“…The bands observed at 2969 cm À1 , 1712 cm À1 , and 1094 cm À1 in the spectrum of the composite originate from aliphatic C-H stretching, C=O stretching and C-O stretching of PET, respectively. While the bands at 1572 cm À1 and 1485 cm À1 correspond to the C=C stretching mode of the quinoid and benzenoid rings of the POA coat on the composite [31], respectively, the band observed around 1460 cm À1 can be attributed to the C-H bending of the ÀOCH 3 group of POA [32].…”

A conductive poly(o-anisidine) (POA)/poly(ethylene terephthalate) (PET) nonwoven composite was prepared by chemical oxidative polymerization of o-anisidine in aqueous HCl solution. The effects of the oxidant type, oxidant/monomer mol ratio, and polymerization temperature and time were studied on POA content and surface resistivity of the composite. It was observed that the swelling of PET in 1,4-dioxane decreased the surface resistivity of the POA/PET composite by up to 18.5 k/cm 2 , when compared to that of the unswollen PET nonwoven. According to the electromagnetic shielding effectiveness (EMSE), and the relative shielding efficiency of the absorbance (A b ) and reflectance (R e ) values of the composite in the range 15-1500 MHz, 99.9% of the shielding was obtained with an attenuation of 33 dB at 15 MHz. The durability of the composite was determined by measuring its surface resistivity after domestic washing and commercial laundering.
