  2010 MAR 8 - (VerticalNews.com) -- "The materials science community has identified nanoparticle dispersion as a primary challenge area for the advancement of polymer nanocomposites technology. Although nanoparticle dispersion can significantly impact important engineering properties, it is not itself a quantifiable property: qualitative TEM image assessments remain as the 'gold standard' for dispersion characterization," scientists in the United States report ...read more

  2010 MAR 8 - (VerticalNews.com) -- "Functionalized multiwalled carbon nanotubes (F-MWNTs) were prepared by covalent grafting of five-armed star polylactide (fa-PLA), and were characterized by thermogravimetric analysis (TGA), nuclear magnetic resonance (NMR) spectroscopy and Raman spectroscopy. A series of polylactide (PLA)/F-MWNTs composites was prepared via coagulation method," scientists writing in the journal Polymer report ...read more

  2010 MAR 8 - (VerticalNews.com) -- "Polyamide nanocomposites with fair balance of mechanical properties were recently obtained by addition of finely dispersed clay-compatibilized rubber or rigid PS phase. This work deals with combination of both components, which recently led also to enhanced mechanical behaviour in an analogous reactively compatibilized ternary system," scientists writing in the European Polymer Journal report ...read more
