聚乙烯亚胺(PEI)功能化策略及其在二氧化碳捕集中的研究进展与展望
Functionalization Strategy of Polyethyleneimine (PEI) and Its Research Progress and Prospect in Carbon Dioxide Capture and Concentration
摘要: 近年来，聚乙烯亚胺(PEI)凭借丰富的胺基活性位点、低成本优势以及高效的化学吸附性能，已成为固态胺基CO2捕集材料领域的研究热点。然而，其实际应用仍受制于胺基失活、氧化降解、浸出流失及再生能耗高等关键瓶颈。本文系统梳理了近年来PEI功能化改性的主要策略，涵盖物理负载与复合、共价接枝、化学结构修饰及绿色合成途径，并在此基础上，对该领域未来的发展方向进行了前瞻性展望。
Abstract: In recent years, polyethylenimine (PEI) has become a research hotspot in the field of solid amine-based CO2 capture materials, owing to its abundant amine active sites, low cost, and high chemisorption efficiency. However, its practical application remains constrained by key bottlenecks, including amine deactivation, oxidative degradation, leaching loss, and high regeneration energy consumption. This review systematically summarizes the major strategies for PEI functionalization developed in recent years, covering physical loading and compositing, covalent grafting, chemical structure modification, and green synthesis routes. On this basis, it also provides a forwardlooking perspective on the future development directions in this field.
