Estimation of Interphase Affinity of Doped Polyaniline Nanorods to Localizein Hard Domains of TPU/PANI-ES Blend

In this study, the low levels of the synthesized HCl-doped polyaniline (PANI-ES) nanorods (lowerthan ۲ wt%) were blended successfully with the synthesized MDI/BDO/PTMG-based TPU bysolution method. Compatibility and miscibility between PANI-ES chains and hard segments (HS) inthe blends were theoretically verified based on solubility parameters and interfacial tension. Thedependences of the degree of microphase separation (DPS) on PANI-ES content was quantified withspectroscopy. The obtained results indicated that the PANI-ES nanorods were localized in TPU harddomains and confirmed their synergistic role in forming centralized intermolecular hydrogenbondinginteractions
