K. Berdjane, D.Benachour; S. Bensaad

Abstract
The present study consists of surface modification of industrial sodium montmorillonite (MT-Na) by cold plasma treatment. In order to increase its compatibility with polyethylene, a gas precursor, carbon tetrafluoride (CF4) is used in this physical process. The treated MT-Na is characterized by X-ray photoelectron spectroscopy. Prepared samples of LDPE/MT-Na and LDPE/MT-CF4 mixtures are characterized by Fourier transform infrared spectroscopy (FTIR); scanning electron microscopy (SEM); differential scanning calorimetry (DSC); tensile and dynamic rheology tests.
