CONCLUSION
on the preparation of colloid solutions of silver
nanoparticles from its carboxylates.
It is found that, when using chemical
reduction of silver carboxylates in non-aqueous
Due to the instability of the dispersions media, the dispersion obtained are volatile in
obtained, it was carried out an experiment to obtain organic compounds, aggregating within a short
silver nanoparticles from silver carboxylates in the period. Therefore, it can be concluded, that silver
polymer matrix by reduction of ascorbic acid using nanoparticles from its carboxylates are necessary to
ultrahigh molecular weight polyethylene (UHMWPE) obtain by their stabilization in the polymer matrix.
as a polymer matrix at a temperature of 50°C.
It is preferably to carry out UHMWPE
Ethylene glycol was used as a solvent for impregnation using silver laurate when dissolving
ascorbic acid, and ethanol, methanol and ethylene it in ethyl alcohol, as we obtain the composite with
glycol were used as the solvent for the silver a narrow distribution of nanoparticles with size of
carboxylates. By scanning electron microscopy, evenly distributed on the surface of UHMWPE with
it was revealed that when using ethanol as the a high silver content compared to silver palmitate
solvent, spherical shape particles with diameter not used for this purpose.
exceeding 100 nm (Fig. 3) are evenly distributed on
the surface of UHMWPE, when using methanol, the
larger particles are evenly distributed in UHMWPE
(Fig.4) and a large number of aggregates are
