![]() This study demonstrates that self-healing thermoset zein resin can be a promising green solution with longer service life, for a broad range of applications. This significant enhancement for OWMS healant is possibly due to covalent bonding with zein resin. ![]() Results indicated that zein resins with 15 wt WMSPLGA and OWMSPLGA MCs had self-healing efficiencies of 51 and 72 in fracture stress, respectively. While their rougher surface enhances the resin-MC mechanical bonding, higher aspect ratio increases the probability of MC being in the path of microcracks.Īlso, the OWMS, containing aldehyde groups, forms covalent bonds with zein, whereas WMS only provides H-bonding. Netravali Show more Get rights and content Abstract Self-healing green thermoset zein resin was developed using elongated multi-geometrical poly (D,L-lactic-co-glycolic acid) (PLGA) microcapsules (MCs) containing waxy maize starch (WMS) or oxidized WMS (OWMS) as healing agents.Ī novel method combining co-axial injection and emulsion-solvent evaporation technique was developed to fabricate multi-geometrical MCs with aspect ratios greater than 1.
