Abstract:
This research has concerned the preparation and characterizations of polycarbonate
(PC)/tungsten oxide (WO3) composite films exhibiting photochromic properties for building
applications. The composite films were prepared by solvent casting method, using various
contents of WO3 ranged from 1-8 % (w/w). Microstructure of the composite films were
evaluated by scanning electron microscope (SEM). Optical and chromic properties of the
products were determined using UV-visible spectroscope and colorimeter, respectively. In
addition, mechanical properties were examined by texture analyzer. From the results, it was
found that the color of composite films changed from bright to dark color upon an exposure
to UV radiation. It was also found that the color changing process is reversible. However, the
forward and backward color changing rates were different. In terms of the optical properties,
it was found that the presence of WO3 strongly affects percentage solar absorption (%SA),
whereas the effects on light transmission (%LT) and solar reflection (%SR) were less
remarkable. Results from SEM also revealed that WO3 and PC are phase separated. WO3 with
particle size ranged from 1 to 15 μm was obtained, depending on WO3 particles dissolved in
PC solution. Moreover the presence of WO3 resulted in an increase of modulus and tensile
strength of PC, with the maximum value of tensile strength at 2 wt% of WO3 content
