Variable Electrical Properties in Composites: Application to Vanadium Dioxide Pigments in a Polyethylene Host

Thermochromic Properties of VO2-PVP Composite Coatings

“…This IR modulation is encouraging if one considers the simplicity of the process relatively to the considered references i.e. the results obtained by Valmalette and Gavarri, Alfred-Duplan et al and Gao et al [3,4,5].…”

“…In an effort to produce large efficient and UV radiation stable thermochromic VO 2 based coatings, one should mention the work reported by Valmalette et al and Alfred-Duplan on isobutyl methacrylate-VO 2 and low density polyethylene-VO 2 composite coatings [3,4]. However, their largest reported IR modulations were less than 10% which are smaller to the ones reported in this paper.…”

Phase transition and IR properties of tungsten-doped vanadium dioxide nanopowders

“…Among these oxides, VO 2 has attracted much attention and been extensively studied [1][2][3], because its transition temperature, T t , is close to room temperature (T t < 341 K) [4]. And it can be considered as a very good candidate for a lot of switching applications: thermal sensors, smart IR optical windows [5][6][7], smart IR emissive coatings [8], and switching electrical resistances [9].…”

A Review of Vanadium Dioxide as an Actor of Nanothermochromism: Challenges and Perspectives for Polymer Nanocomposites

“…The first reports on the elaboration of VO 2 -based polymer composites were released in 1994 by Alfred-Duplan, [166] and Valmalette, [116] respectively. Alfred-Duplan et al [166] reported the incorporation of VO 2 particles into low-density polyethylene (LPDE) by melt blending and studied the impact of the thermochromic particles on the electrical properties of the composite material. Complex impedance analyses below and above the insulator-to-metal transition temperature revealed a pronounced influence of the amount of VO 2 on conductivity.…”
