This study investigated the reflection spectra of wrinkled metal/polymer multilayers. A wavy surface was self-assembled by annealing an aluminum-coated poly(methyl metacrylate) layer on a silicon substrate. The total and diffuse reflectance characteristics of the sample with additional metal coatings(aluminum or silver) were evaluated in the visible wavelength(400~800 nm) using a spectrophotometer. The results showed that the wrinkled surface enhanced the diffuse reflectance up to 40~50% in the lower-wavelength range, demonstrating its potential for applications to optical thin-film devices.
