Assembly of citrate gold nanoparticles on hydrophilic monolayers

Abstract

The self-assembled layers were all hydrophilic with Lipa-pTHMMAA exhibiting close to full wetting. AFM reveals that the polyacrylamide layers smoothens the gold surface to a higher extent than the polyethylene glycol and lipoic acid terminated with an amino group. SPR resonance curves were observed to shift to higher angles and become increasingly damped, while also the peaks strongly broaden when large nanoparticles assembled on the surface. Topographical images confirmed that the highest number of particles were assembled on the polyethylene glycol monolayer. By increasing the interaction time more particles could be assembled on the surface.

Inhibition Effect of Three-Dimensional (3D) Nanostructures on the Corrosion Resistance of 1-Dodecanethiol Self-Assembled Monolayer on Copper in NaCl Solution

“…Self-assembly has been recognized as a prospective technology for creating functional materials, owing to the extended and two-dimensional molecule layers that can provide excellent corrosion resistance and surface superhydrophobicity [ 6 , 7 , 8 ]. When compared with the traditional corrosion inhibition methods, SAMs exhibit the advantages of high coverage, few defects, and high inhibition efficiency [ 9 , 10 ]. Yamamoto et al [ 11 ] reported that copper with alkanethiol self-assembled layers obtained excellent anticorrosion abilities.…”
