In situ polymerization was proved to be an effective method to prepare composites with combined properties of two intrinsic different components. In this study, poly(decamethylene dodecanoamide) (polyamide 1012, PA1012) powders with controlled morphologies and crystal forms were obtained by antisolvent precipitation, whose morphology and crystal forms were strongly dependent on the types and temperatures of antisolvents. PA1012/polyaniline (PA1012/PANI) composites with different morphologies were manufactured through in situ polymerization. Fourier transform infrared spectroscopy results revealed a strong interaction between PA1012 and PANI components. PANI components were in situ polymerized from aniline monomers on the surface of PA1012 powders, forming a composite aggregates in solution. The conductivity of different PA1012/PANI composite powders was about 10 −5 –10 −3 S/cm, which could successfully meet the requirement of antistatic coating. © 2018 Wiley Periodicals, Inc. J. Appl.
