Lignin as a Fortifier for the Synthesis of Cellulose Composite Aerogel with Strong Mechanical Performance

摘要

The cellulose composite aerogels that were both high porosity and strong mechanical performance would have promising implications for bioengineering field; however, creating this aerogels had a challenge to choose compatible fortifier. Here we reported lignin as a reinforcement element to synthesis the cellulose composite aerogels with strong mechanical performance. Our approach - straightforwardly dissolved in ionic liquids and simply regenerated in the deionized water - causes assembly of micro-and nanoscale and even molecule level of cellulose and lignin. The resulting aerogels exhibited a strong mechanical performance. The successful synthesis of this aerogels developed a path for lignin to an advanced utilization.
