nanoparticles
