Microscopy of polymer blends and polymer composites for 3D printing

The increasing demand for polymeric materials with special bulk and surface properties has led to a variety of strategies for the development of new materials aimed at synergistic effects through combinations of polymeric materials. Polymer blending is an attractive field for scientific and industrial investigation because it is a simple method to obtain new materials with improved performance without having to produce new polymers. Immiscible polymer blends form two discrete phases and compatibilization is necessary to achieve maximum synergy. 3D printing or additive manufacturing is fabrication of a three-dimensional object using a 3D digital model. The term 3D printing can refer to a range of processes in which material is applied, bonded, or solidified by computer control to create a three-dimensional object, typically adding the material (e.g., plastics, liquids, or powder grains that are fused together) layer by layer. Over the past ten to twenty years, 3D printing has evolved into a technology that enables the production of complex, yet cost-effective 3D components. As 3D printing technologies become more affordable, it seems inevitable that this technology will become the tool of choice for manufacturing flow reactors and other reactionware. The talk will present examples of the development of polymer blends and polymer composites for 3D printing, as well as an overview of their properties. The influence of the filler addition on the morphology of the polymer blends and the influence of the surface properties of the fillers on the selectivity of placement within the polymer blends will be presented. A brief overview of the appearance of the surfaces of 3D printed objects depending on the printing settings and the possibilities of modifying these surfaces by plasma treatment with the aim of adjusting the hydrophobic properties will be given.
