Multifunctional phase change gel coating with solar thermal conversion, UV detection and antibacterial property

With the increasing popularity of wearable devices, developing multifunctional wearable devices using phase change materials for personal thermal management is of great significance for improving personal comfort. In this work, multifunctional phase change gel coating with solar thermal conversion, UV detection and antibacterial property is proposed. Biomass myristic acid is confined by the cross-linking network of styrene ethylene butylene styrene to fabricate the phase change material gels (PCMGs) with thermal storage capacity. Solar absorbing Te in PCMG can efficiently realize solar-thermal convertion. UV-responsive photochromic capsules in PCMG can detect UV intensity in the environment. Silver nanorods in PCMG have excellent antibacterial properties to provide additional security. Combining these advantages, multifunctional phase change gel coatings prepared by screen printing possess excellent wearable performances.
