Extended Data Fig. 1: Hansen solubility parameters (HSPs) of the thermoelectric polymers (a, N1 and b, N2) and elastomers.
HSP consists of three parameters representing different interactions, including δd for dispersion (van der Waals interactions), δp for polarity (dipole moment interactions), and δh for hydrogen bonding. The solubility distance (Ra) between the conjugated polymer and elastomer is determined by the formula: (Ra)2 = 4(δd2-δd1)2 + (δp2-δp1)2 + (δh2-δh1)2. Lower Ra implies better miscibility between two materials. The HSPs and Ra of the thermoelectric polymers and elastomers are summarized in Supplementary Table 2.
