MOF가 도입된 PEI 기반 다공성 복합체의 CO2 흡착 성능 및 모폴로지 분석

초록

In this study, a porous composite was designed by dispersing a metal–organic framework (MOF) into a polyetherimide (PEI) polymer support to enhance the efficiency of the CO2 capture process. Morphological analyses using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) confirmed a uniform porous structure with well-dispersed MOF particles on the composite surface. Mechanical testing revealed a maximum tensile strength of 7.00 MPa, and thermogravimetric analysis showed less than 10% weight loss up to approximately 400 °C, indicating the material’s suitability for high-temperature gas-related applications. Furthermore, CO2 adsorption measurements using the Brunauer–Emmett–Teller (BET) method demonstrated an adsorption capacity of 0.85 mmol g–1, confirming its potential as an effective CO2 composite. Therefore, the PEI–MOF based the porous composite developed in this work exhibits excellent potential for efficient CO2 capture.
