Study findings from C. Racles et al broaden understanding of macromolecular research

  2008 NOV 24 - (VerticalNews.com) -- "The micellization of a polysiloxane-ketimine has been studied in solvents of different polarity, i.e., dimethylformamide (DMF) and toluene. The critical micelle concentration was determined from surface tension measurements -in DMF-, and from viscosity variation with concentration," scientists writing in the journal Macromolecular Rapid Communications report.

  "Metal complex nanoparticles have been synthesized from this macromolecular ligand in DMF and in toluene, using the formed micelles as templates. Spectroscopic data (IR and UV-vis) confirmed the metal complexation," wrote C. Racles and colleagues.

  The researchers concluded: "TEM observations revealed the formation of nanoparticles with different morphologies, which were consistent with the assumed conformation of the ligand in solutions of the two selective solvents."

  Racles and colleagues published their study in Macromolecular Rapid Communications (Micellization of a siloxane-based segmented copolymer in organic solvents and its use as a tool for metal complex nanoparticles(A). Macromolecular Rapid Communications, 2008;29(18):1527-1531).
