Deagglomeration and mixing via the rapid expansion of high pressure and supercritical suspensions
… enhanced turbulent shear stress, and thereby deagglomeration, also enhanced mixing, however this effect could be obscured by inhomogeneities introduced by the feed mixtures. Previous authors have suggested that the primary deagglomeration mechanism is the explosive expansion of the carbon …

Mixing of nanoparticles in a stirred tank in high pressure carbon dioxide
… to mixing. One of the techniques to achieve deagglomeration and mixing of nanoparticles is based on rapid depressurization/expansion of supercritical suspensions. where the suspension of initially premixed agglomerates in supercritical CO_2 pass through the nozzle undergoing deagglomeration …

Advanced Thermoplastic Nanocomposite Melt Processing Using an Improved Supercritical Carbon Dioxide Pretreatment for the Nanomaterial
… of this work is to develop a method for the deagglomeration of commercially available multi-walled carbon nanotubes (MWCNTs) by manipulating processing variables and observing carbon nanotube aspect ratios after deagglomeration. High levels of deagglomeration of Baytubes C 150 P and Nanocyl …

Mixing of nanosize particles by magnetically assisted impaction techniques
… at different length scales, one could achieve deagglomeration and subsequent mixing at varying length scale. A better understanding of this can have a major impact on the field of nano-structured materials; thus the long term objective of this project is to gain fundamental understanding of …

Factors Affecting Fiber Orientation and Properties in Semi-Flexible Fiber Composites Including the Addition of Carbon Nanotubes
… the super critical carbon dioxide aided deagglomeration of multi-walled carbon nanotubes (CNTs) was used to create injection molded multiscale composites with CNT, CF, and polypropylene. The addition of CNTs greatly improved the tensile and electrical properties of the composites compared …

An investigation into the precipitation of Fe(III) oxyhydroxides in lime neutralization processes
… However, these imaging results show evidence of deagglomeration at 50 °C which probably explains the improved dewatering behaviour. The batch ageing system revealed that structural maturation in the ageing process, at elevated temperature, has multiple particle rate processes that occur …
