| 要約: | Many high-end industries including the marine, oil and gas, and biomedical industries
are severely affected by metal corrosion and the presence of microbial activity further
accelerates the corrosion process. The smart functional coating materials with
synergistic anticorrosion and antifouling properties are currently developed as new
steel protection strategy. Therefore, this study aims to evaluate the anticorrosive and
hygienic properties of a new coating formulation comprising an epoxy matrix and
PEDOT:PSS-Ce doped ZnO hybrid composite (HC) as the functional agent for the
protection of stainless steel (SS 316L) and mild steel substrates. The effects of HC
compositions on anticorrosion and hygienic properties of epoxy coatings were
investigated by varying the HC compositions at 1, 3 and 5 wt%. The HC coatings were
characterised using Fourier Transform Infrared Spectroscopy (FTIR), X-Ray
Diffraction (XRD) and Scanning Electron Microscope (SEM) with Energy Dispersive
X-Ray Spectroscopy (EDX) analyses. The Ce doped ZnO was synthesised through the
citrate gelation method and solid state sintering and characterised using ATR-FTIR,
XRD, SEM/FESEM and EDX. The photocatalytic efficiency of Ce doped ZnO was
evaluated in a series of photodegradation test under UV light using methylene blue
dye as the indicator. |
