Author:Ogunniran, ES; Sadiku, R; Ray, SS; Luruli, NDate:Dec 2011Boehmite alumina nanoparticles are added to PP-g-MAH-compatibilized blends of PA 12 and PP to study the effects of nanoparticle loading in the resulting composites. WAXD and SEM data suggest that the nanoparticles enhanced the coalescence of ...Read more
Author:Adegbola, TA; Rotimi, SE; Suprakas, Sinha RDate:Apr 2016The compounding of rPAN/PET [polyacrylonitrile/poly(ethylene terephthalate]; 30/70, 50/50, and 70/30 wt %) using a melt-blending technique was the main focus of this investigation. An X-ray diffraction study indicated the possibility of ...Read more
Author:Mavuso, MA; Makgwane, Peter R; Ray, Suprakash SDate:Nov 2020The effective Ce3+/Ce4+ redox and oxygen mobility of CeO2 induced by tunable nanostructure morphology has attracted a great interest in photocatalytic organic synthesis. Herein, we report on the microwave‐assisted synthesis of CeO2 with ...Read more
Author:Mngomezulu, ME; Luyt, AS; Mathew, Maya JDate:Dec 2017This work reports on the effect of expandable graphite (EG) on the morphology, thermal and dynamic mechanical properties of flame retardant poly(lactic acid) (PLA)/EG composites. The composites were prepared by melt-mixing and their structure, ...Read more
Author:Wokadala, OC; Ray, SS; Bandyopadhyay, J; Wesley-Smith, J; Emmambux, NMDate:Aug 2015Polylactide/butylated-starch/nanoclay (70/25.5/4.5 wt%) composites were prepared by melt blending with nanoclays of varying hydrophobicity. Electron microscopy studies indicated that the interphase boundary interaction was highest in the clay ...Read more
