Abstract

High-density glass-like carbon has numerous applications in the aerospace, electronic, medical implant and automotive industries. Much effort has been devoted to limiting the number of impregnation cycles necessary for the preparation of carbon in this form, and now it has been shown that organometallic methods permit a two-step (oligomerization and functionalization) entry into thermoset precursors for high-density glass-like carbon.
