Abstract: The recent developments in the modification of interface adhesion in poly- (hydroxybutyrate-co-hydroxyvalerate) (PHBV)/ natural botanic fiber degradable biocomposite are reviewed. A good interface adhesion between natural botanic fibers and PHBV is achieved by the interface modification of natural botanic fiber，addition of compatilizer，and the chemical modification of PHBV matrix，with the natural fiber dispersing much better in the matrix. The advantages and disadvantages were compared，and such material’s future are discussed.

摘要： 总结了近年来国内外关于聚羟基丁酸酯-co-羟基戊酸酯共聚物（PHBV）/天然植物纤维复合材料界面改性的研究进展。从天然植物纤维表面改性、在PHBV和天然植物纤维体系中添加界面改性剂以及对PHBV树脂基体进行改性等方面，来增强天然植物纤维与PHBV界面结合力，并使纤维在PHBV基体中分散更好。同时比较了这些改性方法的优劣，展望了此类材料的发展前景。
