Surgical devices inevitably come into contact with blood, bacteria, high temperatures, high humidity, and acidic, basic, and salt environments during use, which can have a significant impact on the device and the operator, so their protection becomes necessary. In this manuscript, novel, highly robust, and superhydrophobic Ni-doped ZnO–ZnS@stearic acid (SA) composite films with extreme repellency to various solid and liquid contaminants, excellent bactericidal performance, and extremely low blood adhesion were fabricated by a simple one-step hydrothermal method. Additionally, the synergistic effect of the in situ generated hierarchical micro/nanocomposite structures on the Zn substrate surface and SA also endowed the film with excellent mechanical and chemical stability, such as ultra-low adhesion, perfect wear resistance, corrosion resistance, heat resistance, and good durability. Notably, the superhydrophobic composite films could be turned into a superhydrophilic film by simple heat treatment. Further, it could revert to its superhydrophobic state by remodification of stearic acid. This unique structure and low surface energy SA modification were found to be the primary reasons for the excellent protection and versatility of galvanized surgical devices in various extreme environments.

“…Typically, the coating techniques can be divided into physical coating methods and chemical coating methods [92]. Physical coating methods include dip-coating [93], spray-coating [94], blade-coating [18], and electrophoretic deposition [95], while chemical coating methods include chemical vapor deposition (CVD) [88], atomic layer deposition (ALD) [96], etc. Similar to the dyeing method of commercial textile processing, dip-coating is a process the outcome of which is the application of a thin film of desired materials to the substrate surface; it can effectively cover textile materials with solution dispersible or soluble functional materials such as carbon nanomaterials [97], conductive polymers [98], and metal nanomaterials [99] in mild conditions.…”

Textile electronics have become an indispensable part of wearable applications because of their large flexibility, light-weight, comfort and electronic functionality upon the merge of textiles and microelectronics. As a result, the fabrication of functional fibrous materials and the integration of textile electronic devices have attracted increasing interest in the wearable electronic community. Challenges are encountered in the development of textile electronics in a way that is electrically reliable and durable, without compromising on the deformability and comfort of a garment, including processing multiple materials with great mismatches in mechanical, thermal, and electrical properties and assembling various structures with the disparity in dimensional scales and surface roughness. Equal challenges lie in high-quality and cost-effective processes facilitated by high-level digital technology enabled design and manufacturing methods. This work reviews the manufacturing of textile-shaped electronics via the processing of functional fibrous materials from the perspective of hierarchical architectures, and discusses the heterogeneous integration of microelectronics into normal textiles upon the fabric circuit board and adapted electrical connections, broadly covering both conventional and advanced textile electronic production processes. We summarize the applications of textile electronics explored so far in sensors, actuators, thermal management, energy fields, and displays. Finally, the main conclusions and outlook are provided while the fabrication and application of textile electronics are emphasized.

“…In addition to the air permeability by utilization of the intrinsic porous fabric structures, the fabric sensor is also designed with the unique waterproof property, which is realized by coating the outside surface of the fabric sensor with hydrophobic STA microsheets to protect the device from invasion of secret sweat and splash water when used in real wearable circumstance. The adhesion of the material to water is a significant evaluation parameter for the application of hydrophobic coating surface, 46 so the water contact angle (CA) between the artificial sweat droplet and the fabric electrode during each fabrication step is probed with optical microscopy (Figure 5d). The pristine nonwoven fabric exhibits an intrinsic strong waterproof property (CA ∼ 126.2°) and becomes hydrophilic after coating with PDA (∼65.2°) and MXene (CA ∼ 74.5°) due to the existence of functional groups, which also confirms the bonding effect of the PDA between the fabric and the MXene.…”

Flexible tactile sensors are under high pursuit for wearable electronics toward healthcare monitoring, human− machine interaction, and artificial intelligence. Permeability and hydrophobicity are emerging unique properties and require significant dedication of research efforts. Herein, we develop a type of flexible, breathable, and waterproof iontronic tactile sensor based on a nonwoven fabric platform using a facile dip-drying and solution-spraying technique. The intrinsic open-ended porous structure of the fabric offers air permeability (∼224.9 mm s −1 ), and the stearic acid microsheets decorated on the outside of the sensor provides effective hydrophobic protection (water contact angle ∼151.9°). The designed electrode-to-electrolyte interfacing microstructures of MXene microspheres and nanosheets on the fabric electrodes and the hierarchical structures with conical secondary features of chrysanthemum pollen on the fabric electrolyte endow the sensor with a high sensitivity of 214.92 kPa −1 and a wide detection range of 0−45 kPa. Fast response time, low detection limit, good dynamic response, and excellent stability are also achieved. With the help of a home-built mechatronic sensing system, the developed fabric tactile sensor can be practically used either as sensor units for human health status monitoring and motion detection or as a sensor array for spatial pressure distribution identification of human−object interaction.
