Making Nanoparticles Mega: Scaling-up the Synthesis of Gold Nanoparticle-Wool Fibre Composites

Nilsson T.W., Johnston J.H., Victoria University of Wellington and the MacDiarmid Institute of Advanced Materials, NZ

Gold nanoparticles exhibit intense surface plasmon resonances in the visible region of light. This property allows them to be employed as stable colourants for fine New Zealand wool fibres. A novel proprietary approach for the [...]

New Generation Hybrid Plastics Functionalised by Nanogold and Nanosilver

Pobedinsky M., Johnston J.H., Victoria University of Wellington, New Zealand, NZ

This paper reports on the synthesis of a new generation of hybrid plastics comprising polyurethane and nylon with gold or silver nanoparticles respectively, in a synergistic way. The gold and silver nanoparticles are prepared in-situ, [...]

New Fluorescent Hybrid Materials Comprising Quantum Dots, Organic Fluorophores and Natural Fibre Substrates

Zeller A.J., Johnston J.H., Victoria University of Wellington, NZ

The nanotechnology research presented here deals with the development and characterisation of new fluorescent hybrid materials comprising quantum dots and organic fluorophores respectively with wool and paper fibres that exhibit tuneable optical fluorescence and electronic [...]

Characterization of palladium nanoparticles embedded in a wool substrate

Fonseca-Paris C., Johnston J.H., Victoria University of Wellington, NZ

In the present paper we report the characterization of nanopalladium-wool fibre composites. Professor James Johnston and his research group at Victoria University of Wellington have developed a new methodology to reduce metal salts of palladium [...]

Silver Chloride – Wool Nanohybrid Materials: Synthesis and Properties

Johnston J.H., Kelly F.M., Victoria University of Wellington, NZ

The development and characterisation of a new nanowool hybrid material formed by functionalising merino wool with silver chloride nanoparticles is presented. The nanoparticles are formed directly on the surface and inside the wool fibre. Initially [...]

Nanopalladium – Wool: A Novel Fibre for Multifunctional

Fonseca-Paris C., Johnston J.H., Victoria University of Wellington, NZ

The development of new functional textiles based on composite materials of natural fibres and nanomaterials have become of increasing interest within both academic and industrial sectors. The inherent properties of their all precursor components can [...]

Gold Nanoparticles as Colourants in High Fashion Fabrics and Textiles

Johnston J.H., Richardson M.J., Burridge K.A., Kelly F.M., Victoria University of Wellington, NZ

Gold nanoparticles which exhibit different colours due to surface plasmon resonance scattering effects are used here as stable colourants on wool and synthetic fibres. This provides the exciting opportunity to link nanoscience with high value [...]

Novel Hybrid Materials of Cellulose Fibres and Nanoparticles

Small A.C., Johnston J.H., Victoria Univeristy of Wellington, NZ

The combination of organic and inorganic materials provides the opportunity to develop new materials that not only retain the inherent properties of their component precursors but may also exhibit new properties due to the synergistic [...]
