Yield Improvement and Durability Enhancement of Hollow Microcapsules Fabricated by Bubble Template Method

抄録

We investigated the effects of the containing gas and gelatin addition on the yield and durability of hollow microcapsules fabricated by the bubble template method. Low-solubility sulfur hexafluoride gas-based hollow microcapsules were smaller-sized and higher in yield than the nitrogen gas-based ones. Moreover, the undamaged hollow microcapsules remaining after a durability test increased after gelatin addition. These results were attributed to the stability of low-solubility bubbles and the reaction promotion of gelatin on encapsulation.
