Average Size

Microcapsules had Urea Formaldehyde (UF) shell and linseed oil core were investigated manufacture. Synthesis UF shell of Microcapsules was experimented by emulsion polymerization and pH was only adjusted once by mixer of Resorcinol / Amoni Clorua. Content of Urea and emulsifiler Sodium Dodecyl Sulphate, pH, agitation rate were investigated. This research shows that the linseed oil (core) is disintegrated at 1,500 rpm in pH = 5.5 with 1.2% (w/w) Sodium Dodecyl Sulphate. In addition, the combination of Urea used in order to create the shell about 40% (w/w) linseed oil and Formaldehyde are suitable. The microcapsules products have the average size less 100 μm. Besides that, the content of the linseed oil in the core is about 87% (w/w)take the advantage to use in self-healing coating.

The Difference

Microencapsulation forms an integral part in synthesizing bioinspired materials. This paper focuses on elaborating the problems faced in encapsulation of DGEBA microcapsules in PMMA and urea formaldehyde shell wall. The preparation process and the process parameters affecting the microcapsule property are discussed. The difference between the microcapsules prepared using emulsion polymerization and that by solvent evaporation has been discussed. The size, shape and morphology of the microcapsules was characterized using FESEM technique. It was observed that the agglomeration of the microcapsules can be prevented by changing the concentration of the emulsifier. However, in case of urea formaldehyde encapsulation chunks of pre-polymer resulted in agglomeration of the nanosized capsules even if higher concentration of emulsifier was implemented.
