Abstract
The present disclosure relates to a method for size-selective separation of 2-dimensional plate particles using spherical particles. Since the separation method of 2-dimensional plate particles according to the present disclosure is simple, economical and extensible to large-scale applications, it can contribute greatly to commercialization of plate particles by reducing cost and preventing deterioration of physical properties. The 2-dimensional plate particles having uniform size can be useful in such applications as transparent electrodes, solar cells, composites, drug delivery, biosensors, etc.
Claims14
A method for size-selective separation of 2-dimensional plate particles, comprising:
- (a) mixing a dispersion of positively charged 2-dimensional plate particles with a dispersion of negatively charged spherical particles and stirring to obtain a mixture solution comprising unbound 2-dimensional plate particles and aggregates wherein the 2-dimensional plate particles are bound to the spherical particles;
- and
- (b) separating the unbound 2-dimensional plate particles from a supernatant obtained by precipitating the aggregates in the mixture solution comprising the unbound 2-dimensional plate particles and the aggregate.
