Synthesis and characterization of metallic nanoparticles and their incorporation into electroconductive polymer composites

Thermal and Spectroscopic Properties of Polystyrene/Gold Nanocomposite Containing Well-Dispersed Gold Nanoparticles

“…The molecular structure of PS SH was determined by 1 H NMR and 13 and the Waters 410 differential refractive index (RI) detectors. The GPC was operated with four Waters Styragel HR Columns (HR 0.5, HR 3, HR 4, and HR5E) at a steady flow rate of 1 ml/min with a sample concentration of 0.1% in THF solvent.…”

“…[12][13][14][15] The preparation methods for polymer/nanoparticles composites with good particle dispersion have been broadly investigated in the past few years. [16][17][18][19][20][21][22] To alleviate the particle aggregation, these nanoparticles often require stabilization and several methods exist for stabilizing monodispersed metal nanoparticles, such as the methods using (1) ligands (Hostetler, 23 Schmid, 24 Gonsalves, 25 Youk et al, 26 Brown, 27 Maye et al, 28 Chechik, 29 and Takae et al 30 …”

“…13 C-NMR spectrum of PS SH . The two peaks of C c and the carbon of n-butyllithium (at ∼26 ppm) have the same height, indicating there is a perfect functionalization via end-capping the living polystyrene by ethylene sulfide.…”

Synthesis of Core-Shell (Pd-Au) Bimetallic Nanoparticles in Microemulsions

“…The first one involves the consecutive addition of two different metallic precursors in the reaction system. [3,22] Nanoparticles of one material are created in the initial times of the reaction to form the core of the nanoparticle. Over this core, a shell of a different material is deposited in the second part of the reaction.…”

“…They are followed by the controlled aggregation of the material. [9] These methods perform the synthesis in different environments: microemulsions, [17][18][19][20][21][22] solution, [10,13,23] a solid matrix, [24] etc. They use a number of reducing agents, including alcohols, hydrazine, polyols, borohydrides, light, sound waves, etc.…”
