The rapid proliferation of electronic devices has heightened the demand for efficient electromagnetic interference (EMI) shielding materials, as conventional alternatives increasingly fall short in mitigating harmful electromagnetic radiation. In this study, we report the fabrication of acrylonitrile butadiene styrene (ABS) nanocomposite films reinforced with graphene nanoplatelets (GNPs), offering a promising solution to this growing challenge. A persistent issue in incorporating GNPs into the ABS matrix is their poor wettability, which impedes uniform dispersion. To overcome this, a sonication-assisted casting technique was employed, enabling effective integration of GNPs at loadings of 1, 3, and 5 wt%. The resulting nanocomposite films exhibit uniform dispersion and enhanced functional properties. Comprehensive characterization using FESEM, UV-Vis spectroscopy, TGA, DSC, FTIR, and dielectric/EMI analyses revealed significant improvements in thermal stability, UV absorption, and dielectric behavior. Notably, the films demonstrated moderate EMI shielding effectiveness, reaching 0.0064 dB at 4 MHz. These findings position the developed GNP-reinforced ABS nanocomposites as promising candidates for advanced applications in the automotive, aerospace, and electronics industries.
电子设备的迅速普及增加了对高效电磁干扰（EMI）屏蔽材料的需求，因为传统替代品在减轻有害电磁辐射方面越来越难以满足要求。在本研究中，我们报告了用石墨烯纳米片（GNPs）增强的丙烯腈-丁二烯-苯乙烯（ABS）纳米复合薄膜的制备，为这一日益严峻的挑战提供了一个有前景的解决方案。将GNPs掺入ABS基体中的一个长期存在的问题是其润湿性差，这阻碍了均匀分散。为克服这一问题，采用了超声辅助浇铸技术，能够在1 wt%、3 wt%和5 wt%的负载量下有效整合GNPs。所得纳米复合薄膜表现出均匀分散和增强的功能特性。使用场发射扫描电子显微镜（FESEM）、紫外-可见光谱、热重分析（TGA）、差示扫描量热法（DSC）、傅里叶变换红外光谱（FTIR）以及介电/电磁干扰分析进行的全面表征显示，在热稳定性、紫外线吸收和介电行为方面有显著改善。值得注意的是，这些薄膜表现出适度的电磁干扰屏蔽效能，在4 MHz时达到0.0064 dB。这些发现使所开发的GNPs增强的ABS纳米复合材料成为汽车、航空航天和电子行业先进应用的有前景的候选材料。
