The clothes play the greatest role in protecting the human body, but under some extreme conditions, the warmth brought by the clothes cannot prevent cold invasion, so that the multifunctional protective clothes are urgently needed to be developed, and the more efficient heating and heat preservation of the human body are realized. Meanwhile, a large amount of waste clothes garbage is generated in the world every year, the waste clothes generate a large amount of waste and environmental pollution to cause energy waste, and how to utilize the waste clothes as resources is of great significance for achieving the strategic goal of carbon neutralization.
Heating the human body to maintain a relatively constant temperature is critical to various human body functions. However, most of the existing heating strategies consume energy and waste energy, and cannot cope with complicated and variable environments.

The obtained textile can be heated up under illumination, can utilize the passive radiation of a human body, and has the capability of accurately heating the human body. (ACS Nano 2021, 7, 11396-11405) Zhou et al developed a novel multifunctional textile composite material by assembling Kevlar fiber, shear hardening gel (SSG) and two-dimensional MXene, which has high-sensitivity monitoring characteristics on various stimuli from slight physiological activities to impact of a human body, and can realize thermal management of the human body and complete heating and heat preservation of the human body under the power-on condition.
