“…Colored surfaces with metallic luster are widely employed in industrial products such as automobiles and household electric appliances because of their luxurious finish. Generally, silver lustrous paints are made by blending aluminum platelets with a polymer, while colored surfaces with a metallic luster are prepared by coating a glossy metal surface with a polymer film containing pigment particles . A representative method for preparing colored reflective films is the preparation of multi‐bilayered films consisting of a highly refractive polymer and less refractive polymer; when the layers have regular intervals, the film exhibits a specific color of reflection due to the interference of light, which is called the structural color.…”

Pd-catalyzed polycondensation of aniline derivatives and 4,4 0 -dibromoazobenzene affords polyaniline analogs containing azobenzene units. The polymers are red in solution and in thin films state, whereas they have a green luster in thick films. Substitution of 4,4 0 -dibromoazobenzene for 4,4 0 -dibromostilbene changes the reflection color from green to blue, whereas the introduction of a non-conjugated unit slightly affects the reflection color. The glossiness of the film is dependent on the smoothness of the film surface. The reflectance measurements using polarized light reveal that reflection spectra correlate well with the complex refractive index (ñ 5 n 1 ik) of the film. These results confirm that the green luster can be attributed to the uniform surface reflection of the object, which has a large refractive index and absorption coefficient at around 500 nm. The polymer films exhibit good transmission of radio frequency signals owing to the lack of free electron carriers.

Electrochemically formed colored passive layers on titanium and their optical, surface morphology, and corrosion properties are presented and discussed. With the application of progressively higher AC voltages (VAC) during preparation of these passive layers, they are found to become more protective of the underlying metal, as determined from corrosion resistance measurements employing electrochemical polarization curve and inductively coupled plasma mass spectrometry experiments. The passive layers on titanium were found to be uniform in their surface morphology with no apparent cracks or pits. Surface morphology, and its relation to optical properties, was also investigated using visible light microscopy, profilometry, and near-infrared ultraviolet visible reflectance spectroscopy measurements. A correlation between the light reflected from the entire sample surface and the coloration of surface grains was also observed through these measurements. The reflectance spectra showed a red-shift of wavelength maxima (λmax) values as AC voltages and, therefore, thicknesses were increased. Overall, these passive layers are protective of an already remarkable metal, and with greater knowledge of the properties of colored protective layers, their potential may be employed in a wide range of applications.

A new facile approach for the fabrication of polymer-Ag honeycomb film is reported. A polymer-Ag + honeycomb thin film is obtained by casting a CHCl 3 solution of a functional graft copolymer on aqueous silver nitrate solution, leading to metal complexation induced phase separation at the air/ water interface. The film is reduced by UV irradiation to give a polymer-Ag honeycomb film with regular morphology. Pyrolysis of the film gives a translucent Ag honeycomb film.
