摘要
本文以聚丙烯腈(PAN)纤维为基体,通过预辐照接枝改性在纤维表面引入胺基制备得一种固态胺纤维(PAN-AF).通过反射红外、热重分析、单丝拉伸等手段表征了纤维改性前后相应基团的变化、表面化学结构和热稳定性等性能.评价了所得纤维对CO2的吸附再生性能.结果表明,该纤维可以完全除去混合气中的CO2;吸附CO2后,纤维在100°C中加热30min即可完全再生,经过四次循环吸附再生后,其吸附性能仍维持原纤维的吸附性能.
A novel solid amine fiber was prepared through pre-irradiation grafting amino compound onto the PAN fiber precursor. Physical and chemical properties of the amine fiber were characterized by Fourier-transform infrared spectroscopy,thermo gravimetric analysis and monofilament tensile. The amine fiber showed excellent adsorption performance for CO2,it could thoroughly removal CO2 from the mixed air. The regeneration properties of the amine fiber after CO2 adsorption were also studied. The results showed that the amine fiber could be regenerated by heating at 100 ℃ for 30 min. The fiber exhibited similar CO2 adsorption property to the fresh fiber after four regeneration cycles.
