To improve the interfacial compatibility between bamboo fiber (BF) and polylactic acid (PLA) matrix, pyrrole was oxidatively polymerized on the BF surface continuously under different oxidizing conditions. The untreated and modified BF/PLA composites were fabricated via a melt extrusion process. Polypyrrole (PPy) was successfully coated on the surface of the BF, Furthermore, the four oxidants (hydrogen peroxide, copper chlorid, ferric chloride, ammonium persulfate) showed different effects on PPy modified composites. When the ferric chloride as the oxidant, the modified composites exhibited 22.79 %, 33.43 %, and 37.58 % improvement in flexural strength, tensile strength, and impact strength compared with the control sample, while achieving significant enhancements in thermostability and antistatic due to the presence of PPy. This work provides a new promising way for fabricating the antistatic, excellent mechanical property BF/PLA composites.

为了提高竹纤维（BF）与聚乳酸（PLA）基质之间的界面相容性，吡咯在不同的氧化条件下在BF表面连续进行氧化聚合。未经处理和改性的BF / PLA复合材料是通过熔体挤出工艺制造的。将聚吡咯（PPy）成功地涂覆在高炉的表面上。此外，四种氧化剂（过氧化氢，氯化铜，氯化铁，过硫酸铵）对PPy改性的复合材料表现出不同的作用。当氯化铁作为氧化剂时，与对照样品相比，改性复合材料的弯曲强度，拉伸强度和冲击强度提高了22.79％，33.43％和37.58％，同时由于存在而使热稳定性和抗静电性显着提高PPy。
