Abstract:	Block copolymer thin films fabricated from polystyrene-polyferrocenylsilane (PS-b-PFS) block copolymers on silicon substrates were used as precursors of well-ordered, nanosized growth catalysts for carbon nanotubes (CNTs). The size of the catalytic domains was tuned by changing the mol. wt. of the block copolymer, enabling control of the diam. of the CNTs grown from these substrates. CNT growth on catalytic substrates with larger organometallic domain sizes, using acetylene as a carbon source, resulted in enhanced amts. of CNT deposition compared to smaller PFS domains, which exhibited low catalytic activity. The inner and outer diams. of the multi-walled CNTs obtained were typically 8 and 16 nm, resp., and were not influenced by the catalytic domain sizes. Various annealing strategies in inert or in hydrogen atm. were studied. The use acetylene with an addnl. hydrogen flow as gas feed resulted in a significant increase in deposition on all PS-b-PFS decorated substrates. Under these conditions, the CNT diams. could be controlled by the catalyst domain sizes, resulting in decreasing diams. with decreasing domain sizes. Multiwalled CNTs with inner and outer diams. of 4 and 7 nm, resp., and a narrow diam. distribution were obtained.
