采用接触角测量仪、红外光谱等表征分析方法进行表征，研究了冷氧等离子体处理过程、处理时间、处理功率，以及处理结束后的保存时间等因素对竹粉／PETG复合材料的等离子处理时效性的影响。结果表明，经氧等离子体处理的试样，润湿性能明显增强，随着处理时间增加和处理功率的增强，液体在复合材料表面形成的接触角也越小，润湿性增强；随着等离子处理结束后保存时间的增加，处理的竹粉／PETG复合材料的改性效果逐渐减小，试样引入的—C眫O 等极性基团逐渐减少，表现为接触角变大并趋于平缓，表明经等离子体处理后复合材表面引入的极性基团的存在具有时效性。

By contact angle measurement instrument and infrared spectrum analysis , we studied the effect of processing time , plasma discharge power and holding time after plasma treatment on aging of surface functional groups of cold oxygen plasma treated bamboo flour/PETG composite.The processing time and discharge power increasing , the decay rate of surface func-tional groups initiated by cold oxygen plasma gradually retarded .With the retention time prolonging after treated , the mount of polar groups imported into surface of sample gradually decreased , and the functional groups aging of bamboo flour /PETG composite treated by cold plasma was mainly caused by reduction of -C=O groups.
