Translated title of the contribution: Effects of using different healing agents on healing efficiency in solid state self-healing system

Research output: Contribution to journalArticle

Abstract

Self-healing polymers possess the ability to heal in response to damage using resources inherently available to the system. The solid-state self-healing system was obtained by blending thermoplastic polymers into epoxy resin matrix. This study aimed to investigate the effect of polymer healing efficiency by using different thermoplastic polymers as healing agents which were poly (bisphenol-A-co-epichlorohydrin) (PDGEBA), polypropylene (PP) and polyethylene (PE). The bonding formed in the epoxy resins were characterized by means of Fourier transform infrared spectroscopy (FTIR). Healing was achieved by heating the fractured specimen to a specific temperature, above their glass transition temperature (Tg) to mobilize the polymeric chains of the healing agent. The Tg for each specimen was obtained from dynamic mechanical analysis (DMA). From the Izod impact test it was found that healable resin with PDGEBA has the highest healing efficiency followed by PP and PE, with 63%, 31% and 24% of average percentage healing efficiencies, respectively. These results were due to the different solubility parameters of the thermoset/network and thermoplastic polymer which led to the phase separation. The morphological properties and the fracture-healing process of the resins were then observed using optical microscope.
