Fund Project: This study was supported by the National Natural Science Foundation of China (No. 51275332) (No. 51275332)the Natural Science Foundation for Young Scientists of Shanxi Province, China (No. 2014021025-2). (No. 2014021025-2)

In this study, powders of polyethylene oxide (PEO) and lithiumperchlorate (LiClO₄) were used as the raw materials for producing the ionic conduction polymer PEO-LiClO₄ with different complex-ratios and used for anodic bonding through high energy ball milling method, and meanwhile, X-ray diffraction, differential scanning calorimetry (DSC), ultraviolet absorption spectrum test analysis, and other relevant methods were adopted to research the complexation mechanism of PEO and LiClO₄ and the impact of the ionic conduction polymer with different complex-ratios on the anodic bonding process under the action of the strong static electric field. The research results showed that the crystallization of PEO could be effectively obstructed with increased addition of LiClO₄, thus increasing the content of PEO-LiClO₄ in amorphous area and continuously improving the complexation degree and the room-temperature conductivity thereof, and that the higher room-temperature conductivity enabled PEO-LiClO₄ to better bond with metallic aluminum and have better bonding quality. As the new encapsulatingmaterial, such research results will promote the application of new polymer functional materials in micro-electromechanical system (MEMS) components.
