Synthesis and structural characterization of sulfonated styrene divinylbenzene copolymers as stabilizers for metallic nanoparticles
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.
