  2010 MAY 3 - (VerticalNews.com) -- "The assembling of magnetic nanoparticles in ordered structures as well as the preparation of very thin magnetic switchable polymer membranes is an important aim in many technical fields. We studied the influence of gamma-Fe2O3 nanoparticles on the polymerization process and on the properties of the poly(organosiloxane)/nanoparticle-composite layer by surface rheological measurements, surface pressure/area (pi/A) isotherm measurements, and Brewster angle microscopy," investigators in Dortmund, Germany report ...read more

  2010 MAY 3 - (VerticalNews.com) -- "A series of poly(lactic acid) (PLA)/poly(butylene succinate) (PBS)/layered silicate nancomposites were prepared by simple melt extrusion of PLA/PBS/Cloisite 30BX (organically modified MMT) clay. Extruded and compression moulded samples containing 1, 3, 5, 7 and 10 wt.% of clay having 80 and 20 wt.% of PLA and PBS respectively, were prepared to investigate morphological, thermal, mechanical and gas barrier properties of these biodegradable nanocmnposites," scientists writing in the journal International Polymer Processing report ...read more

  2010 MAY 3 - (VerticalNews.com) -- According to recent research published in the journal Polymers & Polymer Composites, "Multi-wall carbon nanotubes were purified by the mixed acid (HNO3 and H2SO4). The multi-wall carbon nanotubes/polyaniline composite (MWCNTs/PANI) was prepared by in situ polymerisation using aniline monomer and nanotubes in HCI solution."

  "The content of MWCNTs in the samples was 0 square 20 wt.%. The results showed that the MWCNTs were well dispersed in water after purification. The interaction between PANT and MWCNTs was proved by FT-IR spectrometry," wrote D.Y. Zhao and colleagues, Heilongjiang University ...read more
