Author:Ojijo, Vincent O; Ray, Suprakas S; Sadiku, RDate:May 2014Polylactide (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 ...Read more
Author:Dutta, S; Sengupta, S; Chanda, J; Das, A; Wiessner, S; Ray, Suprakas S; Bandyopadhyay, ADate:Mar 2020In this article distribution of nanoclay between the two phases of a new class of dynamically vulcanized TPV based on POE/EVA(Polyethylene octene elastomer/ethylene vinyl acetate copolymer) elastomers prepared with various amounts of organoclay ...Read more
Author:Bandyopadhyay, J; Ray, SS; Bousmina, MDate:Aug 2007The 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
Author:Malwela, T; Ray, SSDate:Jun 2015Films 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
Author:Hato, MJ; Choi, HJ; Sim, HH; Park, BO; Ray, SSDate:Feb 2011Soft 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
Author:Gcwabaza, T; Suprakas, SR; Focke, WWDate:Oct 2008Forming 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
Author:Malwela, T; Ray, Suprakas SDate:Sep 2014This 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. ...Read more
