▎ 摘 要
NOVELTY - Process for synthesis of carbon beads involves preparing a viscous slurry in a non-polar solvent configured to function as a disperse phase, where the viscous slurry is prepared using at least one of a binder, a crosslinker molecule, a radical polymerization initiator and a carbon material and each of the binder and the crosslinker molecule comprises terminal carbon double bond groups and a spacer group, preparing a viscous gel using hydrocolloids, where the viscous gel is configured to function as a continuous phase; passing the disperse phase and the continuous phase into a microfluidic droplet generator to obtain spherical droplets of a predefined size; subjecting the spherical droplets to one of a thermal treatment and UV radiation to obtain spherical particles of carbon beads; and drying the spherical particles of carbon beads to obtain the carbon beads of a predefined dimension. USE - The process is useful for synthesis of carbon beads used in separation, filtration, purification, wires and cables, electrodes, sensor, composite and additive manufacturing and pharmaceutical delivery applications. ADVANTAGE - The process provides the carbon beads of spherical structures with controlled size, morphology, porosity and physico-chemical properties, enables modulation of the viscous slurry for synthesis of the carbon beads with improved physico-chemical properties and enhances ability of the carbon beads to withstand extreme pH and high temperatures.
