Abstract:
Homogeneous core‐shell systems were obtained with a growth, in controlled steps, of several oligoamides on TiO 2 nanoparticles. Derivatives of natural compounds, such as l ‐tartaric acid and α,α′‐trehalose, were used as diesters in the polycondensation reactions with ethylenediamine. TiO 2 anatase was chosen because of its high photo‐activity and its antimicrobial activity. The TiO 2 nanoparticles had been previously activated then functionalized using two different coupling agents, and finally, the TiO 2 ‐oligoamide nanocomposites were synthesized using two synthetic pathways. The final products were characterized by 1 H NMR, 13 C NMR, FT‐IR, and transmission electron microscope. These nanocomposites can show improved properties in comparison with the single components (TiO 2 nanoparticles or oligoamides), which are useful in many fields, such as antimicrobial coatings for surfaces in cultural heritage conservation. A nanocomposite (TiO 2 ‐polyethylenetartaramide) was used for applicative studies, and it has shown a good efficacy against fungal attack by Trametes versicolor on wood specimens ( Fagus sylvatica ). © 2015 Wiley Periodicals, Inc.
