Abstract:
In this study, polymeric ionic liquid (PIL) was synthesized and used in the wet spinning of calcium alginate (CaAlg) fiber. PIL was used as an intermediate to coat graphene with outer layer of CaAlg fiber to obtain conductive core-sheath CaAlg/Graphene (CaAlg/G-PIL) fibers. This proposed blend enhances the properties of the fiber due to the π-π and cation-π interactions between PIL and graphene, and the electrostatic interactions between PIL and CaAlg. The composition and chemical structure of the composite fibers were characterized by infrared spectroscopy, Raman spectroscopy, scanning electron microscopy and thermogravimetric analysis. The properties and applications of the composite fibers were characterized by tensile test and a series of electrical conductivity tests. The results show that the modification of PIL realizes non-covalent combination of CaAlg fiber with graphene, improving the electrical conductivity of the fiber.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
02:42Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

00:42Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
