embodiments, the method does not rely on coacervation to facilitate an integration of an organic material on or with a shell of the primary capsule. Furthermore, in various embodiments, the method does not rely on controlled radical polymerization such as surface-initiated atom transfer radical polymerization (ATRP), in situ polymerization and/or precipitation polymerization to facilitate an integration of an organic material on or with a shell of the primary capsule. In various embodiments, the heterocoagulating step does not comprise heterocoagulating a monomer with the shell of the at least one primary capsule. For example, in various embodiments, the method does not comprise precipitating organo-alkoxysilane monomer or vinyl monomer around a silica core/capsule. In various embodiments, the heterocoagulating step is at least partly carried out at a temperature that is within or close to, no less than, or higher than the glass transition temperature (Tg) range or melting temperature range of the organic polymer latex particles or the organic polymer from which the organic polymer latex particles are derived. Advantageously, this may aid the coalescence or merging or melting of the organic polymer latex particles to form a continuous film/coating over the surface of the shell of the primary capsule. Depending on the identity of the organic polymer latex particles used, the temperature applied to aid the coalescence or merging of the organic polymer latex particles may vary. Accordingly, a suitable temperature range may be used. For example, the heterocoagulating step may be carried out at a temperature of from about 10°Cto about 80°C,from about 15°Cto about 75°C,from about 20°C to about 70°C,or about 10°C,about 15°C,about 20°C,about 25°C,about 30°C, about 35°C,about 40°C,about 45°C,about 50°C,about 55°C,about 60°C,about 65°C,about 70°C,about 75°Cor about 80°C.
