Concurrent Enhancement of Multiple Properties in Reactively Processed Nanocomposites of Polylactide/Poly[(butylene succinate)-co-adipate] Blend and Organoclay

Author: Ojijo, Vincent O ; Ray, Suprakas S ; Sadiku, R Date: May 2014 Polylactide (PLA) and poly[(butylene succinate)-co-adipate] (PBSA) were reacted by being blended in a batch mixer in the presence of a chain extender, triphenyl phosphite (TPP), and two different types of organically modified clays—a ...

Effect of organoclay on the orientation and thermal properties of liquid-crystalline polymers

Author: Bandyopadhyay, J ; Ray, SS ; Bousmina, M Date: Aug 2007 The preparation and thermal and thermo-mechanical properties of nanocomposites based on liquid-crystalline polymers (LCP) and organically-modified layered silicate (OMLS) is described. From XRD patterns, very little smectic ordering is present ... Read more
Effect of Organoclay on the Properties of Maleic Anhydride-Grafted Polypropylene and Poly(methyl methacrylate) Blend

Author: Hato, Mpitloane Joseph ; Motaung, David E ; Choi, Hyoung Jin ; Scriba, Manfred R ; Khumalo, Vincent M ; Malwela, Thomas Date: Mar 2017 Poly(methyl methacrylate)/polypropylene (PMMA/PP) and PMMA/maleic-anhydride grafted PP (MAPP) blends and their blend nanocomposites containing 2 wt% organoclay (Cloisite 15A, denoted C15A), prepared by a melt mixer were studied. Both X-ray ... Read more
Enzymatic degradation behavior of nanoclay reinforcedbiodegradable PLA/PBSA blend composites

Author: Malwela, T ; Ray, SS Date: Jun 2015 Films of a biodegradable PLA/PBSA blend and blend-composites containing 2 wt% of C20A, C30B and MEE were prepared by solvent casting and spin coating. The films were incubated in vials containing Tris–HCl buffer with Proteinase K, and their ... Read more
Magnetic carbonyl iron suspension with organoclay additive and its magnetorheological properties

Author: Hato, MJ ; Choi, HJ ; Sim, HH ; Park, BO ; Ray, SS Date: Feb 2011 Soft magnetic carbonyl iron (CI) based magnetorheological (MR) fluids containing three different loadings of submicron-sized organoclay were prepared. The MR characteristics were measured via rotational and oscillatory tests, in which the ... Read more
Morphology and properties of nanocomposites based on polymer blend and organoclay

Author: Gcwabaza, T ; Suprakas, SR ; Focke, WW Date: Oct 2008 Forming a polymer blend is a convenient method for obtaining materials with improves property performance. However, most chemically different polymers are immiscible and their blending leads to a material with weak interfacial adhesion and ... Read more
Role of organoclay in controlling the morphology and crystal-growth behavior of biodegradable polymer-blend thin films studied using atomic force microscopy

Author: Malwela, T ; Ray, Suprakas S Date: Sep 2014 This study reports the effect of organically modified nanoclay on the morphology and crystal growth behavior of biodegradable polylactide/poly[(butylene succinate)-co-adipate] (PLA/PBSA) blend thin films with the average thickness of 280 nm. ...
