Enhanced dispersion of graphene sheets in various liquid solvents supported by poly(ionic liquid) via non-covalent interaction
In this study, a new method for the preparation of graphene using poly(ionic liquid) [PEP-MIM]Cl was found and the complex [PEP-MIM]Cl-GO, which combines with graphene oxide (GO) via electrostatic and π-π interactions, was investigated to be dissolved in the organic or aqueous phase, depending on the concentration of the poly(ionic liquid), and to be stably dispersed and liquid crystalline. After reduction to graphene (rGO) by L(+)-ascorbic acid, this stable dispersion can still exist without any agglomerates, and thus the poly(ionic liquid)- functionalised graphene [PEP-MIM]Cl-rGO with good dispersibility in water was prepared, and some explorations of phase transfer and anion exchange of [PEP-MIM]Cl-rGO based on the ion exchangeability of the poly(ionic liquid) were made. exchange, and the success of the preparation of poly(ionic liquid)-functionalized graphene was confirmed by TEM, AFM, FTIR, Raman and other characterizations.
期刊介绍：
The journal includes papers in the following areas:
– Simple organic liquids and mixtures
– Ionic liquids
– Surfactant solutions (including micelles and vesicles) and liquid interfaces
– Colloidal solutions and nanoparticles
– Thermotropic and lyotropic liquid crystals
– Ferrofluids
– Water, aqueous solutions and other hydrogen-bonded liquids
– Lubricants, polymer solutions and melts
– Molten metals and salts
– Phase transitions and critical phenomena in liquids and confined fluids
– Self assembly in complex liquids.– Biomolecules in solution
The emphasis is on the molecular (or microscopic) understanding of particular liquids or liquid systems, especially concerning structure, dynamics and intermolecular forces. The experimental techniques used may include:
– Conventional spectroscopy (mid-IR and far-IR, Raman, NMR, etc.)
– Non-linear optics and time resolved spectroscopy (psec, fsec, asec, ISRS, etc.)
– Light scattering (Rayleigh, Brillouin, PCS, etc.)
– Dielectric relaxation
– X-ray and neutron scattering and diffraction.
Experimental studies, computer simulations (MD or MC) and analytical theory will be considered for publication; papers just reporting experimental results that do not contribute to the understanding of the fundamentals of molecular and ionic liquids will not be accepted. Only papers of a non-routine nature and advancing the field will be considered for publication.
