摘要

在这项研究中，我们通过无电解电镀法制备了电磁钴涂层玻璃纤维（Co@GF）复合材料。随后，采用胶带浇注法在室温下成功形成了由 Co@GF 复合材料和液态硅橡胶（RTV-2）组成的导电夹层柔性薄膜。基于 Co@GF 复合材料完美的涂层和优异的导电性能，所制得的 RTV-2/Co@GF/RTV-2 夹层柔性薄膜的体积电阻率低至 0.264 Ω-cm，并且可以拉伸至 100% （4.40 Ω-cm）而无明显断裂。在固化过程中施加磁场时，电磁 Co@GF 复合材料会自动在 RTV-2 基体中排列，这是因为它们具有铁磁性。制备的薄膜在电气性能上表现出各向异性。平行于磁场方向的体积电阻率比垂直于磁场方向的体积电阻率低约两倍。在磁场强度为 800 mT 时，体积电阻率的差异最大（ρ∥ = 0.768 Ω-cm 和 ρ⊥ = 1.549 Ω-cm）。此外，100 mT 的磁场强度有助于提高夹层薄膜的导电性。各向异性的 RTV-2/Co@GF/RTV-2 夹层柔性薄膜被认为是一种很有前途的柔性电子传感器，在这种情况下，需要在正交方向上具有不同的感应灵敏度。

Flexible and anisotropically conductive film by assembly of silicone rubber and cobalt-coated glass fiber composites

In this study, we prepared electromagnetic cobalt-coated glass fiber (Co@GF) composites via an electroless plating method. Subsequently, a conductive sandwich flexible film consisting of Co@GF composites and liquid silicone rubber (RTV-2) was successfully formed using the tape casting method at room temperature. Based on the perfect coating and excellent electrical conductivity of the Co@GF composites, the resultant RTV-2/Co@GF/RTV-2 sandwich flexible film showed a low volume resistivity of 0.264 Ω·cm and could stretch to 100% (of 4.40 Ω·cm) without obvious fracture. When a magnetic field was applied during the curing process, the electromagnetic Co@GF composites were aligned automatically in the RTV-2 matrix because of their ferromagnetic nature. The as-prepared film exhibited anisotropy in its electrical performance. The volume resistivity parallel to the magnetic field direction is approximately two times lower than that in the perpendicular direction. The maximum difference in the volume resistivity (ρ∥ = 0.768 Ω·cm and ρ⊥ = 1.549 Ω·cm) was obtained at a magnetic field intensity of 800 mT. In addition, a magnetic field intensity of 100 mT helps improve the electrical conductivity of the as-obtained sandwich film. The anisotropic RTV-2/Co@GF/RTV-2 sandwich flexible film is considered a promising flexible electronic sensor, where discrepant inductive sensitivity is required in orthogonal directions.
