Charge polarization of fission fragments has a significant influence on prompt neutron yield, delayed neutron yield, and nucleosynthesis process (especially r-process). So far, we have introduced the static microscopic theoretical model (Skyrme Hartree-Fock + BCS model) to calculate the charge polarization to construct a method for investigating arbitrary fragmentation. The real-time mean-field (Canonical-basis time-dependent Hartree-Fock-Bogoliubov) calculations have been performed to consider dynamic effects. The pairing functionals used in microscopic theory has not been narrowed down, and its dependence in fission phenomena should be understood for preparing precise theoretical nuclear data. We will investigate the dynamic effects on the charge polarization using several pairing functionals and report the results.
