\begin{document}$S U(3) $\end{document} quark mean field model (PCQMF). Nonextensivity is introduced within the PCQMF model through a dimensionless parameter q to examine the viscous properties, such as shear viscosity (η) and bulk viscosity (\begin{document}$\zeta_b$\end{document}), and conductive properties, such as electrical conductivity (\begin{document}$\sigma_{el}$\end{document}) and thermal conductivity (κ). Additionally, some key thermodynamic quantities relevant to the transport coefficients, such as the speed of sound (\begin{document}$c_{sq}^2$\end{document}) and specific heat at constant volume (\begin{document}$c_{vq}$\end{document}), are calculated. The temperature dependence of the transport coefficients is explored through a kinetic theory approach with the relaxation time approximation. The results are compared to those of the extensive case where q approaches 1. The nonextensive q parameter is found to have a significant effect on all transport coefficients. We find that the nonextensive behaviour of the medium enhances specific shear viscosity \begin{document}$\eta/s_q$\end{document}, as well as conductive coefficients \begin{document}$\sigma_{el}/{\rm T}$\end{document} and \begin{document}$\kappa/{\rm T}^2$\end{document}. In contrast, the normalized bulk viscosity \begin{document}$\zeta_b/s_q$\end{document} is found to decrease as the nonextensivity of the medium increases. We also studied the transport coefficients for finite values of chemical potentials. The magnitudes of η, \begin{document}$\sigma_{el}$\end{document}, and κ increase at lower temperatures, while ζb is found to decrease for systems with non-zero chemical potential."> Impact of nonextensivity on the transport coefficients of strongly interacting QCD matter -
