AB - Waterborne polyurethane (WPU) has been intensively utilized as host materials for intrinsic conducting polymers. However, the stability and compatibility between polyaniline (PANI) and WPU remain a challenge for their composites. In this research, anionic–nonionic sulfonated waterborne polyurethane (SWPU) is adopted as matrix to prepare nanosized PANI‐g‐SWPU dispersions through chemical graft polymerization method, and the stability mechanism is systematically investigated. The PANI‐g‐SWPU dispersion is endowed with much higher stability and no PANI precipitation is detected after storage for 1 year when the PEG molecular weight is 1000 and R value is 1.2. The surface resistivity reaches the minimum when the graft time is 2.5 h, pH value is 2, n(APS)/n(aniline) is 1, and the aniline content is 20 wt %. And the resistivity of the coated paper reaches 1.39 Ω cm, indicating that the as‐prepared PANI‐g‐SWPU dispersion can be directly used as the antistatic coatings, which is also suitable for large scalable production. © 2017 Wiley Periodicals, Inc.
