Two different types of capsules were synthesized, one containing an initiator and one encapsulating a monomer, both in polyurethane shells. The monomer used was triethylene glycol dimethacrylate (TEGDMA). The initiator capsules synthesized contained benzoyl peroxide (BPO) and butylated hydroxytoluene. When released from the two types of nanocapsules, the encapsulated contents created a self-healing effect as the BPO initiated the TEGDMA to polymerize. The effects of the monomer capsules in epoxy resins were studied via tensile tests. The capsules reduced the strength of the resins; however, the capsules cracked during the resin fracture and a self-healing effect resulted.application:pdfbenzoyl peroxidedual capsulepolyurethaneself-healingTEGDMAText
