Effect of modified rectorite on interactions of compositions in gel electrolytes

Natural rectorite was modified with dodecyl benzyl dimethyl ammonium chloride, resulting in an organic-modified rectorite (OREC), which was used to modify liquid or gel electrolytes. By conductivity, viscosity and infrared analysis, the interactions existing in organic solvent propylene carbonate (PC), lithium perchlorate (LiClO₄) and OREC used to prepare a gel polymer electrolyte were tested. The results demonstrate that the organic solvent PC has a strong H-bond with the Si-OH on the OREC surface, which can increase the viscosity of the gel polymer electrolyte, and that the conductivity of the composite gel polymer electrolyte increases after adding a certain amount of OREC.
