Manufacturing and characterization of water filled micro-composites
The goal of the present work was to manufacture water-filled micro-composites using a high pressure encapsulation process, PGSS (Particles from Gas Saturated Solutions), and to characterize the products by different analytical methods. As shell material a vegetable fat (hydrogenated Castor oil) is used. The obtained composites have tailor made properties like bulk density, particle size, morphology and water content. A special interest was laid on the distribution of water (core material) within the composites. Water distribution is studied using two different methods: H NMR and DSC. The analytical results suggest the presence of three different "types" of water: water between the particles, entrapped and bound water (c) 2012 Elsevier B.V. All rights reserved.
