Research Progress of Phase Change Materials for Thermal Management in Electronic Components

Advanced Materials Interfaces, EarlyView.
Phase change materials(PCMs) can effectively solve the overheating problem in electronic devices during use, but the low themal conductivity of PCM itself hinders its development. The problem of low thermal conductivity can be addressed by using metal fins, adding nanparticles and porous metal foams.
