The approach is demonstrated by uniformly coating organic polymer encapsulated PCMs with zinc oxide, which allows thermal percolation through the interconnected inorganic shells. We demonstrate that hydrogen peroxide sol-gel processing can be used to form such uniform zinc peroxide coatings which are then converted by chemical treatment to zinc oxide shells. The way to overcome different challenges associated with the synthesis of thin film coatings of organic PCMs by zinc oxide are addressed, and the favorable attributes of the new doubly coated PCM capsules are demonstrated.||URI:||https://hdl.handle.net/10356/144418||ISSN:||2196-7350||DOI:||10.1002/admi.201900368||Rights:||This is the accepted version of the following article: Mikhaylov, A.
