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.

研究了无染料比色法检测挥发性有机化合物（VOCs）的传感材料的制备.结构色的变化将通过改变颗粒尺寸和同时改变颗粒排列的周期性来表现。为此，在单分散球形二氧化硅颗粒上均匀沉积可溶胀的层状硅酸盐。通过仅在二氧化硅颗粒的表面上的选择性侵蚀来实现沉积，以得到硅酸盐阴离子作为层状硅酸盐的来源之一。阳离子表面活性剂被插入层状硅酸盐的层间空间，导致粒径的增加。具有周期性排列的疏水性溶胀性球形颗粒对VOC的吸附会产生结构色响应。
