Considering the importance of friction coefficient in bearing performance and the good properties of MoS2, this paper designs an innovative friction sliding isolation bearing with MoS2 as the lubricating material. The relationship between the friction coefficient and the compressive stress was determined by fitting the results of a loading test, and the feasibility of the material was proved through a shaking table test on a five-layer concrete frame model. Based on the energy dissipation theory, the seismic behavior of the proposed friction sliding isolation structure was simulated on MATLAB/Simulink. The simulation results show that the entire structure had little displacement, despite the slight slippage of the isolation layer, under the simulated earthquake wave. The energy response at different friction coefficients shows that the total seismic energy input of the system increased with the friction coefficient. The change of the total seismic input was not obvious when the friction was up to 0.15. The research findings shed new light on the application of isolation devices in practical engineering
