Effects of ⁶⁰Co-Irradiation on Gas Permeation Properties of Polyimide Membranes

Abstract:

Radiation effects on polyimide (PI) membranes were studied with different irradiation doses by ⁶⁰Co. The PI membrane were synthesized from 2,2-bis (3-amino-4-hydroxyphenyl) hexafluoropropane (Bis-AP-AF) with 3,3',4,4'-Benzophenone tetracarboxylic dianhydride (BTDA). The single gas permeability of He, H₂, CO₂, O₂, N₂ and CH₄ were measured and compared in order to determine the effect of the the irradiation doses on the gas separation properties. The results showed that the ideal selectivity of He/CH₄, H₂/CH₄, CO₂/CH₄ and H₂/N₂ of the irradiation PI membrane can be significantly improved by irradiation of ⁶⁰Co source. The optimum irradiation doses were 50 kGy. The highest ideal selectivity of He/CH₄, H₂/CH₄, CO₂/CH₄ and H₂/N₂ is 3635.86, 2287.57, 282.00 and 205.29, respectively. In other word, the ideal selectivity of He/CH₄, H₂/CH₄, CO₂/CH₄ and H₂/N₂ of the irradiation PI membrane with 50 kGy irradiation doses is 2.27, 2.11, 1.89 and 1.08 times higher than that of the PI membranes without irradiation.
