摘要

为了解

-取代对聚苯并咪唑(PBI)水/盐传输行为的影响，考虑PBI中咪唑环上的N‍―‍H键较为活泼，选择3种具有可对比性的

-取代基团(对联苯甲酰基、对联苯磺酰基、丁烷基)与PBI中N‍―‍H基团反应，用核磁、傅里叶红外光谱、X-射线衍射、示差扫描量热和表面电势考察了

-取代后PBI的物化性质，并以溶解-扩散理论为基础，研究不同

-取代基团对PBI聚合物膜的水/盐传输行为的影响. 研究结果表明，

-取代改性使聚合物链之间的相互作用降低，聚合物分子链间距增大，同时膜表面电负性增强. 同时，与PBI相比，

-取代改性使得PBI分子链间产生更大的自由体积空穴，增加了水的传输通道，并提高亲水基团的可及性而降低自由水的含量，从而能够有效提高PBI膜的水/盐溶解、扩散和渗透选择性. 其中，对联苯磺酰基其扩散水渗透系数与PBI相比提高了30倍，表现出最优异的水/盐传输性质. 为了解聚合物改性对PBI水/盐传输性质的影响，也为未来面向脱盐高性能聚合物的分子结构设计提供了参考.

Abstract

In order to understand the effects of

-substitution on the water/salt transport behavior of polybenzimidazole (PBI)

in this work

considering that the N―H bond on the imidazole ring in PBI is reactive

three comparable

-substituted groups (

-benzoyl

-benzenesulfonyl

and butyl) were selected to react with the N―H group

and the physical and chemical properties of PBI after

-substitution were investigated by nuclear magnetic resonance (NMR)

Fourier transform infrared spectroscopy (FTIR)

X-ray diffraction (XRD)

differential scanning calorimetry (DSC) and surface zeta potential

and solution-diffusion theory to investigate the effects of different

-substituted groups on the water/salt transport behavior of PBI. The results show that the

-substitution modification leads to the reduction of interactions between polymer chains and the increase of polymer molecular chain spacing

while the electronegativity of the membrane surface is enhanced. At the same time

the

-substitution modification results in larger free volume cavities between PBI molecular chains

which increase the water transport channels

and increases the accessibility of hydrophilic groups and decreases the content of free water; thus

it can improve the water/salt solubility

diffusivity and permeability selectivity of PBI effectively. Among them

-biphenylsulfonyl whose diffusive water permeability coefficient is 30 times higher compared with PBI

exhibits the most excellent water/salt transport properties. It provides an understanding of the effect of polymer modification on the water/salt transport properties of PBI

and also provides a reference for future molecular structure design of high performance polymers oriented to desalination.
