Transmission electron microscopy (TEM) is a unique tool to visualize polymer morphology: an intimate organization of the matter, encompassing crystalline features in semicrystalline polymers and a kaleidoscopic collection of patterns produced by microseparated phases in polymer blends. This manuscript aims at demonstrating the various opportunities this technique enables, through a miscellany of studies performed in our laboratory. Materials as different as bulk and composite compounds, thin films, hollow fiber membranes, and rubbers are presented, from the viewpoint of the interrelation of TEM with other techniques like scattering, mechanical, and thermomechanical experiments.
Polymer morphology, which encompasses a luxuriant collection of patterns produced by microseparated phases in polymer blends, composites, or semicrystalline polymers, has a crucial impact on the macroscopic properties of these materials. Transmission electron microscopy is a unique tool to investigate these intimate organizations, in interrelation with scattering and thermomechanical experiments.
