Abstract
Poly(methyl methacrylate-co-methacrylic acid) lead(II) salt ionomer [P(MMA-co-MAA)−PbII] has been prepared by the exchange reaction of poly(methyl methacrylate-co-methacrylic acid) with lead(II) acetate. PbS nanoparticles were synthesized by treating the [P(MMA-co-MAA)−PbII] powder with H2S. The average PbS particle size was estimated to be ∼1−10 nm, depending on the preparation conditions. The particle size was found to increase with the increasing concentration of the carboxylic−lead(II) salt group content. Fourier transform infrared, UV−vis, X-ray diffraction, transmission electron microscopy, and differential scanning calorimetry techniques were employed to study the size, interfacial structure, and thermal properties of the PbS nanocrystals in the copolymer matrix.
