Abstract

In this study, we demonstrated that well-defined poly(glycidyl methacrylate)-grafted non-woven polypropylene (PP-g-PGMA) can be reproducibly achieved by pre-irradiation at the current-adjusted higher dose rate, and further used as an efficient heavy metal adsorbent by functionalization using ethylenediamine (EDA). The results of grafting degree and conversion rate revealed that the desired degree of reproducible grafting of PP-g-PGMA (while maintaining the conversion rate above 90%) can be achieved under the optimized conditions. The successful synthesis of PP-g-PGMA was clearly confirmed using Fourier transform infrared spectrometer spectroscopy (FTIR), thermogravimetric analysis (TGA), and field emission scanning electron microscopy (FE-SEM). The PP-g-PGMA-EDA adsorbents produced by the amine reaction exhibited grafting degree-dependent amine density ranging from 2.8 to 3.5 mmol/g. It also had good tensile properties suitable for application to metal ion adsorption. Noticeably, the PP-g-PGMA-EDA adsorbent exhibited better Cu2+ ion-adsorbing performance than did the commercial resin.


본 연구에서는 전류로 조정된 높은 선량율에서의 전자선 전조사 및 접목중합 반응을 통해 poly(glycidyl methacrylate) 접목 polypropylene 부직포(PP-g-PGMA)를 높은 재현성으로 제조하고 이를 ethylenediamine(EDA)을 이용한 기능화를 통해 효율적인 중금속 흡착제로 적용해 보고자 하였다. 접목중합 수율 및 전환율 평가 결과, PP-g-PGMA의 제조에 있어 최적조건에서 90% 이상의 높은 전환율을 유지함으로써 높은 재현성을 보이며 원하는 접목수율을 얻을 수 있었다. Fourier transform infrared spectrometer spectroscopy(FTIR), thermogravimetric analysis(TGA) 및 field emission scanning electron microscopy(FE-SEM) 분석을 통해 PP-g-PGMA가 성공적으로 합성되었음을 명확히 확인하였다. 아민 반응에 의해 제조된 PP-g-PGMA-EDA 흡착제는 접목중합 수율에 의존적인 2.8에서 3.5 mmol/g 범위의 아민 밀도를 나타내었고 금속이온 흡착제에 적용하기에 적합한 인장특성을 나타내었다. 특히, 제조된 PP-g-PGMA-EDA 흡착제는 상용 수지보다 더욱 우수한 Cu2+ 이온 흡착 성능을 보였다.
