“…formation using alcohol-terminated alkanethiols and modifying the monolayer with an alkyltrichlorosilane to form a 2-dimensional polymer monolayer [5,[39][40][41]. Similarly, we performed in previous work a molecular bilayer as well as mixed monolayers on copper with great protection efficiency for the bilayer system [27,[42][43][44][45].…”

“…4a) and Cu-DT (Fig. 4b) was deconvoluted into three components, attributing to the functional groups of -CH 3 , -CH 2 -and HS-CH 2 with blinding energy of 286.6, 284.7 and 285.4 eV, respectively [22]. Besides, the intension ratio between the -CH 3 (or HS-CH 2 ) and -CH 2 -components in Cu-OT and Cu-DT was obviously different.…”

In this paper, we tried to fabricate a compact and thick mercapto functional silica sol-gel coating to achieve excellent corrosion resistance performance on copper. A detailed comparative study of alkylthiol self-assembled monolayers (SAMs) and mercapto functional silica sol-gel coating prepared by 1-octanethiol, n-dodecanethiol and (3-mercaptopropyl)trimethoxysilane (MPTMS) was carried out. The elements composition and chemical bonding of the protective coatings were characterized by X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. In addition, the cross section morphologies of Cu-MPTMS sol-gel coating were investigated by field emission scanning electron microscopy. The wettability of various coatings was investigated by contact angle measurement instrument. Finally, the anti-corrosion ability of the coatings was characterized using an electrochemical workstation. Results demonstrated that compared to other alkylthiol SAMs, the Cu-MPTMS sol-gel coating showed the best anti-corrosion property in sodium chloride solution because it owned a multiple hierarchic Si-O-Si network structure, thus to achieve a higher range of thickness and lengthen the diffusion path way of corrosive medium. It was also found that compact and thick mercapto functional silica sol-gel coating shows better corrosion resistance performance than other SAMs of the same type.

“…However, outstanding results were obtained with silanes containing sulphur or mercapto groups, such as bis-[triethoxy-silylpropyl]tetrasulfide [24], 3-mercapto-propyl-triethoxy-silane [25]or 3-mercapto-propyl-trimethoxysilane (PropS-SH) [26][27][28][29][30][31][32][33][34].…”

Atmospheric corrosion of fire-gilded bronze: corrosion and corrosion protection during accelerated ageing tests

Fire-gilded bronze (replicating the materials of Lorenzo Ghiberti’s Paradise Door (Baptistery of Florence, 1452)) was aged in runoff/stagnant conditions by accelerated exposure tests in synthetic acid rain. After preliminary electrochemical investigations, a detailed characterization of gilded bronze samples before and after artificial ageing tests followed. Surface and cross-sections analyses were performed by FIB/FEG-SEM, SEM/EDS and micro-Raman spectroscopy. The protective efficiency of a coating based on 3-mercapto-propyl-trimethoxy-silane was also quantitatively assessed by GF-AAS through analysis of metal release, while the aesthetical appearance of coated and uncoated gilded bronze before and after ageing was evaluated by colour measurements
