“Aerogel Cold Chain Storage Box with High-efficiency Thermal Insulation Performance” insulation layer includes phase change materials aerogel phenolic foamed insulation materials,aerogel insulation coatings. The carbon fibre used composite materials as the box shell. It is an innovative vaccine mobile refrigerator that does not require a power supply. It can keep cold for a long timehas good low-temperature stability. Our thermal materials have better cold retentionfire resistance than the insulation material used in the international COVID-19 vaccine storage.

The time-temperature indicator (TTI) developed by immobilizing laccase on electrospun fiber film with high specific surface area. The activation energycoloration of laccase TTI can be adjusted by pHaddition level of laccaseNaN3. This TTI exhibits high accuracy, stability, temperature reversibilitylow cost. The intelligent food packaging developed by this TTI can reduce the food wastethe food safety risk in traditional packaged foods.
