Abstract

Absorption and scattering are important parameters that reflect the radiation performance of porous materials but cannot be directly measured. By solving the radiation transfer equation by Monte Carlo method, the relationship between the material's absorptivity, scattering, reflectivity and transmittance can be established. Then, when the reflectivity and transmittance have been measured, the absorptivity and scattering can be obtained by genetic algorithm inversion. The absorptivity and scattering of cellulose acetate porous membrane samples were obtained by the above method, which proved the feasibility of the method.
