US Patent 8143337 - Preparing composite with disperse long fibers and nanoparticles


This patent from Ohio State University teaches combining the advantages of fiber-reinforced and nanoparticle-doped polymers while improving nanoparticle dispersion. Claim 1 reads:

1. A method of preparing a composite material including nanoparticles and fibers dispersed in a resin, comprising the steps of:

binding nanoparticles to said fibers;

adding said fibers having said bound nanoparticles thereon to said resin; and

unbinding said nanoparticles from said fibers so as to disperse said nanoparticles in said resin.
