Preparation and thermal characterisation of poly(lactic acid) nanocomposites prepared from organoclays based on an amphoteric surfactant
journal contribution
posted on 2013-01-10, 15:46 authored by Andrew R. McLauchlin, Noreen ThomasNew polymer-clay nano-composites composed of poly(lactic acid) and a novel
organoclay based on cocamidopropylbetaine (CAB) and sodium
montmorillonite (MMT) were prepared by solution casting and characterised
by X-Ray Diffraction Analysis (XRDA), Transmission Electron Microscopy
(TEM) and Thermogravimetric Analysis (TGA). A similar series of composites
based on PLA and Cloisite 30B, a commercially available organoclay, were
prepared for comparison. The thermal stability of the CAB-MMT organoclays
decreased with increasing surfactant loading. Experimental organoclays with
an organic content similar to that of the commercial organoclay were found to
be of comparable thermal stability. XRDA analysis of the PLA-organoclay
nano-composites showed that PLA intercalated the gallery space of both
types of organoclay to similar extents and the increased spacing was
confirmed by TEM. The thermal stabilities of the PLA-organoclay composites
based on CAB-MMT were higher than those based on the commercial
organoclay.
