Synthesis and Characteristics of Microencapsulated Decanol with TiO2 Shell as Composites for Cold Energy Storage

A novel microencapsulated phase change materials for cold energy storage was synthesised through sol-gel means using decanol as phase change material and titanium dioxide (TiO2) as encapsulated material. The micromorphology and composition of microcapsules were observed by field emission scanning el...
