Abstract:
This work investigates the effects of concentration of organothiol molecules and temperature used during self-assembled monolayers (SAMs) formation on quality of the organothiol SAMs coating layer obtained in terms of wettability, corrosion inhibition efficiency and carbon to copper ratio. The organothiol SAMs were coated on copper substrates prepared by electro-polishing followed by oxygen plasma treatment for 15 s. Three types of organothiol SAMs including 1-octanethiol (OTT), 2-ethylhexanethiol (2-EHT) and 2-phenylethanethiol (2-PET) were investigated. Concentration of organothiol molecules ranging from 0.005 to 0.02 M in isopropanol and forming temperature ranging from -15 to 50 ° C were studied. It was found that all organothiol SAMs of 0.01 M provided the SAMs coating layer with the highest quality. The SAMs formed at 40 ° C with OTT and 2-EHT, and at 0 ° C with 2-PET were the most favorable condition with the highest water contact angle of 124.79 o , 130.66 o and 120.58 o at corrosion inhibition efficiencies of 96.24%, 99.37% and 98.90%, respectively.
