Characterization of Microcapsules Prepared by Interfacial Polycondensation of Methylene Bis(phenyl isocyanate) with Hexamethylene Diamine
Polyurea microcapsules containing 2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide as the active agent were prepared by the method of interfacial polycondensation with methylene bis(phenyl isocyanate) as the multifunctional isocyanate, hexamethylene diamine as the diamine, and anionic sodium lignin sulphonate as the emulsifying agent . Thermal stability of the microcapsules was investi...
متن کاملPreparation of Microcapsules Containing Erythritol with Interfacial Polycondensation Reaction by Using the (W/O) Emulsion
It was tried to microencapsulate erythritol as a phase change material with the interfacial polycondensation reaction method by using the (W/O) emulsion and to characterize the microcapsules prepared. In the experiment, toluene diisocyanate, diphenyl methane diisocyanate and hexamethylenediisocyanate were used to form the polyurethane shell and the effects of them on the heat storage density an...
متن کاملPolyurea microcapsules in microfluidics: surfactant control of soft membranes.
Interfacial polymerization techniques offer a versatile route for microcapsule synthesis. We designed a microfluidic process to synthesize monodisperse polyurea microcapsules (PUMCs); the microcapsules are formed by an interfacial polymerization of isocyanate dissolved in the oil and an amine dissolved in water. We measure the mechanical properties of the capsule as well as transport properties...
متن کاملControlling the morphology of polyurea microcapsules using microfluidics.
We use microfluidics to continuously produce monodisperse polyurea microcapsules (PUMCs) having either aqueous or nonaqueous cores. The microcapsule shells are formed by the reaction between an isocyanate, dissolved in oil, and an amine, dissolved in water, at the surface of oil-in-water or water-in-oil drops immediately as they are formed. Different microcapsule morphologies can be generated u...
متن کاملLITERATURE ON CONTROLLED RELEASE DRUG DELIVERY SYSTEMS (MICROCAPSULES AND MATRIX TABLETS) Controlled release drug delivery systems
Controlled release drug delivery systems 1 are those dosage formulations designed to release an active ingredient at rates, which differ significantly from their corresponding conventional dosage forms. The controlled release drug delivery systems are aimed at controlling the rate of drug delivery, sustaining the duration of therapeutic activity and/or targeting the delivery of the drug to a ti...
