Abstract:
In this work, a dye is encapsulated using alginate and polyethylene glycol dimethacrylate (PEGDMA). 3 types of shell materials were studied: alginate alone, alginate with PEGDMA irradiated directly by UV irradiation to start the polymerization of PEGDMA, and alginate with PEGDMA irradiated after 24h . These three types of capsules were characterized to study the size, the morphology, the mechanical properties and the water quality analysis. this showed that the capsules irradiated directly probably trapped calcium and didn’t allow it to crosslink the alginate chains and water quality was not affected by the dissolution of any type of capsules.
