Surface Modification Efficiency of Titanium-based Particles with an Alkyl Phosphate
Journal Title: NanoWorld Journal - Year 2017, Vol 3, Issue 1
Abstract
This article reports the efficiency of surface modification of titanium particles based on an alkyl phosphate. Different techniques were used to evaluate the behavior of the samples after modification, in terms of better particle dispersion tendency in response to type and quantity of modifier incorporation (TiO2 anatase in crystalline form). The TiO2 nanotubes were synthesized and their surfaces were modified by chemical reaction. Concerning elucidation of the efficiency of anchoring the modifier on the surface of the nanoparticles, the proposed approaches were effective because the treated particles had more active sites. This resulted in efficient disaggregation of the particles, generating lower aggregation and likely smaller particles within the aggregates, by decreasing particle-particle interaction. The use of NMR relaxometry was very useful to probe the chemical modification and also to ascertain the extent of surface modification.
