Lignin nanoparticle synthesis

摘要

A method including reducing a particle size of lignin particles to an average particle size less than 40 nanometers; after reducing the particle size, combining the lignin particles with a polymeric material; and forming a structure of the combination. A method including exposing lignin to a diazonium precursor including a functional group; modifying the lignin by introducing the functional group to the lignin; and combining the modified lignin with a polymeric material to form a composite. An apparatus including a composite of a polymer and lignin wherein the lignin has an average particle size less than 100 micrometers.

1. A method comprising:
mechanically reducing a particle size of lignin particles to an average particle size less than 40 nanometers; after or during mechanically reducing the particle size, exposing lignin particles to a diazonium precursor comprising a functional group, thereby losing N2 from the diazonium precursor and generating a radical form of the precursor, and then reacting the radical form with lignin particles; and after mechanically reducing the particle size, combining the lignin particles with a polymeric material.
