A Hierarchically Nanofibrous Self-Cleaning Textile for Efficient Personal Thermal Management in Severe Hot and Cold Environments

“…Meanwhile, the temperatures of the simulated skin covered with the PVB–PDMS side of the HNF textile is 42.9 °C, which is 7.2 and 11.2 °C lower than the one covered with white cotton and bare simulated skin (Figure e, Figure S18b), respectively. Notably, the HNF textile shows superior cooling performance compared to representative textiles reported in the literature (Figure f). ,,,,− This demonstrates that the HNF textile has an excellent cooling capability in high-temperature environments, making it highly possible for effective passive outdoor cooling.…”

“…Obviously, the temperature difference between the PAN-CNT side and black cotton is much greater than that of black cotton/PAN-CNT and black cotton, indicating that the synergistic effect of thermal insulation and radiative heating is better than single radiative heating in low temperature environments. Also, the heating performance of the HNF textile improved significantly, which outperforms the reported radiative heating textiles (Figure e). ,,,,− Additionally, the infrared thermal images of the HNF textile covered on the human arm with the PAN-CNT surface exposed to the outside are displayed in Figure S22. It is clear that surface color of the PAN-CNT side is cooler than that of black cotton, probably because most of the heat cannot be transferred to the upper surface through the HNF textile.…”

“…Liu et al reported a layer-by-layer complex membrane in which silica aerogel is used as a thermal insulation outer layer for temperature control in severe environments. However, a silica aerogel with high infrared emissivity (0.98) could cause a large amount of thermal radiation loss in cold environments, accounting for about 50% of total heat dissipation of the human body. , This research demonstrates that the textiles with radiative thermoregulation need to be combined with aerogel membranes to enhance thermal management performances in high and low temperatures . Therefore, it is necessary to design textiles with improved thermal insulation and radiative thermal regulation to achieve efficient personal thermoregulation in severely hot and cold environments.…”

Wearable Safeguarding Leather Composite with Excellent Sensing, Thermal Management, and Electromagnetic Interference Shielding

“…Then, the electric heating vest was designed based on a leather substrate in Figure 9b, the array design enabled the heat generation area to cover the human body. [41,42] With an LM10 as an array sub-unit, two 2 × 2 LM arrays and one 4 × 4 LM array were designed on the front chest and back of the leather vest, respectively. Then, each LM10 sub-unit was connected by an electrode and wire.…”

Polyaniline/Reduced Graphene Oxide/Carbon Nanotube Composites for Actuation-Based Sensing for Energy Storage

“…Soft actuators are defined as a series of devices that have highly deformable structures or material pieces made with flexible or elastomeric materials, which can convert various forms of external stimulations or input energy (such as chemical energy, light energy, electrical energy, and thermal energy) into desired forces/torques with reversible shape changes, size changes, or property changes. − The actuators can achieve the effects of bending, grasping, lifting, and moving when exposed to external stimuli. They have been widely used in the fields of wearable devices, artificial muscles, soft robots, and so forth. − In recent years, the design of actuators has become more flexible to meet the developments of smart devices. Soft materials such as dielectric elastomers, liquid-crystal elastomers, hydrogels, carbon-based materials, and paper-based materials have been used to fabricate soft actuators. ,,− Among them, carbon-based materials [such as carbon nanotubes (CNTs), graphene and its derivatives, graphdiyne, etc.]…”
