Abstract

Abstract:

Low relative molecular mass gelators have attracted much attention due to their promising properties in oil spill recovery. However, designing a gelator is still challenging. In this paper, a series of organic salts was synthesized. Their structures and gelling properties were characterized by nuclear magnetic resonance spectroscopy(NMR), Fourier transform infrared spectrometer(FTIR), scanning electron microscope(SEM), vial inversion test. The results show that A3C3(A3-cinnamic acid, C3-Laurylamine) can readily gel in crude oil at room temperature. The critical gelation concentration is 6%(mass fraction). A3C3 self-assembles into dendritic three-dimensional entangled network. The formation of gel is due to the synergy between different supramolecular interactions. The increased π-π stacking interactions of the gelator made it easier to gelate. The gelators with phenyl groups are tending to gel in aromatic solvent. This gelling performance will contribute significantly toward the development of the design of organic soft materials.

Key words: low relative molecular mass gelator, oil spill, recovery, supramolecular interaction
