Abstract

A scheme for designing polycarbonate (PC)/polymethyl methacrylate (PMMA) polymer alternating multilayer optical films with high reflectivity in near-infrared region (780~1100 nm) is proposed. The feasibility for the fabrication of the special multilayer optical films by the micro-nano laminated co-extrusion device is demonstrated. The optimal four-periodic Bragg center wavelength is retrieved by the genetic algorithm, and the optimum film thickness is obtained. The spectral characteristics of four-periodic superimposed multilayer films are simulated and the effects of thickness error and incident angle on the total reflectivity of the multilayer film in the near-infrared region are discussed. The results show that the proposed scheme can meet the requirements of solar heat insulation and intelligent interior lighting.
