Supercritical CO2 assisted metallization of polyethylene terephthalate yarns with various twist number
This study investigates the metallization of polyethylene terephthalate (PET) yarns with varying twist numbers using the supercritical CO2 (scCO2) catalyzation process. The research includes an analysis of the impact on surface morphology, crystallinity, and electrical resistance. The crystallinity of the PET yarns is affected by treatment in pure scCO2 and scCO2 containing palladium hexafluroacetylacetonate (Pd(hfa)2), which is the scCO2 catalyzation process and Pd(hfa)2 is used as the Pd catalyst source. Furthermore, this study uncovers the influence of the twist number on the fiber surfaces where the fibers come into contact in the twisted yarn. Specifically, the electrical resistance decreases with an increase in the twist number, attributed to an increase in conductive pathways and improved contact points between the fibers.
期刊介绍:
The Journal of Supercritical Fluids is an international journal devoted to the fundamental and applied aspects of supercritical fluids and processes. Its aim is to provide a focused platform for academic and industrial researchers to report their findings and to have ready access to the advances in this rapidly growing field. Its coverage is multidisciplinary and includes both basic and applied topics.
Thermodynamics and phase equilibria, reaction kinetics and rate processes, thermal and transport properties, and all topics related to processing such as separations (extraction, fractionation, purification, chromatography) nucleation and impregnation are within the scope. Accounts of specific engineering applications such as those encountered in food, fuel, natural products, minerals, pharmaceuticals and polymer industries are included. Topics related to high pressure equipment design, analytical techniques, sensors, and process control methodologies are also within the scope of the journal.
