The content(wt%) of coated pPy in the coated fabrics was controlled by the number of treatments(these two steps). This study examined the effect of the number of treatments/pPy content on the sheet resistance, mechanical/bending properties and color behaviors of pPy coated fabrics. The coated pPy content, sheet resistance(Ω/square) and color strength(K/S) of pPy coated fabrics increased sharply with increasing number of treatments up to 20 times, while the increase slowed down afterward. The tensile strength, elongation at break and lightness(L*) decreased with increasing number of treatments. The tensile modulus and bending rigidity of coated fabrics increased significantly with increasing number of treatments/coated pPy content. This indicated that the flexibility of coated fabrics decreased considerably.
