Synthesis, characterization and impregnation of lead sulphide semiconductor nanoparticles on polymer matrix

Abstract EN

Lead sulphide nanoparticles were prepared using a precursor and dual sources methods.

The composites were fabricated by stabilizing chemically synthesized semiconductor PbS nanocrystals into laurylmethacrylate and ethyleneglycol dimethacrylate matrix in the presence of tri-n-octylphosphine.

PbS nanocrystals were dispersed in toluene as a compatible medium for the polymerization and cross-linking of poly laurylmethacrylate networks.

The nano-sized particles and polymer composites were characterized by XRD and TEM.

Possible formulations and incorporation of these PbS nanoparticles in polymer matrix have been discussed.

The reported lead sulphide nanoparticles into tailered polymeric system show greater uniformity and stability.
