The thermal conductivity
of pure PDMS at 27 C is about 0.19Wm1 K1, while that of
GS/PDMS and GF/PDMS composites is 0.46Wm1 K1 and
0.56Wm1 K1, i.e. 2.42 and 2.95 times that of pure PDMS, respectively.
Yu et al. [26] reported that the thermal conductivity of
0.7 wt.% GS/PVDF composite was about 0.45Wm1 K1, very close
to our result of GS/PDMS composite.
