The study of size and stability of n-butylcyanoacrylate nanocapsule suspensions encapsulating green grass fragrance
Green grass fragrance has been widely used in many fields.However,fragrances are volatile compounds that do not last long.In order to prolong its odor,nanocapsules encapsulated green grass fragrance were prepared.The paper deals with the preparation of green grass fragrance nanocapsules by emulsion polymerization.N-butylcyanoacrylate(BCA)with excellent biocompatibility and biodegradability was used as encapsulant.The nanocapsule suspension systems were characterized and its stability was investigated.The physicochemical properties of polymeric nanocapsules(average diameter and polydispersity)were evaluated as a function of time to assess the system stability.The result showed that the system(containing 0.8%of green grass fragrance,with a polydispersity index(PDI)near 0.1 and an average diameter in the range of 20-30 nm)was an ideal state and relatively stable.Besides,the distinction of stability of three nanocapsule suspensions with different green grass fragrance content was also obvious from scanning electron microscopy(SEM).
