“…Although aerogels can withstand compressive forces in the orders of magnitude greater than their weight, they are also very brittle and they fracture at the slightest shear loading [105,106]. It is made from various types of gels where the fluid is removed, thereby leaving behind only a solid structure.…”

This study evaluated the thermal physiological and psychological responses elicited when wearing cold protective jackets with aerogel fillings in two cold environments, one without air velocities and one with air velocities (2.3 m·s-1), at an air temperature of 10°C. The participants were five healthy young males. Measures were taken of physiological parameters, blood pressure (BP), heart rate (HR), core temperature, oxygen uptake (Vo2), and microclimate (temperature and humidity). The psychological parameters evaluated were thermal and wetness sensation. No differences were observed in systolic blood pressure, heart rate, and oxygen intake between the conditions. At tympanic temperature, a significant difference was observed between the conditions during exercise (p <.05); . A significant difference was observed in the microclimate temperature of the clothing according to the airflow, and temperature changes in the chest and back revealed different patterns. Significant differences were observed in thermal sensation (whole body (p <.05), chest (p <.05), back (p <.01)) between airflow conditions. The results therefore indicate that cold protective jackets with an aerogel filling are suitable for people operating in low-temperature and airflow environments.

This study investigated the application research of aerogel materials in clothing and analyzed the current research focus on aerogel clothing, the details of the development of aerogel materials, and the evaluation of the application effects of aerogel in clothing. Current research mainly focuses on the application of aerogel in firefighting clothing, space suits, wetsuits, and footwear products. The aerogel materials used in surveyed studies can be classified into aerogel fiber composite, aerogel foam composite, and aerogel coating fabric. Aerogel fiber composite is the most widely used aerogel material in the clothing industry. The thermal performance, mechanical properties, and comfort performance of aerogel clothing have been qualitatively discussed. This survey revealed that aerogel positively affects thermal performance of clothing. In addition, the mechanical properties such as the durability and strength of aerogel materials can meet the application requirements of clothing. However, the dust contamination hazard of aerogel particles limits the further application of aerogels in clothing. In addition, the experimental evaluation of the comfort performance of aerogel clothing through human- and manikin-wearing experiments is insufficient. The findings of this study reveal that it is essential to conduct further studies on the comfort performance of aerogel clothing to determine whether aerogel can have widespread application in clothing. Lastly, we provide suggestions on directions for future studies on the application of aerogels in clothing.
