Abstract
Click reactions may be used to bond polymers to lignin by taking advantage of lignin's terminal hydroxyl and thiol groups via an alkyne-azide click reaction or a thiol-alkene or thiol-alkyne click reaction. By selecting functional polymers, these methods may be used to synthesize lignin-containing polymer materials with an array of different properties, such as self-healing polymers.
Claims22
A polymer material comprising:
- a first compound including a first lignin-based core with a first plurality of polymers attached to the first lignin-based core;
- and
