Abstract
The effect of the method of nanodiamonds oxidation (with acids or with air oxygen) on the amount of oxygen-containing functional groups on the particles surface and stability of the aqueous dispersions has been studied. Composite polymer films based on polyvinyl alcohol and nanodiamonds batches have been prepared; the effect of the oxidation procedure on the film structure, elasticity modulus, and tensile strength has been elucidated. The most stable aqueous dispersions (containing the smallest particles) as well as the most uniform and strong composite films (exhibiting the highest elasticity modulus and tensile strength) have been obtained using the ShA-A nanodiamonds batch (Sinta, Belarus) oxidized with air oxygen.
