Novel solid – solid phase change material based on polyethylene glycol and cellulose used for temperature stabilisation

Thermal management is one of crucial issues in the development of modern electronic devices. In the recent years interest in phase change materials (PCMs) as alternative cooling possibility has increased significantly. Preliminary results concerning the research into possibility of the use of solid-solid phase change materials (S-S PCMs) for stabilisation temperature of electronic devices has been presented in the paper. Novel solid-solid phase change material based on polyethylene glycol and cellulose has been synthesized. Attempt to improve its thermal conductivity has been taken. Material has been synthesized for the purpose of stabilisation of temperature of electronic devices.
