We study 2d Floquet conformal field theory, where the external periodic driving is described
by iterated logistic or tent maps. These maps are known to be typical examples of dynamical
systems exhibiting the order-chaos transition, and we show that, as a result of such driving,
the entanglement entropy scaling develops fractal features when the corresponding dynamical
system approaches the chaotic regime. For the driving set by the logistic map, fractal
contribution to the scaling dominates, making entanglement entropy a highly oscillating function
of the subsystem size.
