Silver and Copper nano-colloid generation via Pulsed Laser Ablation in Liquid: Recirculation nanoparticle production mode

Abstract

Metal nanoparticles have unique chemical, physical, electrical, and optical properties that make them attractive for a wide range of applications in sensing, anti-fouling surfaces, medicine, and conductive inks. Pulsed Laser Ablation in Liquid (PLAL) is a green method of nanoparticle colloid production, capable of producing ligand-free nanoparticles in solution without the need for hazardous, environmentally unfriendly chemicals. Control of the process parameters can give control over the resulting colloid properties such as particle size distribution. In this work, silver (Ag) nanoparticles (NPs) with average particle size from 2.04 to 19.3 nm and copper (Cu) NPs with average particle size from 40 to 85.9 nm were produced by PLAL) technique.

Production of Silver Nano-Inks and Surface Coatings for Anti-Microbial Food Packaging and Its Ecological Impact

“…A peristaltic pump (Millipore Ltd., Burlington, VT, USA) was used to maintain a recirculating flow of DI-water over the AG target surface at 100 mL min −1 . The flow-cell was composed of a main structure of VeroWhitePlus (RGD835) photopolymer produced by a Stratasys Connex1 Polyjet 3D printer, an EPDM O-ring and a quartz laser window [ 19 , 26 ].…”

Silver nanocolloid generation using dynamic Laser Ablation Synthesis in Solution system and drop-casting

“…Evaporation condensation and laser ablation are two important physical processes that are implemented. Laser Ablation Synthesis in Solution (LASiS) is a physical technique that synthesizes NPs in liquid media [15][16][17][18][19][20][21][22] using laser energy, unlike wet-chemical synthesis methods which use environmentally harmful reducing agents. The process involves a pulsed laser focused on the surface of a solid target in a liquid environment, ablating material from the target and producing ligand free NPs.…”

Silver Nano-Colloid Characterization for Printing Application

“…repetition rate, pulse duration, wavelength, and laser fluence) and the target material. The LASiS technique is capable of producing additive free non-toxic stable colloidal dispersions of nanostructures (e.g., aluminium [32], carbon [33], gold 34], nickel [35], copper [36], carbon nanotube [37], and silver [38]) in both organic and aqueous media. Therefore, the eco-friendly, cost effective LASiS technique has received much attention for the industrial production of conductive functional nanomaterials.…”
