Queensland University of Technology (QUT) scientists have developed a new technique for dispersing metals in nanoparticle form throughout polymers or plastic materials.
The properties of metals change when they are in nano form. When nanoparticles are added to plastics, a new range of composite materials are formed.
When gold nanoparticles are added to paint, essentially a plastic, the intensity of colours and durability are increased.
Mixing gold nanoparticles with titanium dioxide, TiO2, using a plastic mould makes a very efficient catalyst for water purification as the titania absorbs light, converting it into electricity which is then passed into the conductive gold.
