Abstract:

Polyaniline was deposited on a polylactide nonwoven by the in situ method in the form of emeraldine salt (Green Protonated Emeraldine), i.e. by oxidative polymerisation on the fibre surface. The nonwoven was also padded with a solution of Blue Emeraldine Base. Depending on the type of polyaniline (PANI) deposited, the resulting samples showed different conductance values. Changes in electrical resistance were assessed versus the procedure of final treatment. Thermogravimetric measurements showed an increase in the temperature of decomposition of about 50 °C compared to that of an unmodified sample. The nonwoven with the deposited layer of PANI was overlaid with a layer of complexing polymers by the layer-by-layer method. The effect of such a modification on the electro-conductive (resistance) and sorption properties of nonwovens was examined.
