US Patent 7862766 - Electron beam functionalization of nanoscale fibers

Functionalization of nanotube films is used to strengthen the films but can be time consuming using conventional techniques. This patent from Florida State University Research Foundation teaches a more rapid approach using electron beam irradiation. Claim 1 reads:

1. A method of functionalizing a nanoscale fiber film material, comprising the steps of:

(a) providing a nanoscale fiber film material which comprises a plurality of nanoscale fibers; and

(b) irradiating the nanoscale fiber film material with a controlled amount of radiation, wherein the step of irradiating the nanoscale fiber film material comprises applying an electron beam to the nanoscale fiber film,

wherein the electron beam applies a dose of electrons in the range from about 10 ×1015 to about 300×1015 e/cm2.
