Abstract
This disclosure provides methods for grinding biochar composition for use as a filler in elastomeric compositions. Such methods include providing a biochar composition comprising particulate, and grinding the biochar composition with a grinding fluid until the biochar is characterized as having an average particulate size less than substantially 1 micrometer. Optionally, such methods may include passivating the biochar composition during or after grinding by covering a sufficient portion of the surface pores sized 10 nanometer and smaller of the particulate forming the ground biochar composition. Curable elastomeric compositions including biochar and cured elastomeric products are also provided.
