The article discusses the development of an anisotropic multifunctional thermal insulating hybrid aerogel composed of MXene, reduced graphene oxide, and PEDOT:PSS. This aerogel offers both passive and active thermal protection, capable of regulating heat in extreme environments ranging from 0 °C to 200 °C. It features a stepwise fire warning system that activates color, sound, and light alarms based on temperature changes. The aerogel's design integrates thermal protection and warning capabilities, making it suitable for applications in extreme climates. The research highlights the aerogel's potential in personal thermal management, addressing the challenges posed by global warming and extreme weather conditions.
