Nanocomposite manufacturing using ultrashort-pulsed laser ablation in solvents and monomers

Abstract

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.

Metal‐Polymer Nanocomposites for Functional Applications

“…It can be done both under vacuum conditions [29,66] and in solution. [67] In the vacuum process, laser ablation from a metallic target and a polymeric target has been combined. Therefore it shows some similarity to a co-sputter deposition process.…”

Dose‐dependent surface endothelialization and biocompatibility of polyurethane noble metal nanocomposites

“…The recently introduced technique of pulsed laser ablation in liquid (PLAL) of solid targets is advantageous for the synthesis of biocompatible nanomaterials . It enables the physical generation of nanoparticles with outstanding purity as compared to conventional manufacturing methods for metals in various liquids, for example water, polymer‐doped organic solvents, and monomers . This technique works without the need of chemical precursors that potentially cause side effects on cell behavior or change the morphology of the desired polymer matrix.…”

Size and shape effects on the nonlinear optical behavior of silver nanoparticles for power limiters

“…The most widely used methods for the preparation of metal nanoparticles are based on chemical reactions in solution (also often termed wet chemistry) that yield metal nanoparticle colloids with specific surface properties and narrow size distribution functions [20]. Recent advances in pulsedlaser ablation in liquid or solid targets have led to a novel route enabling the generation of nanoparticles with outstanding purity [21][22][23][24].…”
