ABSTRACT:
A precursor composition adapted for neutron capture induced radiation treatment of said precursor composition including a polymer matrix containing dispersed dopant material, the dispersed dopant material characterized as capable of neutron capture whereupon subsequent in situ energetic ion irradiation of the polymer matrix can occur, and further characterized as dispersed so as to provide dopant domain sizes significantly less than the energetic ion range of the dopant material is provided. Also provided is a process of in situ irradiation of bulk polymeric articles by first providing a precursor composition adapted for neutron capture induced radiation treatment of the precursor composition including a polymer matrix containing dispersed dopant material, the dispersed dopant material characterized as dispersed so as to provide dopant domain sizes significantly less than the energetic ion range of the dopant material, and then exposing the precursor composition to a source of neutrons.
