Microencapsulated phase change materials with graphene nanoplates (GNPs) embedded polyurea shell and n-docosane (C-22) as core material were fabricated via Pickering emulsion polymerization. GNPs was used in combination with regenerated nanochitin as Pickering emulsifiers for enhanced stability due to mutual hydrophobic and electrostatic interactions. The microcapsules with 10 wt% GNPs (GNPs10/PU@C-22) exhibited melting enthalpy as high as 185.5 J/g and thermal conductivity as high as 0.65 W/m.K. GNPs10/PU@C-22 was also used to prepare composite films that showed great potential in thermal management of mobile phone devices.
