AB  - Fast thermal response and sensitivity of organic latent heat storage materials 
      with inherent low thermal conductivity to external temperatures is still a 
      challenge in their practical applications. Herein, a shape-stable heat storage 
      material composite, composed of interconnected netlike graphene, hexadecane, and 
      commonly used high-density polyethylene (HDPE), was obtained using a convenient 
      melt blending method. The start melting temperature, melting temperature, and end 
      melting temperature of the obtained shape-stabilized thermal storage materials 
      are presented, indicating that the response rate of the composites to ambient 
      temperature could be indeed increased. This is because the interconnected netlike 
      graphene with high conductivity intercalated into the HDPE matrix provided many 
      conductive pathways for heat transfer. Therefore, the thermal conductivity of the 
      composites is increased to 0.67 W/(m.K), which is about 123% higher than that of 
      pure hexadecane. Meanwhile, the structure of polyethylene and hexadecane is 
      similar, and hexadecane is uniformly dispersed in polyethylene and perfectly 
      combined with polyethylene, which can effectively prevent the leakage of 
      hexadecane during the phase transition. Thus, the obtained composites may play an 
      important role in thermal management applications such as heat collection, 
      transportation, thermal power conversion, and so forth.
