Abstract

Abstract: Straw reinforced thermoplastic resin composites are environment-friendly materials which are widely used in different areas. The interface compatibility of the composites will directly affect the performance of the composites, which makes interface modification research a hot spot in recent years. This paper summarizes the current status of development and new progress in interface modification of straw reinforced thermoplastic resin composites in domestic and overseas. Several typical surface treatment methods are introduced. It mainly analyzes the application of two new methods:plasma treatment and enzyme treatment for the surface pretreatment of straw, and further illustrates the influence of maleic anhydride-grafted polyolefin compatilizer and silane or titanate low molecular weight coupling agent on the interface modification of the composites. Besides, this paper briefly analyzes future research trends of the interface modification of straw/resin composites, and further making a research on the compound treatment of straw fiber and the development of efficient, environmentally friendly and cost-effective interface modifier is the key to improve the straw / resin composite material application performance in the future.
