Fullerene C60 and its derivatives as nanocomposites in polymer nanofibres

This work describes the application of oxo-derivatives of fullerene C60 and pristine fullerene as a nanocomposite in polymerous nanofibres. In this work we used oxofullerene derivative, of which preparation was presented by the authors of the State office for nuclear safety (Prague) on Nanocon 2009 and on Nanocon 2010 [1, 2]; there was presented its application in vivo as a radioprotective agen...

On the Effective Permeability of Mixed Matrix Membranes

Mixed matrix membranes (MMMs) are attracting significant interest for pervaporation and gas separation applications. To better comprehend the impact of filler particles within polymer matrices, the species permeation mass transport was theoretically studied by numerical simulation using finite differences. The Fick’s second law of diffusion was solved for a three-dimensional MMM to obtain the c...

Role of attached polymer chains on the vibrational relaxation of a C60 fullerene in aqueous solution

We have investigated the vibrational relaxation of a bare C60 fullerene and C60 fullerenes with covalently attached poly ethylene oxide PEO chains in aqueous solution using classical molecular dynamics simulations. The rate of transfer of vibrational energy from the excited fullerene to the surrounding water was found to be slow for the bare fullerene, with a vibrational relaxation time of appr...

Purified and Functionalized MWCNTs: Application In CO2/CH4 Separation Using Mixed Matrix Membranes

   To fabricate a defect free and high performance mixed matrix membrane (MMM), one approach is the functionalization of inorganic nanofillers (as dispersed phase) in the organic polymer matrix (as continuous phase) to modify the interactions between two phases.  For this purpose,, raw multi-walled carbon nanotubes (rMWCNTs) were purified by acid mixture (HNO3/H2SO<sub...
