Abstract
Wax microspheres encapsulating flavour or fragrance oil (L-carvone, Hexyl salicylate) prepared via melt dispersion was investigated. This study highlights the influence of different waxes as well as variable oil loadings on the fundamental properties of the resulting microparticles. The mechanical characterisation of individual wax microspheres by a micromanipulation technique is firstly reported here and the values of Young's modulus of wax microspheres were determined by fitting the experimental force versus displacement with the Hertz model. The relation between the payload and Young's modulus of wax microsphere was also explored in this study.
期刊介绍：
Polymer Testing focuses on the testing, analysis and characterization of polymer materials, including both synthetic and natural or biobased polymers. Novel testing methods and the testing of novel polymeric materials in bulk, solution and dispersion is covered. In addition, we welcome the submission of the testing of polymeric materials for a wide range of applications and industrial products as well as nanoscale characterization.
The scope includes but is not limited to the following main topics:
Novel testing methods and Chemical analysis
• mechanical, thermal, electrical, chemical, imaging, spectroscopy, scattering and rheology
Physical properties and behaviour of novel polymer systems
• nanoscale properties, morphology, transport properties
Degradation and recycling of polymeric materials when combined with novel testing or characterization methods
• degradation, biodegradation, ageing and fire retardancy
Modelling and Simulation work will be only considered when it is linked to new or previously published experimental results.
