This study focuses on the properties of carbon nanotube effect on novel calix[8]arene thin film as ion sensing application. The modification of calix[8]arene and carbon nanotube (CNT) were made by both components dissolved completely in chloroform (CH CIଷ ) for 12 hour sonication process, hence cutting off long carbon nanotubes structures and opening their ends [1]. By using spin coating techniques, the thin films were deposited on silicon substrate layer by layer. The morphology and composition of CNT-calix[8]arene have been characterized by Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray (EDX) and Raman Spectroscopy. UVVisible spectrometer also studied in order to understand the behaviour in the molecular level. These supra-molecule material have high potential in the development of sensors to be applied in removing organic and inorganic contaminants from water to safe levels.
