The composites formed by copolymer (N-methylpyrrole-co-pyrrole) and Ba0.9Nd0.1Cr0.5Fe11.5O19 ferrite were prepared by in-situ solution polymerization. The phase, morphology, thermal stability, electrical conductivity, electromagnetic properties, and reflection loss of the as-prepared samples were characterized. The results revealed that the Ba0.9Nd0.1Cr0.5Fe11.5O19 ferrite particles have been successfully coated by the (N-methylpyrrole-co-pyrrole) copolymer. The concentration of H3PO4 can make a difference to the conductivities of the as-prepared samples, and affect their microwave absorbing properties. In addition, the composition and thickness of samples also had the remarkable influence on their microwave absorbing properties. What is more, the microwave absorbing properties of the poly(N-methylpyrrole-co-pyrrole)/Ba0.9Nd0.1Cr0.5Fe11.5O19 composites were better than that of single-component counterparts, in which the minimum of reflection loss and the available bandwidth (the frequency width of reflection loss is less than −8 dB) of poly(NMPy-co-Py)/BNCF composite with mNMPy–Py/mBNCF of 5/3 and nNMPy/nPy of 1 at thickness of 2 mm reached to −26.57 dB and 8.36 GHz in the range of 2–18 GHz, respectively. This work suggested that composites could be used as the potential absorbing materials due to their excellent microwave absorbing properties.
