Abstract: There are provided thermoregulatory coatings for paper comprising a nano structured phase change material (PCM) and a protective layer, the PCM including a first agent that undergoes an endothermic phase transition at a desired temperature and a second agent that assists in maintaining a nano structure, and the protective layer providing a basecoat, a top-coat, or both. There are also provided coated papers and articles comprising such coatings, and methods for preparation thereof. Coated papers and articles provided herein have a wide range of application, for example in packaging or transport of temperature-sensitive materials.
