Diamond growth on copper rods from polymer composite nanofibres

Popis výsledku v původním jazyce

The potential uses of diamond films can be found in a diverse range of industrial applications. However, deposition of diamond films onto some foreign materials is not a simple task. Here we present the growth of adherent diamond films on Cu rods with the focus on substrate pre-treatment by PVA composite nanofibres. The primary role of the PVA fibres substantially act as a carbon source which enhances the diamond nucleation and accelerates a homogenous CVD growth. Diamond growth was carried out in linear antenna MWCVD system at various gas compositions. Combination of PVA polymer fibres use together with this unique deposition system leads to a successful overcoating of the copper rods by continuous diamond film without the film cracking or delamination. We propose that the sequence of plasma-chemical reactions enhances the transformation of certain number of carbon atoms into the sp3-bonded form which further are stabilized by atomic hydrogen coming from plasma.
