Form‐stable phase change materials (PCMs) have great potential to regulate the unbalanced heat demand and supply, yet most of the PCMs are in powder, plate, or bulk rigid forms, difficult to adhere to the heat source or target substrates. Herein, PCMs coatings based on reactive poly(ethylene glycol) (RPEG) are developed for direct thermal energy exchange and storage. RPEG with highly reactive silanol groups is obtained by reaction of PEG with 3‐isocyanatopropyltriethoxysilane (IPTS), followed by hydrolyzation in weak acid. Cross‐linked PCMs coatings are obtained on various substrates, including cotton fabric, wood, tinplate, and even irregular objects. The coatings show obvious solid‐solid phase transition properties and high energy storage densities (142.8 J g−1). Multi‐walled carbon nanotubes (MWCNTs) are further doped into the coatings aided by a self‐cross‐linkable dispersant. The composite coatings exhibit excellent high‐temperature form stability and rapid thermal exchange properties owing to the formation of the cross‐linked network between RPEG and MWCNTs. Thermal regulation clothes are prepared by a spray coating method, which show no performance deterioration after washing three times, indicating good washing durability.

Omega-3 polyunsaturated fatty acids (n-3 PUFAs) enriched eggs are popular for their enrichment of PUFAs, but their freshness and quality are prone to decline with time, particularly if storage conditions are not well maintained. Home storage is the last but a neglected important tach in eggs supply chain, but few studies are available on the egg storage in the home stage. This study aimed to evaluate the internal quality change of both n-3 PUFAs enriched and conventional eggs by simulating eggs stored at consumers' home in refrigeration and under room temperature. The egg quality indices (Haugh unit, yolk index, weight, and albumen pH) were adopted and analyzed for both storage conditions. Wireless sensor network (WSN) was used for real-time monitoring of the temperature and humidity during storage. The results showed that temperature, humidity and time of storage all have an influence on the freshness of both n-3 PUFAs enriched and conventional eggs and there is no significant difference happened to n-3 PUFAs enriched eggs and conventional eggs. Refrigeration can decelerate the quality deterioration of both n-3 PUFAs enriched and conventional eggs and consumers should be educated about how to maintain the internal quality of eggs during home storage.
