Web24 Mar 2024 · Recent observation of second sound in graphite at a temperature above 100 K has aroused a great interest in the study of thermal waves in non-metallic solid materials. … WebThe graphene acoustic absorber was integrated by self-standing ultrathin graphene drums and PF frame by the hydroplastic foaming method. Figure 16b shows that the absorption coefficient of PFGA was much higher than that of the PF, in both the high and low frequency range. The sound-absorption ability of PFGA continuously increased with GO content.

Second sound is a quantum mechanical phenomenon in which heat transfer occurs by wave-like motion, rather than by the more usual mechanism of diffusion. Its presence leads to a very high thermal conductivity. It is known as "second sound" because the wave motion of entropy and temperature is similar to the propagation of pressure waves in air (sound).
