Preparation of gradient-structured ultrathin flexible carbon nanotube film and its electromagnetic interference shielding performance
Source abstract
Abstract
From the perspective of ultrathin and flexible electromagnetic interference (EMI) shielding materials, gradient-structured T5/T1/T3 carbon nanotube films (CNTFs) were fabricated via vacuum-assisted layer-by-layer filtration self-assembly, employing carbon nanotubes with distinct aspect ratios. The effects of the structure and pore size of the CNTFs on their electromagnetic shielding performance were systematically investigated using a series of characterization techniques, including scanning electron microscopy (SEM), four-point probe measurement, automated specific surface area and porosity analysis, Raman spectroscopy analyzer and vector network analysis (VNA). Furthermore, the electromagnetic shielding performance of the carbon nanotube films was simulated and verified using COMSOL software.
