AB  - In this study, a novel nucleating agent composed of graphene oxide (GO) and 
      silicon dioxide (SiO(2)) (GO-SiO(2)) is developed. GO is used as a skeleton 
      material through which SiO(2) nanomaterials are absorbed and subsequently 
      incorporated into Na(2)SO(4).10H(2)O phase change materials (PCMs). Furthermore, 
      this study examines the phase change performance of the composite 
      Na(2)SO(4).10H(2)O materials. Fourier-transform infrared (FTIR) spectra confirmed 
      the physical combination of GO with a SiO(2) nanoparticles. Scanning electron 
      microscope (SEM) results showed that the GO-SiO(2) composite exhibited a layered 
      structure and excellent dispersibility. The GO-SiO(2) composite 
      Na(2)SO(4).10H(2)O PCMs displayed a low level of supercooling, i.e., about 1.2  degrees C 
      with the addition of GO-SiO(2) at 2.45 wt%. This was because the synergistic 
      relation of the GO and the high dispersion SiO(2), imparted more nucleation sites 
      for Na(2)SO(4).10H(2)O. Additionally, the prepared PCMs achieved high phase 
      change latent heat and thermal conductivity, even under these conditions. The 
      results show that the GO-SiO(2) in the Na(2)SO(4).10H(2)O exhibited advantageous 
      application prospects for the improvement of the thermal performance of hydrate 
      salts.
