Special Issue Information

Dear Colleagues,

Modern microscopic technologies have become indispensable for research and development in almost all scientific fields. Zooming-in, and making even the smallest structure details visible, is of crucial importance for material designs and understanding of structure/property relationships. Polymers often possess an already complex morphology, which depends not only on their molecular structure, but also on the processing parameters, and which becomes even more complex when these polymers are mixed with other polymers, with fillers or with, e.g., semiconductive components in micro- and nanodimension.

Well-known techniques such as transmission electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscopy (AFM) or light microscopy (LM) are still the basis for polymer microscopy but have developed rapidly in recent years, becoming more versatile and adaptable according to the type of materials to be investigated. For example, electron tomography using TEM tilt series or serial sections from SEM/focused ion beam measurements now provides insights into the third dimension; material properties can be quantitatively determined in the nanometer range using new AFM techniques, and in situ microscopy makes the formation of polymer structures understandable, to name just a few developments.

The scope of this Special Edition includes developments and applications of new microscopy techniques, but also investigations of interesting polymer systems with conventional microscopy methods. Therefore, polymer researchers focusing on material designs as well as researchers working on new technique developments are equally encouraged to participate in this Special Issue.

Abstract
Matt polyurethane coating was successfully prepared through the synergistic effect of castor oil and phenolic epoxy resin into polyurethane backbone. The formation mechanism may be ascribed to the modulus mismatch between the partially modified epoxy polyurethane and partially unmodified polyurethane. Scanning electron microscopy [...] Read more.
Matt polyurethane coating was successfully prepared through the synergistic effect of castor oil and phenolic epoxy resin into polyurethane backbone. The formation mechanism may be ascribed to the modulus mismatch between the partially modified epoxy polyurethane and partially unmodified polyurethane. Scanning electron microscopy (SEM) was used to observe the micro-rough surface morphologies. Atomic force microscopy (AFM) and three-dimensional (3D) surface profilometer were applied to calculate a series of surface roughness parameters in different dimensions, such as Sa, Sq, Sp, Sv, Sz, Sku, Ssk, etc. The exciting results of this paper—the correlation of surface roughness on measurement length and gloss—are explored in detail. It reveals the extrinsic property of measured roughness with measurement length and provides guidance for what kind of incident angle gloss meters (20°, 60°, and 85°) best describe the gloss of matt polyurethane coating.
