Abstract
Poly(PyMMP-co-MMA) (PyMMP: 1-pyrenemethyl methacrylate, MMA: methyl methacrylate) was synthesized for using it as a polymer surfactant of poly(vinylidene fluoride) (PVDF)/carbon nanotube (CNT) nanocomposite when the CNT content is high. The surface resistance of the PVDF/CNT composite film was decreased from 0.42 Ω to 0.18 Ω when the carbon content was 40%. The improved dispersion of CNT in the PVDF/CNT/poly(PyMMP-co-MMA) composite film was confirmed from the scanning electron microscopy images of the fractured surfaces. Thus, poly(PyMMP-co-MMA) can be used as a polymer surfactant in the cathode materials of lithium ion batteries.
