Abstract: The perfect coating agents were prepared by use of the Mini-tab DOE anlysis experiment with the ratio of nano-tuber PANIs and the hydrochloric PANIs,the dosage of CNT adulterant,the dosage of bonds and the dosage to fabric.The four factores were analyszed by testing the surface resistant of the coating fabric.The lowest surface resistance of coating fabric is 16 Ω,the highest SE (shielding effectiveness of microwave) is 48 dB,according to a series of coating technique experiments on single factor,the dosage of agent.So the conductivity and SE of the fabric was improved greatly,the techniques have important applications in development of the anti-electromagnetic wave,conducting electricity,anti-electrostatics,electronic warm fabric or costume.
