The effect of synthesis condition on physical properties of epoxy‐containing microcapsules

Abstract: The physical properties of microcapsules are largely influenced by the synthesis conditions such as weight ratio of core/shell material, agitation rate, reaction time, and different emulsifier. Different synthesis condition would lead to different property. It is an important issue for application in composites that require self-healing microcapsules possessing rough surface morphology, less adhesion, less core material permeability, appropriate diameter and core content, and adequate shell thickness. The prop… Show more

“…Other factors, including encystation reaction time, reaction temperature and ionic strength, also can influence drug preparation and release (Angelova & Hunkeler, 2001;Varma et al, 2004). Different synthesis conditions or parameters, such as the agitation rate, emulsifiers or weight ratio of core/wall materials may also result in different properties of microcapsules (Wang et al, 2011). The optimum reaction conditions were as follows: the agitation rate at 250 rpm, the core/wall material weight ratio of 1.4:1, 1.5% of emulsifier sodium dodecyl benzene sulfonate, and the reaction time for 3 hr, which affects the surface morphology and core permeability of microcapsules (Wang et al, 2011).…”

“…The capacity to self-healing results in prolonged material service life, less maintenance, and hence potential cost reductions. [1][2][3][4][5][6][7][8][9][10][11][12][13][14] The self-healing of thermoset polymer-based composites (primarily epoxy) has garnered increased attention because these composites are an important class of structural materials that especially require long-term stability. The self-healing agent is generally encapsulated and embedded in the composites' matrix, and as soon as the microcapsules are ruptured, the self-healing agent is released into the crack planes to react with the self-healing agent.…”
