Abstract: Starch is an important natural polymer, due to the availability, low cost, and renewable and biodegradable properties. The plasticized starch is soft, which is similar to the elastomer. It would be very important in reducing cost and environmental protection if plasticized starch can be partly used to replace thermoplastic elastomers to toughen polymers. At present, starch is usually used as fillers to reduce the cost during polymer blending, but it can rarely be used to toughen polymer and prepare high impact polymer blends. In order to improve the mechanical properties of polymer/starch composites, many methods such as plasticizing modification of starch, chemical modification of starch, adding compatiblizers, adding elastomer and synergistic toughening of starch have been used. In this review, the research progress of polymer/starch composites is briefly introduced, and several methods to improve the properties of polymer/starch composites are also systematically described. At last, the problems in the application of starch in polymer blending modification are discussed, and the future development direction is prospected.
