In this paper, we firstly outline the Chameleon mechanism in the class of theory of modified gravity of f (R), and then apply it in the polynomial – exponential theory of f(R) to find the constraints from the solar system to the parameters α and β of this model. Calculated results show that the chameleon mechanism satisfies easily in the polynomial - exponential theory of f(R), the constraints on the beta and alpha parameters are as follows: 0 <β <0.076; 0 <α <10-46.
