Synthesis and factor affecting on the conductivity of polypyrrole: a short review

Exceptional electromagnetic interference shielding and microwave absorption properties of room temperature synthesized polythiophene thin films with double negative characteristics (DNG) in the Ku-band region

3D Printing/Interfacial Polymerization Coupling for the Fabrication of Conductive Hydrogel

Nitrogen-Doped Porous Carbon/Graphene Aerogel with Much Enhanced Capacitive Behaviors

Recently, great efforts have been made to gain highly conductive fabrics for smart textiles and flexible electromagnetic shielding materials Different from the conventional chemical synthesis method, fibrillar polypyrrole was synthesized on the cotton fabrics via a simple chemical polymerization process with micelles of cationic surfactant (cetyltrimethylammonium bromide, CTAB) as soft template The modified cotton fabric exhibited excellent electrical conductivity and electromagnetic interference shielding effectiveness due to the formation of fibrillar polypyrrole on the fiber surface Electrical conductivity of fabric surface were studied by four-probe resistivity system The highly conductive fabric with surface conductivity of 58 S cm−1 could be obtained by changing cationic surfactant concentration The electromagnetic interference shielding effectiveness (EMI SE) of the modified fabrics was evaluated by the vector network analyzer instrument Compared with the sample without using surfactant, the EMI SE value of PPy-coated cotton fabrics increased by 28% after using 003 M CTAB as soft template © 2016 Wiley Periodicals, Inc J Appl Polym Sci 2016, 133, 43601

Enhancement in electrical conductive property of polypyrrole-coated cotton fabrics using cationic surfactant

Consequence of oxidant to monomer ratio on optical and structural properties of Polypyrrole thin film deposited by oxidation polymerization technique

The polythiophene thin films were prepared by a wellknown chemical bath deposition technique. The deposited thin films were characterized for structural morphological properties and the adhesion of these thin films were measured by direct pull off (DPO) method, the effect of oxidant concentration on these thin films also studied. The FTIR spectra of chemically deposited polythiophene thin films shows the absorption peak at 836 cm−1 which represents c–s stretching vibrations, shifts to 869 cm−1 as the oxidant concentration increases. The band at 666 cm−1 representing c–s–c ring deformation becomes sharper and appears with a shoulder peak due to increase in oxidant concentration.
