Templated growth of smart nanocomposite thin films: Hybrid aerosol assisted and atmospheric pressure chemical vapour deposition of vanadyl acetylacet…

2009

Hybrid aerosol assisted and atmospheric pressure chemical vapour deposition methodology has been utilised to produce nanocomposite thin films of gold nanoparticles and vanadium dioxide from vanadyl acetylacetonate and auric acid. The addition of tetraoctyl ammonium bromide (TOAB) to the precursor Solution gave control of the size and distribution of gold nanoparticles in the vanadium oxide matrix. These reactions led to vanadium dioxide films with reduced crystallite sizes and enhanced thermochromic properties. The films were analysed by X-ray diffraction, scanning electron microscopy and X-ray photoelectron spectroscopy. Their optical and thermochromic behaviour was also determined, This h…

NUOVI VETRI TERMOCROMICI: ANALISI DEI CONSUMI ELETTRICI NEL MODELLO DI UN EDIFICIO (NEW THERMOCHROMIC GLAZING: ENERGY CONSUMPTION ANALYSIS IN A BUILD…

2009

In this work we tested the energy performance of the new thermochromic glazing developed at the University College London (UCL) under the supervision of Prof. Ivan P. Parkin. The aim of this study is understanding how efficient these coating could be if applied in several climate conditions at different latitudes in the northern hemisphere and in different kind of buildings in comparison to some products by Pilkington Glass UK.

Hybrid aerosol assisted atmospheric pressure Chemical Vapour Deposition: a facile route toward nano-composite thin films?

2009

A hybrid chemical vapour deposition strategy is presented as a facile route for the production of vanadium dioxide nano-composite thin films. The effect of the inclusion of gold nano-particles and the use of a surfactant molecule; tetraoctylammonium bromide (TOAB), is discussed. The films are fully characterised and it is shown that micro-structural changes lead to an enhancement of thermochromic properties, whilst gold nano-particles lead to a change in the films optical properties. Optical data is used in energy modelling studies to elucidate the films potential as an energy saving coating in architectural glazing.
