摘要：A polystyrene-poly(methyl methacrylate)(PS-PMMA) hydrophobic layer was constructed on the surface of 13X molecular sieve and PS-PMMA/13X molecular sieve was prepared via a biomimetic lotus-leaf-like structural design. By integrating an organic nanoscale surface architecture, the fabrication of PS-PMMA/13X molecular sieve was achieved under mild conditions without disrupting the crystalline framework of the 13X molecular sieve, while maintaining thermal stability up to 370 degrees C. The water contact angle increased to 127.6 degrees , indicating significantly enhanced hydrophobicity. The modified 13X molecular sieve exhibited excellent water resistance while preserving its intrinsic adsorption properties. Static adsorption results revealed that CO2 adsorption on PS-PMMA(0.05)/13X follows the Langmuir model and is dominated by physisorption. After 6 h of water immersion followed by drying, the material retained over 92% of its adsorption capacity after ten cycles. Furthermore, under simulated humid flue gas conditions [15% relative humity(RH) and 15%(volume fraction) CO2], the CO2 adsorption capacity reached 0.045 g/g, representing a 73% increase compared to pristine 13X molecular sieve, effectively suppressing competitive adsorption from water vapor. The PS-PMMA(0.05)/13X molecular sieve demonstrates excellent CO2 adsorption performance under high temperature, low concentration, and humid conditions. With a simple preparation method and robust performance, it shows strong potential for practical carbon capture applications.
