چکیده

In this study, we developed an apparatus by combining n-hexane electrospray and atmospheric pressure argon plasma jet for deposition diamond like carbon (DLC)layer as a hydrophobic film on cotton textile. n-Hexane was used as a hydrocarbon precursor for preparing ionized spray for atmospheric pressure plasma (APP) jet. Inorder to characterize the plasma, electrical measurement and optical emission spectroscopy (OES) were employed. The electron excitation temperature of the APPwas estimated by Boltzmann plot method. Water contact angle (WCA) measurement was used to evaluate the hydrophobicity of the samples. The results showed thatthe water contact angle of these samples increases after treating by a combination of n-hexane electrospray and the APP jet. Considerations of aging effect on thesamples clarified that the samples coated with longer times show better withstand against aging effect. Washing durability investigation of the samples showed thatthe hydrophobic property of the samples has acceptable durability in 50 washing cycles. Formation of diamond like carbon (DLC) coating on the substrates wasproved by Raman and X-ray photoelectron spectroscopy (XPS) then characterized by FE-SEM analysis, energy dispersive spectroscopy (EDX) and X-Map probe. Theresults of this work were compared to the original one whose liquid precursor was ethanol. It was concluded that n-hexane precursor could result in betterhydrophobicity comparing with that of ethanol precursor
