Abstract
The present invention provides for a process for synthesis of carbon beads comprising sub-micron size, micron size or milli size. The process enables modulation of the viscous slurry for synthesis of the carbon beads with improved physico-chemical properties. The process enhances ability of the carbon beads to withstand extreme pH and high temperatures. The present invention also provides a composition for synthesis of the carbon beads. The present invention also provides a microfluidic droplet generator for synthesizing the carbon beads. The carbon beads synthesized by the present invention are applicable in separation, filtration, purification, wires and cables, electrodes, sensor, composite and additive manufacturing, pharmaceutical delivery applications.
Claims18
A process for synthesis of carbon beads, comprising:
- preparing a viscous slurry in a non-polar solvent configured to function as a disperse phase,
- wherein the viscous slurry is prepared using at least one of a binder, a crosslinker molecule, a radical polymerization initiator, and a carbon material,
- wherein each of the binder and the crosslinker molecule comprises a plurality of terminal carbon double bond groups and a spacer group,
- wherein the spacer group is a compound comprising at least one of hydrophilic chains, amphiphilic chains and any combination thereof;
- preparing a viscous gel using one or more hydrocolloids, wherein 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.
