从图3（a）中可以明显的看到棉织物进行改性过程中材料表面元素成分的变化

From Figure 3(a), we can clearly see the changes in the surface element composition of the cotton fabric during the modification process. The CF, which is mainly cellulose, only shows the C1s and O1s peaks. After being soaked in FeCl3, the Fe element appears in the broad sweep spectrum. The peak area of ​​C1s in CF-SA modified by stearic acid increased significantly, indicating that SA was successfully modified on cotton fabric. An obvious N1s peak appeared after the last modification, which indicated that the pyrrole successfully polymerized on the surface of the material.

It is obvious from Figure 3 (a) that the composition of the material surface elements changes during the modification of cotton fabrics. The main body is cellulose's CF with only C1s and O1s peaks, and after FeCl3 immersion, fe elements appear in the scan wide spectrum. The C1s peak area in CF-SA after stearic acid modification increased significantly, indicating that SA was successfully modified on cotton fabric. The apparent N1s peak after the last modification indicates that the aggregation reaction occurs successfully on the surface of the material.

It can be seen from Fig. 3 (a) that the change of surface element composition of cotton fabric in the process of modification. Only C1s and O1s peaks appeared in CF with cellulose as the main component. After soaking in FeCl3, Fe appeared in the scanning broad spectrum. The C1s peak area of cf-sa modified by stearic acid increased significantly, which indicated that SA was successfully modified on cotton fabric. After the last step of modification, there was an obvious n1s peak, which indicated that pyrrole was successfully polymerized on the surface of the material.<br>
