Abstract
The present invention provides methods to functionalize and solubilize WCNT with a phenolic polymer such as a lignin or a PF resin followed by in-situ integration of this functionalized CNT in the presence of formaldehyde and phenol and/or lignin to generate either CNT-reinforced phenol-formaldehyde polymer or CNT-reinforced lignin-phenol-formaldehyde polymer in either liquid or powder form suitable as an adhesive in the manufacture of a lignocellulosic composite material such as OSB and plywood.
