“…For example, Pei et al took 8 hours to disperse 60 wt% CNT in the chitosan (CS) by ball milling to prepare CNT/CS composites with porous network structures. The CNT/CS composites showed an EMI SE of 25.07 dB [19]. Although ameliorating the dispersion can help to prepare a composite with high loading fillers, the EMI shielding effectiveness of the composite is hard to further improve by such a simple mixing method.…”

3D printing is a rapidly developing field because it has been widely used in the rapid design and manufacturing of flexible sensors to meet the needs of complex soft structures and devices. In this study, a composite hydrogel ink composed of polyvinyl alcohol, silk fibroin, conductive polymer, and carbon nanotubes is designed,and using 3D printing technology an “artificial epidermis” with long‐term environment stability and self‐healing ability is created. In addition, the “artificial epidermis” also has the multifunctional characteristics of sensing pressure, strain, temperature, and humidity. It has a wide pressure (0–165 kPa), strain (0–355%), temperature (−20–68 °C) and humidity (45–85%) sensing range and high sensitivity. While detecting the tiny movements of the human body, after self‐healing, the device can fully restore its sensing capabilities and perform accurate human monitoring. Furthermore, it can also monitor changes in temperature and humidity, distinguish between hot and cold water, and perform detection of water droplets. Customized 3D printing of flexible electronic devices has opened up new ways for the biological integration of various sensors in wearable electronic systems and the application of advanced bionic skin.

“…With the possibilities offered by today’s technology, only a limited number of processes can be performed with the experimental analysis method used in the analysis of CNTs. Examples of these processes are the CNT stress test and electromagnetic shielding analysis [ 38 , 39 ]. It is not possible to perform more complex analysis, such as wave propagation analysis using the experimental analysis method.…”

In this study, behaviors of electromagnetic wave propagation in a double-walled carbon nanotube (DWCNT) are investigated theoretically. For this purpose, the effects of carbon nanotube’s inner and outer tubes’ material property parameters (μ, ε) on electromagnetic wave propagation are discussed. The effects of interaction between the carbon nanotube’s inner and outer tubes on the electromagnetic wave propagation are defined. Nonlocal effects of the DWCNT on electromagnetic wave propagation are examined. Besides, the electromagnetic wave propagation frequencies are specifically investigated, taking the DWCNT’s nonlocal effects and material property parameters (ε, µ) into account. When the wavenumber, k, is greater than 1.8 × 1010, the frequencies of the fundamental mode and the second mode converge to 3.554 × 108 Hz. Additionally, the electromagnetic wave propagation frequencies decrease with the increase of the DWCNT’s nonlocal parameter (ν) and decrease with material parameter (D).
