Method & Evidence

AimHow can cellulose-assisted graphene dispersion in microencapsulated phase change materials improve the thermal conductivity and thermal regulation capabilities of textiles?

MethodMaterials science and experimental testing

ProcedureGraphene nanosheets (GNs) were dispersed using cellulose nanofibers (CNFs) to create thermally conductive microencapsulated phase change materials (MPCMs-GNs). The morphology, structure, and thermal properties (melting enthalpy, thermal stability, thermal conductivity) of the MPCMs-GNs were characterized using techniques like SEM, FTIR, XRD, DSC, TG, and thermal conductivity testing. Mechanical properties were assessed via nano-indentation. Finally, the performance of MPCMs-GNs integrated into textiles was evaluated for thermal regulation.
