WebMar 30, 2001 · Transesterification of polymer blends containing polyesters is often utilized to improve the interfacial adhesion and mechanical properties of a phase-separated blend. However, in some circumstances, the transesterification can also modify the morphology (crystallinity or liquid crystallinity) of the blend components due to the disruption of ... WebThe formation of nanoparticles and the mechanism of their formation in a blend of a thermotropic liquid crystalline polyester (LCP) and the zinc salt of a lightly sulfonated polystyrene ionomer (Zn-SPS) were investigated using Fourier transform infrared (FTIR), thermogravimetric analysis (TGA), and gas chromatography–mass spectroscopy …
WebPolymer Morphology • Morphology is the science of form and structure. It provides the link between the molecular structure and the bulk properties. • As applied to polymers, morphology involves the study of the arrangementof polymer molecules into crystalline and amorphous regions. WebIn addition to the development of phase morphology, crystalline morphology was investigated. The MFCs without an amorphous phase were analysed via SEM under high magnification. The spherulite structure developed in most of the samples, and a random orientation of the lamellae was noted in bulk polymer, as well as some spherulite …
