摘要

By incorporating a cationic monomer into the cross-linked polymer framework

we introduced electrostatic interactions that enhance the polymer’s affinity for bilirubin

resulting in outstanding adsorption performance and demonstrating its potential as an effective hemoperfusion adsorbent.

Abstract

Liver is a vital organ in the human body and plays a central role in the metabolism and detoxification of endotoxins and exotoxins. Bilirubin is an endotoxin derived from hemoglobin (Hb). Removing excess bilirubin in the blood is crucial for the treatment of liver diseases. Hemoperfusion

which relies on adsorbents to efficiently adsorb toxins

is a widely applied procedure for the removal of blood toxins. To broaden and improve the range and performance of hemoperfusion adsorbents

we synthesized cationic hyper crosslinked polymers (HCPs) with strong affinity for bilirubin. This material exhibited outstanding adsorption performance

with a maximum adsorption capacity of 934 mg/g and a removal efficiency of 96%. Further investigation confirmed their excellent selectivity

reusability

and biocompatibility. These findings expand the potential applications of HCPs and provide insight into strategies for constructing promising hemoperfusion adsorbent materials.
