Understand the good conductivity of composite bubble films

Silicate nanocomposite bubble membranes can also be used as polymer electrolytes. For polyethylene oxide electrolyte, its conductivity is much lower than the melting point temperature. This decrease is due to the formation of crystals at 20, which prevents particle movement, while intercalation can prevent crystal growth, thereby improving the conductivity of the electrolyte.

Due to the immobility of silicate layers in nanocomposite bubble film plastics, the conductivity of nanocomposite bubble film plastics is single particle conductivity. From the planar particle conductivity curve of lithium montmorillonite nanoplastics, it can be seen that the conductivity of the electrolyte decreases by an order of magnitude at the melting temperature. On the contrary, within the same temperature range, temperature has little effect on the conductivity of nanocomposite bubble film plastics: the conductivity only slightly decreases with the decrease of temperature. This composite bubble film can be used to package electrical products and prevent static electricity.

In addition, the surface activation energy of nanoplastics is similar to that of molten polymer electrolytes. This indicates that the activity in nanoplastics is essentially the same as that in a large amount of melted electrolyte. In addition, the conductivity of melt intercalated nanoplastics is higher than that of solution intercalated nanoplastics, indicating significant anisotropy. This may be due to the presence of excess polymer in the melt intercalation material, which provides an easy conductive path.
