摘　　要：针对当前水中持久性、难降解等新兴有机污染物不断出现和积累,亟需发展绿色、低碳、高效的水污染吸附控制技术。常规吸附材料的脱附再生及循环利用是其面临的主要瓶颈问题,继而带来的成本增加及环境压力制约了其进一步发展。热响应型材料(TRM)是一类能够对环境温度变化产生响应进而发生可逆可控相态转变的新型智能材料,目前将TRM用于水处理吸附材料尚罕见报道。基于智能TRM在水污染吸附控制技术中的瞩目前景,对TRM的温敏结构变化机制、TRM对污染物吸附和脱附的作用机理进行了阐释,综述了基于TRM及其复合材料作为吸附剂在水处理中的高效应用,讨论了智能热响应型吸附材料的绿色再生策略,并对围绕TRM的科研方向和实践应用进行展望,以期为生态环境治理过程中减污降碳协同增效提供新的思路。In light of the continuous emergence and accumulation of persistent and refractory emerging organic contaminants in water,it is imperative to develop green,low-carbon,and efficient adsorption technologies for controlling water pollution.The main bottleneck faced by conventional adsorption materials is their desorption-regeneration and cyclic utilization,which increases application costs and environmental pressures,thereby hampering their further development.Thermally responsive materials(TRMs)present a promising solution,as they are intelligent materials capable of undergoing reversible and controllable phase transformations in response to ambient temperature changes.However,there have been limited reports on the use of TRMs as adsorption materials for water treatment.This article aims to address this knowledge gap by exploring the current status of TRMs in intelligent adsorption technologies for water pollution control.We explain the temperature-sensitive structural change mechanisms of TRMs and their effects on pollutant adsorption and desorption.We review the high-efficiency applications of TRMs and their composites as adsorbents in water treatment.Furthermore,we discuss green regeneration strategies of intelligent thermally responsive adsorption materials.We also look forward to future research directions and practical applications of TRMs.This article provides new insights for synergizing pollution reduction and carbon reduction in ecological environmental management.
