| Research Abstract |
Fabrication of colorimetric sensing materials for volatile organic compounds (VOCs) without dyes has been investigated. Change in a structural color will exhibit by varying particle size and simultaneous changing the periodicity of the particle arrangement. For this purpose, a swellable layered silicate on monodispersed spherical silica particles was deposited homogeneously. The deposition was achieved by selective erosion only on the surface of the silica particles to give silicate anion as one of the sources of the layered silicate. A cationic surfactant was intercalated into the interlayer space of the layered silicate, leading to the increase in the particle size. Response of a structural color will occur to VOC adsorption on the hydrophobic swellable spherical particles with periodic arrangement.
