“…[106] 2) Preparation methods of flexible CNT films. Flexible gas sensors based on CNT film are generally made by coating, [63,107] CVD, PVD, [35] printing, and self-assembly. The coating is the simplest and most understood preparation technique, but it is difficult to control the thickness and uniformity of CNT films.…”

Flexible gas sensors, which can detect gas markers from the human body and hazardous gases from the environment, are attracting tremendous attention recently. Carbon nanotube (CNT) films are explored for flexible gas sensors due to its sensing ability at room temperature, strong adsorption for foreign molecules, mechanical robustness, and remarkable flexibility, and providing nanoscale surfaces with large surface area for various functional materials, etc. In this paper, recent advances in flexible gas sensors based on CNT films are reviewed. It discusses various strategies to design the structure of flexible CNT films and improve flexibility/stretchability performance. It generalizes different types of sensitive materials loaded for detected gases and analyzes the sensing mechanism of CNT films, with interface interactions and synergistic effects leading to an improvement in gas sensing. In addition, it discusses the preparation of CNT self‐standing films and the use of flexible substrates in transformation and assembly, in order to enable CNT films with improved flexible properties. CNT films show remarkable response and flexibility to hazard or greenhouse gases, such as ammonia, nitrogen dioxide, hydrogen, nitric oxide, carbon dioxide, and others. Summary and perspectives toward the future development of flexible gas sensors based on CNT films are proposed.

“…It can quickly conduct heat from one area to another, and it can quickly and evenly distribute the heat during the heating process, so it is a very ideal material for being used in the manufacture of heaters. − However, the process of preparing these materials through the traditional way is complicated with high cost and a long preparation period. In this article, laser-induced graphene (LIG) was prepared on PI films by the laser direct writing technique, , and the prepared LIG exhibited high porosity, excellent electrical and thermoelectric properties, and good mechanical flexibility. ,, At the same time, the preparation is simple, and the preparation cost is low − (Table S1).…”

This paper proposes an LIG-based flexible sensing and heating system for food monitoring (FTMS) for frost protection of food in cold storage. The FTMS integrates two major components: flexible temperature sensing and a flexible laser-induced graphene (LIG) heating patch. Factors affecting the performance of flexible LIG heating patches were investigated from the electrical, thermoelectric, and microscopic levels of the flexible LIG heating patches. The best performance of the prepared flexible LIG heating patches was achieved when the power was 12.5% and the scanning rate was 120 mm/s. In the simulation application phase, through this system, an antifrostbite test is carried out on oranges, pears, and other fruits; when the output voltage is about 3 V, it only takes 14−20 s from the time the fruit meets the cold damage to the time the temperature is pulled back to the set range, and the results show that this system could effectively resist frostbite and monitor the surface temperature of the fruits efficiently. It has a high application value in reducing food waste rates. In the future, we could look forward to its application in rare plant protection and high-value-added crop protection.

“…Their nanometer-scale diameter and micrometer-scale length [ 11 , 12 ] classify them into single-wall carbon nanotubes (SWCNTs), double-wall carbon nanotubes (DWCNTs), and multi-wall carbon nanotubes (MWCNTs). CNTs exhibit excellent optical, thermal, electrical, and mechanical properties, providing extensive prospects in nanocomposite materials [ 13 ], sensors [ 14 ], energy conversion and storage [ 15 ], transparent conductors [ 16 ], flexible electronics [ 17 ], electromagnetic shielding [ 18 ], and catalysts [ 19 ]. However, the strong van der Waals forces among CNTs result in the formation of bundles or larger agglomerates, making it challenging to disperse them in water, organic solvents, or polymer matrices, limiting their applications in various fields [ 20 , 21 ].…”

The inherent π–π interfacial interaction between carbon nanotubes (CNTs) and polystyrene (PS) makes the CNT/PS composite a representative thermoplastic nanocomposite. However, the strong van der Waals force among CNTs poses challenges to achieving effective dispersion. This review provides an overview of various CNT functionalization methods for CNT/PS composites, encompassing covalent grafting with PS-related polymers and non-covalent modification. A focus in this section involves the pre-introduction surface modification of CNTs with PS or PS-related polymers, substantially enhancing both CNT dispersibility and interfacial compatibility within the PS matrix. Furthermore, a comprehensive summary of the mechanical, electrical, thermal, and electromagnetic shielding properties of CNT/PS nanocomposites is provided, offering an overall understanding of this material. The surface modification methods of CNTs reviewed in this paper can be extended to carbon material/aromatic polymer composites, assisting researchers in customizing the optimal surface modification methods for CNTs, maximizing their dispersibility, and fully unleashing the various properties of CNTs/polymer composites. Additionally, high-performance CNTs/PS composites prepared using appropriate CNT modification methods have potential applications in areas such as electronic devices, sensors, and energy storage and conversion.
