This invention relates to the field of new materials, specifically to an organic ionic plastic crystal that facilitates the conduction of anions and cations and its preparation method. The method involves adding different concentrations of anion and cation additives to a tetrafluoroborate-based quaternary ammonium salt plastic crystal, dissolving them in an appropriate amount of acetonitrile, stirring thoroughly, removing the solvent by rotary evaporation, and then vacuum drying to obtain a mixture doped with different concentrations of anions and cations. The tetrafluoroborate-based quaternary ammonium salt plastic crystal obtained by the above method exhibits an ionic conductivity close to practical values ​​after the introduction of anions and cations. The internal conduction of anions and cations can improve the conductivity of the organic ionic plastic crystal, providing a possibility for developing solid electrolytes with high conductivity.

This invention relates to the field of solid-state refrigeration materials with pressure-sensitive effects, and discloses a technical method for improving the adiabatic temperature change decay of plastic crystal materials under constant pressure cycling conditions. The method involves uniformly mixing ammonium iodide plastic crystal grains with silicone oil to form a coating composite system with lubricating and isolating functions. A spherical shell encapsulation structure is then fabricated using PA12 nylon powder via laser sintering 3D printing. The composite system is filled and sealed within the spherical shell to form a stable encapsulation unit. During programmed pressurization and depressurization cycles of the encapsulation unit under constant pressure conditions, the silicone oil effectively reduces inter-grain friction and stress concentration, while the spherical shell structure prevents the loss of the coating medium and maintains the integrity of the system, thereby significantly suppressing the decay of the adiabatic temperature change of the plastic crystal material with increasing cycle count.
