Herein, a series of foldable buckypaper/polyacrylonitrile (BP/PAN) composite films were developed in a facile strategy. This strategy was based on electrospun and vacuum pressurized filtration methods. The composite film had better mechanical properties than pristine BP via interface reinforcing, but not deprived of excellent conductivity. The maximum tensile strength and elongation at break of BP/PAN films were 1.45 and 11.65 times than pristine BP, respectively. Moreover, BP/PAN film had higher electromagnetic interference (EMI) shielding effectiveness (63.7–65 dB) in the Ku band (12–18 GHz) than pristine BP (34.3–42.9 dB), due to interfaces forming between PAN fibers and CNTs. The BP/PAN composite as a promising EMI shielding material could be utilized in military and civil applications, such as flexible antenna, EMI shielding clothes and soft portable electronic products.

在本文中，以方便的策略开发了一系列可折叠的布基纸/聚丙烯腈（BP / PAN）复合膜。该策略基于静电纺丝和真空加压过滤方法。通过界面增强，该复合膜具有比原始BP更好的机械性能，但并未丧失优异的导电性。BP / PAN薄膜的最大拉伸强度和断裂伸长率分别是原始BP的1.45倍和11.65倍。此外，由于PAN纤维和CNT之间形成界面，因此BP / PAN膜在Ku波段（12–18 GHz）中具有比原始BP（34.3–42.9 dB）更高的电磁干扰（EMI）屏蔽效果（63.7–65 dB）。 。BP / PAN复合材料作为一种有前途的EMI屏蔽材料，可用于军事和民用领域，例如柔性天线，
