Microcapsules have been attracting attention as a means of releasing a functional substance to a target area or protecting it from an external environment. However recently, environmental pollution caused by microplastics commonly used in the synthesis of fabric softener has become a serious problem. Therefore, we are trying to develop a biodegradable microcapsule that solves the environmental problems and is expected to be effective in bioapplication. At first, we measured the biodegradability of microcapsule precursors by BOD/COD ratio. The microcapsules were synthesized by interfacial polymerization and it was confirmed that the size could be controlled by stirring speed. And also the residual isocyanate was measured by FT-IR and NMR. In later studies, further evaluation and bench scale experiments will be conducted to enable direct application as a fabric softener, and drug delivery studies will be conducted based on the biodegradable microcapsules. |
