Stable super-hydrophobic lauryl methacrylate film fabrication on the surface of cotton fabrics in plasma-enhanced chemical vapor deposition with different duty cycles

Abstract

In this paper, stable super-hydrophobic lauryl methacrylate (LMA) film on the surface of cotton fabrics was fabricated by a simple process of pulsed plasma-enhanced chemical vapor deposition (PECVD) with different duty cycles. The influence of duty cycles on the surface structure and properties of cotton fabrics was analyzed after a series of measurements. The results showed that water contact angles (WCAs) of samples were inversely proportional to the duty cycle values and exhibited the highest WCA (162°) at a duty cycle of 2%. The optimized washing durability of samples was obtained under the treatment of duty cycle of 25% and the WCA could still reach 127° after 15 laundering cycles. The formation of a micro-nano-composite structure and evenness of film could be observed by atomic force microscopy and scanning electron microscopy. Nevertheless, the sample, which was treated by plasma with a 25% duty cycle, had the best uniformity of film deposition. The results of attenuated total reflection Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy illustrated that the LMA monomer was grafted and deposited on the surface of cotton fabrics successfully in covalent binding after PECVD treatment, and this was supposed to be the cause of the washing stability of the films. The results indicated that cotton fabrics modified with the proposed method can exhibit excellent super-hydrophobicity and washing durability, while the duty cycle was an appreciable effect factor in the modification.

Fabrication of a Flexible Si-cotton Filter Membrane for Efficient Hot Oil/Hot Water Separation

“…A hydrophobic/oleophilic cotton textile is developed by plasma polymerization of PDMS solution, which is a green and economical source of Si-based polymers for plasma. Cotton is a low-cost material with excellent flexibility and can be considered as a suitable substrate to fit working conditions [30,31]. Furthermore, cotton surface with its hydrophilic hydroxyl groups can be easily functionalized by physical or chemical treatments and used for oil-water separation [32,33].…”

The Effect of Hydroxyl on the Superhydrophobicity of Dodecyl Methacrylate (LMA) Coated Fabrics through Simple Dipping-Plasma Crosslinked Method

“…In our past research, we used dodecyl methacrylate (LMA) as the monomer via the plasma-enhanced chemical vapor deposition (PECVD) method [21][22][23] and the immersion-plasma-induced crosslinking method [24], respectively, to successfully prepare durable superhydrophobic cotton fabric, and it was found that the superhydrophobicity of cotton fabric made by the immersion-plasma-induced crosslinking method had better durability. Therefore, in this paper, cotton, PET, thermoplastic polyurethane (TPU) and polyamides-6 (PA6) fabrics were treated by LMA and low-voltage capacitively coupled discharge plasma (LP-CCP) via the immersion-plasma-induced crosslinking method, and the performances of the cotton and PET fabrics were compared to probe the influence of the presence of hydroxyl groups on the properties of LMA-coated fabrics.…”
