Effect of gamma irradiation on the properties of natural rubber latex and styrene‐butadiene rubber latex nanocomposites
Source abstract
Abstract
Natural rubber (NR)/clay and styrene–butadiene rubber (SBR)/clay nanocomposites were prepared by mixing with aqueous sodium montmorillonite (Na+‐MMT) clay dispersion by different concentrations of Na+‐MMT ranging from 2 to 10 phr. These nanocomposites were irradiated with gamma radiation at doses from 10 to 100 kGy. X‐ray diffraction (XRD) results indicated well dispersion of rubber latex into clay stacked layers and the platelets have a preferential orientation forming exfoliated NR/Na+‐MMT nanocomposites while SBR/Na+‐MMT form intercalated nanocomposites. Irradiation overall irradiation dose range together with clay loading improve the mechanical properties of rubber/Na+‐MMT nanocomposites. However, SBR nanocomposite attains its higher value at 50 kGy, then decrease. Also, the thermal stability at 50 kGy is higher than 100 kGy. POLYM.
