Electrostatic discharge is a fatal threat to a variety of electronic products. Here we report on a polymer nanocomposite composed of a dielectric polymer embedded with aligned core–shell structured nanowires for highly efficient distributed electrostatic discharge protection. The dielectric nanocomposite is capable of self-adaptive charge release, stemming from the nonlinear interface built in the Bi/Co oxide coated ZnO nanowires that leads to a “hand-in-hand” double-Schottky barrier. The ultralow filler concentration (e.g., 0.5 vol %) endows the nanocomposite with low permittivity (close to the pristine polymer matrix) and high optical transmittance (75%) in the visible light wavelength range, which is desirable in packaging materials and display coatings for portable electronics. The effectiveness for electrostatic discharge protection was validated with an organic light-emitting diode screen protected by the nanocomposite that survived multiple rounds of electrostatic discharge.

一种用于自适应电荷释放的介电聚合物/金属氧化物纳米线复合材料

静电放电是对各种电子产品的致命威胁。在这里，我们报告了一种聚合物纳米复合材料，该聚合物纳米复合材料由嵌入对齐的核壳结构纳米线的介电聚合物组成，用于高效的分布式静电放电保护。介电纳米复合材料能够自适应电荷释放，这源于构建在 Bi/Co 氧化物涂层 ZnO 纳米线中的非线性界面，导致“手拉手”双肖特基势垒。超低的填料浓度（例如，0.5 vol%）使纳米复合材料在可见光波长范围内具有低介电常数（接近原始聚合物基体）和高透光率（75%），这在包装材料和显示器涂层中是理想的便携式电子产品。
