The self-healing eutectogels with multifunctionality have attracted much attention in soft materials owing to their high conductivity and non-volatility. However, obtaining eutectogels with complete recovery of mech. properties is still challenging. Herein, we developed a series of halogenated dibenzylidene-D-sorbitol (X-DBS) gelators. The X-DBS could form eutectogels in deep eutectic solvents obtained from choline chloride combined with alcs. or urea, which exhibit self-healing, complete recovery, load-bearing, and injectability. Fourier transform IR, 19F NMR, and mol. dynamics simulations showed that the hydrogen bond between the C-F bond and the solvent mol. is key to the self-healing property of the eutectogels. Interestingly, the high ionic conductivity and self-healing property of our eutectogel make it potentially useful in a smart ionic conductor. Moreover, the self-healing eutectogels with corrosion resistance showed good lubricating performances on steel interfaces. In addition, the eutectogels showed excellent dye adsorption, effectively removing dyes from aqueous solutions Thus, the efficient DBS-based eutectogels with self-healing properties are excellent candidates for conductive materials, interfacial lubrication, dye adsorption, and other applications. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6Safety of 1,2-Propanediol).
1,2-Propanediol (cas: 57-55-6) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Safety of 1,2-Propanediol
