Novel nanocontainer to store corrosion inhibitors
Researchers have proposed a novel electrochemically assisted deposition technique (EAT) to construct graphene-based nanocontainers to store corrosion inhibitors.
EAT enables graphene (Gr, rather than graphene oxide, GO) to be used to fabricate composite nanocontainers. Silica films deposited on graphene nanosheets by EAT have high coverage, strong adherence and can be up to 60 nm thick. The resulting Gr/SiO2 nanocontainers were further modified by dodecyltrimethoxysilane (DTMS) to prepare superhydrophobic nanocontainers.
Excellent protective properties
The high-barrier graphene and hydrophobically modified SiO2 in Gr/SiO2/DTMS nanocontainers could synergistically resist corrosive mediums. The polyvinyl butyral coatings doped with Gr/SiO2/DTMS nanocontainers pre-loaded with inhibitors exhibited excellent protective properties.
The study has been published in Progress in Organic Coatings, Volume 178, May 2023.
