Phase change microcapsules were synthesized using chitosan as the shell material and paraffin as the core material via multi-emulsionization and cross-linking method.During the phase change of the paraffin,the microcapsules can store and release energy.The enthalpy value of the phase change of the microcapsules is higher than 110 J/g.The suitable phase change temperature can be obtained by changing the core material.The resultant microcapsules show excellent thermal stability,and remain stable below 150 ℃ as demonstrated by TGA measurement.The microcapsules also exhibit good solvent-resistance because of the cross-linking between chitosan and glutaraldehyde.
