Method for measuring particle size of microcapsule

The invention discloses a method for determining the particle size of a microcapsule. The method comprises the following steps: diluting a to-be-determined dehydrated microcapsule to obtain a diluted microcapsule solution; adding a dyeing solution into the diluted microcapsule solution to obtain a dyed microcapsule solution; photographing the dyed microcapsule solution through a camera microscope under a preset photographing condition to obtain a corresponding microcapsule picture; on the basis of a pre-calibrated standard ruler, manually scribing to measure the particle sizes of at least one group of microcapsules on the microcapsule picture; according to the determination method, microcapsule particle size determination is carried out based on a camera microscope, a standard scale calibrated by a static micrometer is used as a scale for particle size determination in determination, materials and equipment used in the determination method are common and easy to obtain, operation is simple and rapid, the rese
