| Summary: | Water is a necessity in our everyday lives. Due to the limited amount of consumable water,
water treatment technologies such as filtration systems has been on the rise. With this system
we are able to process water into usable water. This technology poses a major challenge which
is membrane fouling which in turn causes more issues like replacement of the filtration
membranes. Electroanalytical methods such as electrochemical impedance spectroscopy (EIS)
has been researched to help with detection of such fouling. However, delamination issues have
been noticed on electrodes used for EIS when placed in corrosive and high crossflow
environmental conditions. This research is to test for ink compositions and surface treatment
conditions for fabricating the most optimal adhesion strength electrode for EIS. It was found
that adhesion strength of film to substrate was mainly attributed to surface treatment done on
the substrate though ink composition does play a factor in improving adhesion properties as
well. This finding is believed to provide valuable insights into developing electrode with better
adhesion for the application of EIS. |
