Preparation of Chitosan/polyvinyl Alcohol Composite Aerogels Regulated by Tannic Acid and Their Photothermal Evaporation Properties
摘要
Abstract
Using chitosan,polyvinyl alcohol,tannic acid,and Fe3+solution as raw materials,a suspen-sion was obtained through hydrogen bonding,and then a three-dimensional interconnected porous structure of chitosan/polyvinyl alcohol/tannic acid composite aerogel was achieved by freeze-drying.Thanks to the complex formed between tannic acid and Fe3+ions in the material,this aerogel demon-strated an evaporation rate of up to 2.36 kg·m-2·h-1 and an evaporation efficiency of 74.9％in pure water environments.The synergistic cross-linking effect formed by hydrogen bonds between chi-tosan,polyvinyl alcohol,and tannic acid effectively enhanced the structural stability of the aerogel;ad-ditionally,the aerogel's high salt resistance further ensured its excellent seawater desalination per-formance even after continuous evaporation.关键词
