Green polymer materials are one of the important means to solve the global challenge of plastic pollution.Sustainable material is widely studied,but the blend with various high properties has been less explored.Herein,high-performance and fully green multiphase blends were prepared by a melt-process-ing method from thermoplastic starch(TPS),poly(butylene adipate-co-terephthalate)(PBAT)and a series of novel hydroxyl-functionalized ionomers.The influence of the ionomer and composition on phase structure and physical properties of the blends were thoroughly investigated.The ionomer played multiple roles in the system as a plasticizer for TPS,toughening agent and compatibilizer for the blend.Working together with glycerol,the ionomer effectively improves the physical performance of TPS.More important-ly,by intertwining between the TPS and PBAT phases through intermolecular interaction,the ionomer ef-fectively enhanced the compatibility of the blend,offering comprehensive performance in combination of balanced mechanical property,and anti-aging properties.The elongation at break of TPS(12-40％)/PBAT 20/80 is 436％after 30 days.The study has important implications for developing sustainable high-performance composites from natural products and bioplastics by IL-containing polymers.
