a Polymer chain structures. b Phonon dispersion relations. The q is the wavevector, the \(\omega\) is phonon frequency and the average phonon group velocity of one branch is estimated as the slope of the origin to the maximum frequency point as shown in the red dashed line in the PHTC001 structure.
