comprises warming/heating the at least one primary capsule to a temperature that is no more than about 60°C,no more than about 55°C,no more than about 50°C,no more than about 45°C,no more than about 40°C,no more than about 39°C,no more than about 38°C,no more than about 37°C,no more than about 36°C,no more than about 35°C,no more than about 34°C,no more than about 33°C,no more than about 32°C,no more than about 3 1°C,no more than about 30°C,no more than about 29°C,no more than about 28°C,no more than about 27°Cor no more than about 26°C. In some embodiments, the template comprises a low boiling organic solvent. In one embodiment, the template comprises pentane. In various embodiments, the method does not comprise adding/providing a vesicle template. For example, the method may not comprise adding/providing a polymer emulsion such as a PNIPAM emulsion particle as a template. According, in various embodiments, the method does not comprise growing a shell such as a silica shell around a PNIPAM emulsion particle template. Therefore, in various embodiments, the method does not comprise calcination or high temperatures to remove a template. The methods disclosed herein may further comprise one or more post heterocoagulation steps. For example, the method may further comprise a step of purifying the hybrid/composite capsule formed in the mixture to remove any impurities such as excess/free polymer particles. The step of purifying the hybrid/composite capsule may comprise centrifuging the mixture, creaming the mixture, allowing the mixture to settle and subsequently decanting the mixture etc. Additional process engineering steps and automated additions or flow chemistry may also be introduced to avoid extra polymer particles without purification step. The method may also further comprise a step of subjecting the purified hybrid/composite capsule to a temperature cycle to form a film.
