基于静电键合的聚醚型聚氨酯基固体电解质柔性封装材料
|
摘要
随着小型功能化移动电子装置的高速发展,制备一种柔性、长寿命的高稳定器件替代传统的刚性电子器件的重要性愈加凸显。静电键合是一种先进的材料连接技术,其连接强度高、密封性好、键合温度低、可以实现异种材料连接等特点在柔性器件的封装中展现出巨大的潜能。传统的聚合物固体电解质室温离子电导率低、机械性能差,无法很好的用于静电键合工艺,同时也制约了静电键合在柔性器件制备与封装中的应用。聚氨酯独特的微相分离结构赋予了其良好的物理化学性能,多样化的载流子通道、可调节的柔性链段以及拥有大量可解离锂盐的极性基团等特点使其成为理想固体电解质基体材料成为可能。从4个方面综述了聚氨酯基体材料进行分子结构设计和制备工艺优化的方法,旨在提高其室温离子电导率和机械性能,适合于静电技术的柔性器件封装。
With the rapid development of small functional mobile electronic devices, the importance of preparing a flexible, long-life, high-stability device to replace traditional rigid electronic devices has become more prominent. Electrostatic bonding is an advanced material joining technology and exhibits enormous potential in the packaging of flexible devices, which has advantages of high connection strength, good sealing, low bonding temperature, and connection of dissimilar materials. The traditional polymer solid electrolyte has low room-temperature ionic conductivity and poor mechanical properties, which cannot be used well in the electrostatic bonding, and also restricts the application of electrostatic bonding in the preparation and packaging of flexible devices. The unique micro-phase separation structure of polyurethane exhibits good physical and chemical properties. The characteristics of diversified carrier channels, designable soft segments, and a large amount of polar groups of dissociating lithium salt make it an ideal solid electrolyte matrix material. In the paper, four aspects of the optimization of the molecular structure and preparation of polyurethane matrix materials were reviewed, aiming at improving the room temperature ionic conductivity and mechanical properties, which was suitable for flexible device packaging with electrostatic bonding.
