    • 2 in He at 680°C, at a total flow rate of 580 sccm for 10 min. The catalyst was an iron film, 5 nm thick, that was deposited on a Si wafer substrate by electron beam evaporation. SEM and thermal gravimetric measurements indicated that the purity of the spun yarns was very high (∼96 to 98% C in the form of MWNTs), with 2 to 4% Fe and amorphous carbon. No carbon particles were observed.

    • MWNT/PVA composite yarns were made either by soaking a singles yarn for 15 hours in 5 wt % aqueous PVA solution or by passing a singles yarn through a drop of this solution during spinning, and then drying. The molecular weight of the PVA was in the range 77,000 to 79,000, and it was 99.0 to 99.8% hydrolyzed.
