Research Progress of Carbon-Based Composite Hydrogels in Adsorption
Carbon-based materials have large specific surface area,well-developed pores,and a large number of oxygen-containing functional groups on the surface,which have excellent mechanical properties.Introducing carbon-based materials into the hydrogel system can increase adsorption sites,improve mechanical properties,enrich network structure,realize complementary advantages,and overcome performance defects,which is the main idea for developing high-performance hydrogel adsorbents.In this paper,the structural characteristics of different types of carbon based composite hydrogels were summarized,and the mechanism of carbon based materials to enhance the performance of hydrogels was emphatically introduced.The preparation methods of composite hydrogels and their applications in the field of water purification were reviewed.The prospects,limitations and future research potential of carbon based composite hydrogels adsorbents were analyzed.
