Abstract

To date, numerous strategies have been developed to remove hazardous gaseous components like volatile organic compounds (VOCs) from the airstream. Adsorption technology has been used as an effective approach for the abatement of VOCs for over 30 years. Hyper-cross-linked polymers (HCPs) with permanent porosity, adjustable surface functional groups, and desired physical/chemical properties are recognized to have great potential for the adsorption of VOCs. In this review, the recent research advances achieved in the development of HCPs as adsorbents for the removal of VOCs are discussed with an emphasis on the following aspects: (1) properties of HCPs governing their adsorption performances, (2) removal mechanism of VOCs by HCPs, (3) advantages and shortcomings of HCPs for VOC adsorption, and (4) performance evaluation among HPCs (relative to other adsorption systems). Furthermore, the review was conducted to establish the “property-application” relationships to promote and encourage future research on the formulation of innovative HCP-based adsorptive materials for VOC removal.

摘要

迄今为止，已经开发出多种策略来去除气流中的挥发性有机化合物 (VOC) 等有害气体成分。30 多年来，吸附技术一直被用作减少 VOC 的有效方法。具有永久孔隙率、可调表面官能团和所需物理/化学性质的超交联聚合物 (HCP) 被认为具有吸附 VOC 的巨大潜力。在这篇综述中，讨论了 HCPs 作为吸附剂去除 VOCs 的最新研究进展，重点讨论了以下几个方面：（1）HCPs 的性质决定了它们的吸附性能，（2）VOCs 的去除机理HCPs, (3) HCPs吸附VOC的优缺点, (4) HPC 之间的性能评估（相对于其他吸附系统）。此外，还进行了审查以建立“特性-应用”关系，以促进和鼓励未来对基于 HCP 的创新吸附材料的配方研究，以去除 VOC。
