摘要：Hexadecane microcapsules with graphene oxide (GO)/poly (urea-formaldehyde) (PUF) hybrid shells were prepared by a simple one-step microencapsulation process in this work. The GO sheets here play dual roles that as an emulsifier and the functional filler. The morphology, shell thickness, and thermal stability of the prepared microcapsules were characterised using scanning electronic microscopy, transmission electron microscopy, and thermal gravimetric analysis, respectively. The results showed that the GO sheets exhibited good emulsifying ability and were successfully introduced into the microcapsule's shell. The hexadecane-loaded microcapsules with GO/PUF shells exhibited excellent thermal and barrier properties.
