Design and durability study of environmental-friendly room-temperature processable icephobic coatings was written by Wu, Xinghua;Zhao, Xin;Ho, Jeffrey Weng Chye;Chen, Zhong. And the article was included in Chemical Engineering Journal (Amsterdam, Netherlands) in 2019.Name: Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate This article mentions the following:
Ice accumulation leads to improper functioning or even damages to ships, offshore platforms, sports facilities and land buildings in cold climate regions. Although fluorochems. have demonstrated attractive performance for icephobic applications, their use has been restricted due to health and environmental concerns. Here, we present a facile method to fabricate fluorine-free icephobic coatings with potential applications for outdoor facilities and structures. The coating consists of a silicone-epoxy hybrid resin, polydimethylsiloxane (PDMS) and SiO2 nanoparticles with different sizes. Particularly, the use of different sized (10-20 nm and 200 nm) SiO2 nanoparticles results in excellent icephobicity and mech. properties. The mech. properties and durability of the coating were analyzed according to resp. test standards and compared with other reported icephobic coatings. The durable icephobic potency of the coatings is very promising as a sustainable green solution for various practical anti-icing applications. In the experiment, the researchers used many compounds, for example, Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate (cas: 41556-26-7Name: Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate).
Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate (cas: 41556-26-7) belongs to piperidine derivatives. The piperidine ring can be found not only in more than half of the currently known structures of alkaloids, but also in many natural or synthetic compounds with interesting biological activities. Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol.Name: Bis(1,2,2,6,6-pentamethylpiperidin-4-yl) decanedioate
