In order to promote the in-depth research and practical application of composite phase change thermo-regulated textiles, regarding the current research status of composite phase change temperature regulating textiles, the basic coneept and thermo-regu1ated mechanism of phase change materials were described by literature review and analysis. Then, the research progress of composite phase change thermo-regulated. textiles in photothermal conversion infrared camouflage thermal protection antibacterial thermo chromic and self-healing were reviewed* The problems and challenges in the current research and future development direction of composite phase change thermo-regulated textiles were prospected* The aim is to provide valuable theoretical reference and practical guidance for the further development and application of composite phase change thermoregulation textiles.
