제목 Enhanced Sensitivity Colorimetric Detector via Composite of Polydiacetylene and Nanoporous Rice Husk Silica (PDA/NP-SiO2)
초록  Colorimetric detector for identifying the ion concentration with the naked eye was fabricated using Polydiacetylene/nanoporous rice husk silica composites (PDA/NP-SiO2) nanocomposites. It has properties such as the effective, rapid, and easy approach to detect the ion without any kits of analytical instruments at on-site as if pH indicator analysis. NP-SiO2 with a high specific surface area was extracted from rice husk ash via the process of leaching and a sol-gel synthesis and utilized for efficient absorption of the ion. PDA was used as a material to confirm the degree of an ion with the color change by reacting between the functional group in its head site and targeted ion. Consequently, the PDA/NP-SiO2 with the different specific surface areas of silica showed a wide range of color change indicated the degree of ions even at a low concentration.
