A
composite thin film consisting of TiO
2
(binder), uniformly mixed CuFeMnO
4
paint (solar absorber)
was coated on textured aluminum sheets by dip coating. The film’s elemental analysis was done using energy
dispersive x-
ray (EDX) and the surface of the film characterized using scanning electron microscope (SEM). Optical
properties of the TiO
2
/CuFeMnO
4
composite film were also studied using computerized double beam solid-
spec
3700 DUV Shimadzu Spectrophotometer. Reflectance was obtained by spectrophotometric m
easurements, and
thermal emmittance was determined using heat flux
- based technique respectively. Reflectance measurement values
less than 0.03 in the solar wavelength (290 nm < λ < 2500 nm) and low thermal emmittance less than 0.016 for
temperatures betwe
en 24°
C and 100°
C were obtained.
