Abstract: Nanocrystalline diamond wires and layers were grown by microwave plasma CVD technique on Si substrates. The substrates were pretreated by non-woven composite nanofiber textile composed by poly(vinyl alcohol) matrix and ultra-dispersed diamond (UDD) nanoparticles prepared by needleless electrospinning method. High concentration of UDD in the PVA fibers lead to formation of diamond wires due to a combined effect of UDD particles used as seeding and high pressure difference across the fibers interface. A preferable growth of diamond layers was observed on areas with a low porosity volume of nanofiber textile. The influence of spundond structure on the growth of diamond decreased with lowering of UDD concentra-tion in the primary polymer matrix.
