A Comparative Analysis of Various Types of Modified Bentonite Clays Added to Poly Methyl Butadiene for Nanocomposite Preparation

Fayq Hsan Jabbar and Wisam A. Latif

Abstract

New Nano-composite of biopolymers was prepared for this analysis. The natural bentonite clay group forms Na- Bentonite (Na- BTT), K- Bentonite (K- BTt), and Ca- Bentonite (Ca-Btt) has been modified by the addition of synthesized fatty amide (FACO), namely Corn oil (CO). To achieve the modification the clay particles was mixed thoroughly in an aqueous (FACO) solution which increases the separation of the clay layer from 1.25 to 2.75 nm of BTT, 1.17 to 1.34 nm of BTt and 1.14 to 1.31nm of Btt due to the action exchange capacity of Na- BTT which is much greater than the low cation exchange capacity of K- BTt and Ca-Btt, respectively. The improved Na- BTT was then used in the preparation of poly methyl butadiene (PMB) Nano-composite. The modifiers interaction in the clay layer is described by X-ray diffraction (XRD). A conventional approach was used to synthesize the Nano-composite, in which the modified clay (FACO- BTT) was melt mixed with PMB. To classify the Nano-composite XRD, Transmission Electron Microscopy (TEM) and Thermogravimetric have been used. The results of XRD and TEM confirmed Nano-composite growth. In contrast to pure PMB, PMB modified BTT Nano-composite showed higher thermal stability. The use of FACO as a vegetable oil derivative to modify clay would minimize reliance on petroleum based surfactants. Moreover, such Nano-composites are considered environmentally friendly in addition to being renewable resources.
