Tailored Nanocomposites of Polypropylene with Layered Silicates
The melt rheological properties of layered silicate nanocomposites with maleic anhydride (MA) functionalized polypropylene are contrasted to those based on ammonium-terminated polypropylene. While the MA functionalized PP based nanocomposites exhibit solid-like linear viscoelastic behavior, consistent with the formation of a long-lived percolated nanoparticle network, the single-end ammonium fu...
متن کاملDielectric properties of plasma sprayed silicates subjected to additional annealing
Several silicate materials were plasma sprayed and characterized by the authors in recent years from the point of view of their chemical and phase compositions, microstructure and mechanical as well as thermal properties. Present work is concerned with selected dielectric properties of these deposits. Synthetic mullite and steatite as well as natural olivine-forsterite were plasma sprayed using...
متن کاملPolymerically modified layered silicates: an effective route to nanocomposites.
Polymer/clay nanocomposites have been under an extensive investigation for about 15 years. Traditional methods to modify the clay are usually limited to small organic cations, preferably containing long alkyl chain(s), which are exchanged with the inorganic cations in the clay gallery. This article provides a comprehensive review on the strategies for clay modification using polymeric surfactan...
متن کاملDielectric Relaxation of Diethylsulfoxide
The dielectric loss spectrum of the title substance has been measured in its pure liquid state between 10 MHz and 72 GHz at 20°C. In comparison to the Debye function, it is slightly broadened towards the high frequency side. The maximum corresponds to a relaxation time of 51 ps. In view of the molecular size and viscosity, this is relatively long and thus indicative of associative intermolecula...
