Bioegradable Poly -carprolactone Microcapsules Contaning Microbe by Emulsion Solvent Evaporation method

摘要

PURPOSE: A manufacturing method of a microcapsule with impregnated microorganisms is provided to timely spatially control the emission of microorganism formulation and to prevent the moisture-absorption and the decomposition of the microorganism formulation. CONSTITUTION: A manufacturing method of a microcapsule with impregnated microorganisms includes the following steps: inner water phase(S1) containing a thickener and microorganisms and first organic phase(O1) containing an organic solvent and an emulsifier are mixed to obtain a W1/O1 emulsion; the W1/O1 emulsion is mixed with outer water phase(W2) composed of an aqueous emulsifier solution to obtain a W1/O1/W2 emulsion; second organic phase(O2) containing a polymer material and an organic solvent is mixed with the W1/O1/W2 emulsion to obtain W1/O1/W2/O2 emulsion; and the organic solvent of the first and second organic phase from the W1/O1/W2/O2 emulsion is evaporated.
