Shape of the microcapsules

The outer shape of the microcapsules depends on the type of material in the core and the method of depositing the wall material. Microcapsules may be smooth, spherical particles and grape-like conglomerates or irregular particulates with smooth or rough surfaces. 

The shape of the microcapsules is usually that of the encapsulated substance and the cover thickness depends on the microencapsulation conditions and is varied according to the intended uses of the products. It may be possible to process the resulting composition directly into goods (e.g. by pressing), or the polymeric cover may enable better combination of the nanoparticles with other polymers.
