N2 - Defect on the fluid transmission system for example due to fouling or internal surface effect can affect the material quality and impacts the process quality. This work aims at showing a proof-of-concept study to identify defects in the form of line and point defects. The defects were intentionally made at the conductive side of thin conductive oxide glass whilst the thermochromic/PVP composite film was coated on the insulating side. UV-visible absorption spectroscopy was employed to identify the transition temperature of thermochromic as well as thermochromic/PVP composite film. Defects were identified from the spectral changes in the UV-visible absorption spectra. The results reveal that the transition temperature is found at 32.63 ± 1.1°C. Furthermore, line and point defects on the glass surface can be distinguished from the temperature-dependent absorption spectrum measurement.
