In
this paper, a series of coated fabrics based on Fe-doped BaSnO3 (BaSn1–x
Fe
x
O3−δ, x =
0.00, 0.05, 0.10, 0.20, 0.25) powder pigments were prepared. The results
indicate that the developed pigments are substitutional solid solutions
with no impurity and the valencies of iron confirmed by X-ray photoelectron
spectroscopy (XPS) are +2 and +3. The BaSn1–x
Fe
x
O3−δ pigments possess high near-infrared (NIR) solar reflectance (64.92–79.81%),
and the change in the near-infrared reflectance value can be explained
by the free carrier concentration and electron trap theory. The pigments
exhibit the alteration of yellow-green to brown, which is ascribed
to the charge-transfer transition (Sn 5s + 5p ↔ Fe 3d). The
BaSn1–x
Fe
x
O3−δ-coated fabrics exhibit excellent high
NIR solar reflectance and thermal insulating performance. The NIR
solar reflectance of the BaSn0.80Fe0.20O3−δ-coated fabric is up to 64.30%. Compared with
those of brown uncoated fabric and conventional brown (Pigment Yellow
42) coated fabric, the inner surface temperature of the BaSn0.80Fe0.20O3−δ-coated fabric is lowered
by 7.6 and 4.2 °C, while the heat absorption is reduced by 51.0
and 37.9%, respectively. The coated fabric shows excellent washing
durability and chemical stability. In summary, these coated fabrics
have the potential to serve as thermal insulation coated fabrics.
