Description of the data | Publication: 3D Characterization of Dry Particle Coating Structures originating from the Mechano-Fusion Process A model particle system of alumina (host particle) and polystyrene (guest particle) is processed using mechano-fusion. Samples from three experiments with different process parameters (rotational speed and process time) are characterized concerning the resulting coating structures of guest particles on the surface of the host particle. Therefore, particle samples are prepared for a qualitative SEM analysis and quantiative micro-CT analysis. From the 3D micro-CT data, the structural descriptors coating thickness, coating efficiency and neighbooring behavior of the guest particles are quantified. The influence of the process parameters on the coating structures is discussed. | |

Abstract of the dataset | During the mechano-fusion experiments for particle coating available process data (time, rotational speed, temperature, power, torque) is recorded. Samples of alumina coated with polystyrene from three different experiments were scanned using the Zeiss Xradia 510 Versa X-ray micro-CT. The samples were prepared by dispersing coated particles over carbon tape, which was subsequentely rolled up. | |

Project abstract | The project "Agglomeration Applying High Intensity Mixing (Mechano-Fusion)" is part of the priority program 2289 "Hetero-Aggregates" funded by the German Research Foundation (DFG). Hetero-aggregates are created by the dry particle coating process called mechano-fusion. The surface of larger host particles is coated with micron- or submicron-sized guest particles, an ordered mixture of guest particles on the surface of host particles is formed. Specialized functionality of the created hetero-aggregates is the a result of hetero-contact formation during the coating. Intensive characterization of the coating structures using 2D and 3D imaging and correlative worflows by scanning electron microscopy (SEM), X-ray micro- and nano-computed tomography (micro-CT and nano-CT) and atomic force microscopy (AFM) is expected to unravel mechanisms of underlying micro processes (e.g. agglomeration, de-agglomeration, mixing) during the coating. Toghether with stocastic modeling this will enable to tailer functionalities of hetero-aggregates even better. | |
