So modified bentonite is used properly as a filler in variety of polymer industries such as polystyrene (PS), polyethylene (PE), and polypropylene (PP) (Ean, et al, 2003;Alekseeva, et al, 2009;Alekseeva, et al, 2012).

T HE main aim of this research is to investigate the suitability of using a low-grade bentonite in poly vinyl chloride (PVC)/clay nanocomposites for electrical applications. Bentonite was modified using Benzalkonium Chloride (BAC) as cationic surfactant, then both raw and modified bentonite (RB and MB) were introduced as fillers in mixture with PVC resin, plasticizer and stabilizer to produce PVC insulation compound for cables manufacturing. X-ray diffraction (XRD) and X-ray fluorescence (XRF) analysis were carried out to investigate the mineralogical and chemical composition of bentonite sample. Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM) and contact angle (CA) tests were performed on PVC insulation compound to investigate the interaction and compatibility between bentonite and PVC. Further investigations were established to characterize mechanical, thermal, and electrical properties of PVC compounds. The bentonite sample results show that bentonite is of low-grade bentonite. PVC/ clay insulation compounds results show that compatibility between PVC and bentonite increases in case of using modified bentonite (MB), therefore, the hydrophobicity of resulted PVC compound increased. Moreover, PVC/ MB nanocomposites show better mechanical properties (such as tensile strength and elongation at break) than PVC/ raw bentonite (RB) nanocomposites;the tensile strength values have increased from 21.1, 20, 19.1, and 18.2 N/mm2 for 2.5, 5, 7.5, and 10 phr of RB, respectively, for PVC/RB nanocomposite samples to 22.4, 21.3, 20.5, and 20 N/mm2 for the corresponding PVC/MB nanocomposites, On contrast, PVC/ RB nanocomposites give significantly better thermal properties (thermal stability) and electrical properties; the volume resistivity were decreased from 1.071012 for PVC/RB nanocomposites 10 phr of RB for to 5.86×1010 Ω•cm for the corresponding PVC/MB nanocomposite.

“…Effective way to solve this problem is to modify the polymer matrix by fillers insertion. Such composites may have applications in such various areas of industry as sensors, sorbents, catalysts, and membranes, as well as in biochemistry and medicine as drug templates, due to their improved mechanical, electrical, thermodynamic, antimicrobial properties (Badamshina and Gafurova, 2008;Alekseeva et al, 2009Alekseeva et al, , 2012Alekseeva et al, , 2013Weng et al, 1999;Yang and Nelson, 2006;Hwu et al, 2002). Note polymers modified using the filling agents considerably change their original parameters and acquire improved physicochemical properties even at small filler concentrations (Badamshina and Gafurova, 2008).…”

Effect of the bentonite filler on structure and properties of composites based on hydroxyethyl cellulose, Arabian Journal of Chemistry (2015), doi: http://dx. AbstractGranulometric test and morphological analysis of the bentonite particles were performed using laser diffraction and low-temperature nitrogen adsorption-desorption techniques. Bentonite particles were immobilized into the hydroxyethyl cellulose matrix by mechanical dispersion, and composite films were obtained. The effect of concentration of the filling agent on structure and tensile properties of composites was revealed. Data on the nature of interaction between hydroxyethyl cellulose and bentonite after the modification of polymer was obtained by IR spectroscopy. It was found that the hydroxyethyl cellulose/bentonite composite films showed an antimicrobial effect against E. coli and Staph. aureus bacteria, as well against fungi association.
