Abstract

Sb-SnO2/potassium titanate (SSP) composites were synthesized by densely coating Sb-doped SnO2 on the surface of fibrous-like potassium titanate. X-ray diffraction demonstrated that Sb was successfully doped into the crystal lattice of SnO2. To improve the dispersion of SSP composites in the acrylic resin, the as-prepared SSP was modified with sodium stearate. Fourier transform infrared spectra, thermogravimetric analysis, and transmission electron microscopy confirmed that stearate radicals existed on the surface of SSP in the form of physical adsorption. The hydrophilic degree of modified SSP was largely improved by water contact angle measurements. The properties (surface resistivity and mechanical properties) of the conductive coatings prepared by adding the obtained composites were investigated in detail. The modified SSP coatings exhibit more superior electrical conductivity due to their better dispersion in the matrix compared with SSP. Moreover, the obtained composite coatings present high pencil hardness of 4H–5H and excellent adhesion force, flexibility, and impact resistance.

Keywords: conductive coating; potassium titanate whisker; Sb-SnO2; sodium stearate; surface modification
