AbstractConsiderable effort has been devoted to thesynthesis of liquid filled microcapsules and nanocapsules owing to their general usefulness. The DCM solution was combined with an equal volume of the aqueous solution of sodium dodecylsulfate (SDS), and the biphasic mixture was subjected to high-power ultrasound treatment. Furthermore, it is likely that the interlocking of the polymer chains in the hydrophobic layer of the capsule shells leads to objects that are strong and stable. It is worth noting that the cryo-TEM images were obtained for a sample that was more than 30 days old. The self-assembly of capsule shells and their stability depend on the nature and size of both hydrophobic and hydrophilic polymer blocks.
