Nanocomposite manufacturing using ultrashort-pulsed laser ablation in solvents

and monomers (in English)

Polimery 2008, No 9, 657

Summary

On the basic of literature data on ablation was characterized as a method of nanoparticles preparation. The own research concerned the direct ultrafast laser ablation of solids used to produce the engineering nanoparticles with narrow size distributions. Without using any chemical precursors, stoichiometric nanoparticles are generated from different materials (silver, gold, NiTi alloy) and directly dispersed in a liquid, e.g. acrylic acid, acetone, water, or a monomer of polymeric material. The produced nanoparticle solutions may be used to fabricate nano-modified plastic materials with specially designed properties by polymerization directly subsequent to particles' production, without the necessity to re-disperse the particle aggregates. In order to control the size distribution and related properties, nanomaterial characterization using on-line measurements of the particle size is applied. The developed processes give access to new homogeneous nanomaterials such as multi-component nanosystems.


Key words: laser ablation, nanoparticles, nanocomposites, particle dispersion, femtosecond laser
