Pulsed laser technology is a green and versatile method to produce nanoparticles with tailored properties. In this work, pulsed laser ablation in liquids (PLAL) has been employed to generate nanoparticles (NPs) of titanium and zinc oxides. A Q-switched Nd:YAG laser (Quantel Brilliant B, wavelength 532 nm, pulses of 4 ns, repetition rate 10 Hz) was used to produce the ablation of the metal targets. The production on NPs was done in different liquids (water, methanol, ethanol, isopropanol and ethylene glycol), which present different thermal conductivities, viscosities, and chemical properties. A complete characterization of the NPs (UV/Vis, DLS, TEM, AFM, Raman) was carried out to evaluate the NPs formed.
Surface properties of polymers are important for different applications such as their use as biomaterials, protective coatings, and thin film technology. We explore the formation of laser-induced periodic surface structures (LIPSS) on different polymers, investigating the influence of polymer nature, laser parameters, and environmental factors. By varying laser irradiation conditions, the study demonstrates control over LIPSS period and quality, surface chemistry, and properties like wettability, surface energy, and adhesion. Depending on the conditions, surface modifications can lead to increased hydrophilicity or hydrophobicity. These findings are essential for applications where surface interactions are crucial.
