“…The highest visible transmittance was nearly 48%, which is considerably lower than that of the VO 2 -polymer coating [103]; this lower transmittance can be originated from different film thickness and volume fraction of VO 2 particles. Most promising result were observed by Chen and coworkers [106], who employed highly dispersed VO 2 nanoparticles in polyurethane (PU) host after surface adjustment by polyvinylpyrrolidone (PVP).…”

“…Three studies examined the effect of composite host on the MST properties of VO 2 films. One of which reported that submicronic VO 2 -polymer coating had a proper transmittance with average of 65% in the visible region and ΔT IR of about 25% [103]. As shown in Fig.…”

“…Size and volume fraction of VO 2 particles are important factors in determining the optical properties of the composite coating [104]. This apparent relation was justified by multiple scattering effect of the embedded particles [103]. The VO 2 -polymer coatings exhibited an increasing trend in value of ΔT sol from 3.8% to 11.6% as the volume fraction of VO 2 altered from 0.3 to 3.0.…”

“…The VO 2 -polymer coatings exhibited an increasing trend in value of ΔT sol from 3.8% to 11.6% as the volume fraction of VO 2 altered from 0.3 to 3.0. However, the spectral transmittance in the visible region decreased largely due to the diffuse scattering effect caused by submicronic size of particles [103].…”

VO 2 has been intensively studied as a model system for Metal-Insulator Transition, ever since its phase switching behavior at relatively low temperature (T c =68°C) was discovered. Its thermo-active characteristics have been studied for applications in thermal solar collectors to prevent overheating of the fluid absorber, smart windows and smart tiles to optimize thermal comfort in buildings. In the last decades, strong efforts were made to develop protocols to process VO 2 -based material into thin films, coatings, porous layers and glazings in order to provide thermo-active properties to common substrates. A selection of complementary works in both the synthesis of VO 2 nanoparticles and formulation of VO 2 -polymer nanocomposites is proposed in the present review. The perspective of this work is to provide an easy entry to the thermochromic nanocomposite research field as a tutorial to tackle future challenges such as improving the application-oriented properties, in particular transition temperature T c and solar transmittance modulation ΔT sol . Synthesis techniques to fabricate VO 2 particles and nanoparticles and strategies to insert VO 2 particles in a polymer matrix are presented.

Due to the growing need for smart windows for buildings to reduce energy usage, vanadium dioxide (VO2) has been investigated as a potential material for thermochromic smart windows due to its ease of implementation and simplicity in industrial production. VO2 undergoes a reversible phase shift from a monoclinic (M, P21/c) semiconductor to a rutile (R, P42/mnm) metal at a critical temperature of 68 °C. This transition is accompanied by acute variations in IR reflectance, transmittance, and electrical resistance. Despite substantial developments in thermochromic materials, their optical and transition properties are still unsatisfactory. In the past several decades, many methods for enhancing optical properties have been reported, including composite films, multilayer structures, and element doping. Recent developments in thermochromic smart windows to improve both optical properties and durability have been surveyed in this review. Additionally, future growth trends have been provided by the possibility of commercially manufacturing VO2 smart windows.This article is protected by copyright. All rights reserved.
