最后，吡咯单体在棉表面Fe3+的作用下迅速聚合为聚吡咯，聚吡咯的R1(

Finally, the pyrrole monomer is rapidly polymerized into polypyrrole under the action of Fe3+ on the cotton surface. The R1(R2)-NH2 of polypyrrole is acidified and protonated to R1(R2)-NH+, R1(R2)- under the hydrolysis of FeCl3. NH+ binds to the carboxyl group of SA through electrostatic attraction to adsorb SA, and binds to the -OH on the cotton surface through hydrogen bonding.

Finally, pyrrole monomer rapidly polymerizes into polypyrrole under the action of Fe3 + on the cotton surface. R1 (R2) - NH2 of polypyrrole is protonated into R1 (R2) - NH + under the hydrolysis of FeCl3. R1 (R2) - NH + binds to the carboxyl group of SA through electrostatic attraction, adsorbs SA, and binds to - oh on the cotton surface through hydrogen bond.<br>

At last, pyrrole monomer is rapidly polymerized into polypyrrole under the action of Fe3+ on cotton surface, and R1(R2)-NH2 of polypyrrole is acidified and protonated into R1(R2)-NH+ under the hydrolysis of FeCl3, and R1(R2)-NH+ is bound with carboxyl group of SA by electrostatic attraction to adsorb SA, and will be bound with -OH on cotton surface by hydrogen bonding.
