Preparation Of Conductive In Situ Polymerization Of Polymer Fabric Via Ultrasonic Radiation Methods

In this paper, polyaniline and polypyrole fabrics were fabricated on alkali treatedpolyeaster fabric via in situ polymerization under ultrasonic radiation..In the preparation of polyaniline conductive fabric, studied two oxidation system ofammonium persulfate （APS） and H₂O₂/Fe²⁺for preparating polyaniline conductive fabric. Theoptimum condition of prepared excellent conductive properties of polyaniline conductivefabric in ammonium persulfate oxidation system was aniline and ammonium persulfateconcentration was0.4mol/L, the concentration of hydrochloric acid1.4mol/L, ultrasonicimmersion time1h, power180W, oxidation time45min and temperature10℃,its Surfaceresistance was55. Then, the effects of camphorsulfonic acid doped, were doped differenttypes of surfactants and coupling modified polyester fabric for the preparation of polyanilineconductive fabric were been studied. After concentration of0.4mol/L camphor sulfonic aciddoped150min reduced the Surface resistance of polyaniline conductive fabric to35; Doped2%sodium dodecyl benzene sulfonate increased the conductive properties of polyanilineconductive fabric; The Surface resistance of polyaniline conductive fabric reached33,which prepareted after by the5%coupling602modified polyester fabric. The polyanilineconductive fabric was characterized by SEM、IR、XRD、TG and electromagnetic shieldingeffectiveness testing,et. The results show that: through SEM observated that the fabric surfaceadsorpted a layer of uniform and dense polyaniline film, which was confirmed by IR test;XRD test showed polyaniline infiltrated in the fiber, which resulted the degree of fabriccrystallinity decreased; TG test showed that polyaniline penetrated in the PET fabric anddoped surfactant caused the thermal stability of fabric reduced. ultrasonic radiation effectivelyinhibited PANI chain brush-like orientation; added sodium dodecyl benzene sulfonate plaied arole of prevent growth of polyaniline polymerization and implosion; coupling602becomed the "molecular bridge" of aniline and fabric,what improved the loading of polyaniline on thefabric.In the preparation of polypyrrole conductive fabric, Studied the optimal process ofpreparat polypyrrole conductive fabric and the effect of different surfactants doped forpreparating polypyrrole conductive fabric. The optimal of preparated polypyrrole conductivewas the concentration of pyrrole and ferric chloride were0.2mol/L, pyrrole monomerultrasonic immersion1h, oxidation time1h, power200W, bath ratio1:50and temperature10℃,et. The Surface resistance of polypyrrole conductive fabric achieved7. Used SEM、IR、XRD、 TG、 electromagnetic shielding effectiveness testing and environmental stabilitytesting.et characterized polypyrrole conductive fabric characterization. IR tests showedpolypyrrole absorpted the fabric surface, the polypyrrole like cauliflower on the surface offabric was observed by the SEM. XRD test showed polypyrrole penetrated into the interior ofthe fabric, which resulted the degree of fabric crystallinity increased; TG test showed thatdoped surfactant caused the thermal stability of fabric reduced. The polypyrrole conductivefabric preformaned good stability; The electromagnetic shielding effectiveness of thepolypyrrole conductive reached19dB, which had certain electromagnetic shielding effect.
