Dual microcapsulation of an environmentally-friendly-based reactive multifunctional acrylated epoxy resin and thiol by internal phase separation technique for self-healing applications

In this research, the microcapsules were individually prepared via internal phase separation technique using reactive bio-based acrylated epoxidized soybean oil, AESO, and trimethylolpropane tris(3-mercaptopropionate), TMPMP as healing and curing agents respectively in PMMA shell for self-healing in...
