Abstract

SUAREZ, Oscar; OLAYA, Jhon J  and  ALFONSO, José E. Synthesis and structural characterization of sulfonated styrene divinylbenzene copolymers as stabilizers for metallic nanoparticles. Rev. LatinAm. Metal. Mater. [online]. 2016, vol.36, n.1, pp.70-77. ISSN 0255-6952.

Nanostructured metallic materials can have an industrial potential because these materials have chemical and physical properties different from those of the same materials in bulk. Therefore, sulfonated styrene-divinylbenzene copolymers were synthetized, and the porosity, solubility and degree of sulfonation were measured for the selection of the polymeric matrix. Polymer/metal nanocomposites of bismuth and tin were obtained via ultrasonic radiation in a medium of dimethylformamide using a nonionic surface agent stabilizer. Differential scanning calorimetry (DSC) was used for identification of the reaction products. Long term stability of tin and bismuth-tin metal/copolymer solutions may indicate that nanometric metal particles were obtained.

Keywords : metallic nanoparticles; polymer; nanocomposites; Tin; Bismuth.
