Interfacial morphology effects

It is imperative to mention that component polymer surfaces and interfaces play a major role in the properties and applications of blends such as in biocompatibility, switching, or adaptive properties. Whether it is an everyday plastic part or parts in automotives or in an airplane, not only the development of interfacial morphology but also the analyses of blends interfaces are equally important. The compatibilizing effect is primarily due to the interfacial activity of the constituent partners. This in turn raises the question of what are the effects of the molecular weight, concentration, temperature, and molecular architecture of the...

Mechanical properties of natural fiber reinforced composites are mainly influenced by the level of dispersion and interfacial adhesion between the matrix and fibers and microscopy is one of the most effective methods for morphological observations. In this study, scanning electron microscope (SEM) was used to investigate the dispersion of natural fiber and interfacial morphologies and the images are shown in Figures 3.2 (film surface) and 3.3 (cryo fractured surface). The SEM pictures show the differently shaped particles and the more or less spherical lignin-based particles.
