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 degrees 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.
