Özet

CuS nano particles synthesized by a sonication process were deposited onto oxidized multi-wall carbon nanotubes (MWCNTs) dispersed in maleic anhydride octane 1 (MAO) copolymer matrix. MWCNTs were prepared by catalytic chemical vapor deposition from ethylene over a Co, Fe/alumina catalyst, MAO was grafted with oxidized MWCNTs under sonication at 353 K for 3 h. CuS nanoparticles were prepared from copper acetate dihydrate and thiocarbainide in this matrix while heating for 2 h. The resulting nanocomposite matrix featured uniform MWCNT dispersion and a peculiar foam-like morphology which was attributed to the effect of ultrasonic cavitation. The mean diameter of the obtained embedded hexagonal CuS nanoparticles was 3.2 nm. The optical band gap of the final product was calculated to be 2.28 eV which suggests that the CuS MWCNT MAO nanocomposite can be evaluated as a potential solar protection material.
