Polypyrrole (PPy) coated cotton yarns were prepared by the vapour phase polymerisation technique at various initiator concentrations. Iron (III) chloride (FeCl3) was used as the initiator at four different concentrations (0.2, 0.4, 0.6 & 0.8 mol/l) respectively. In this work, the effects of initiator concentration on the tensile, electrical and morphological properties of the cotton yarns were investigated. PPy coated cotton yarns were woven on a handloom for the investigation of electromagnetic shielding effectiveness. The fabric samples prepared were evaluated in terms of shielding behavior. Scanning electron microscopy (SEM) analysis showed that the yarn treated with 0.4 mol/l initiator concentration gave the most uniform PPy layer and highest shielding value. The existence of PPy was proved by using Fourier transform infrared spectroscopy (FTIR) analysis.

Bawełniane przędze pokryte polipyrolem (PPy) wytworzono techniką polimeryzacji w fazie gazowej w różnych stężeniach inicjatora. Jako inicjator zastosowano FeCl3 o czterech różnych stężeniach (0,2; 0,4; 0,6 i 0,8 mol/l). Zbadano wpływ stężenia inicjatora na rozciąganie, oraz elektryczne i morfologiczne właściwości przędz bawełnianych. W celu zbadania efektywności ekranowania pola elektromagnetycznego przędze bawełniane powlekane PPy były tkane ręcznie na krośnie. Przygotowane próbki tkanin oceniano pod względem właściwości ekranujących. Analiza SEM wykazała, że z przędzy z dodatkiem inicjatora o stężeniu 0,4 mol/l uzyskano najbardziej jednolitą warstwę PPy i najwyższą wartość ekranowania. Obecność PPy potwierdzono za pomocą spektroskopii w podczerwieni z transformacją Fouriera (FTIR).
