In this paper, a super-hydrophobic cotton fabric was fabricated by low-pressure plasma-enhanced chemical vapor enhanced deposition (LP-PECVD) with lauryl methacrylate (LMA) as the functional monomer. Scanning electron microscopy (SEM), atomic force microscope (AFM) and X-ray photoelectron spectroscopy were used to analyze the changes of surface morphology and chemical composition of the cotton fabrics surface, respectively. A randomly wrinkled morphology was exhibited by SEM and AFM. The combination of the low surface energy film of LMA and micro-nano-scale structure resulted in the super-hydrophobicity of modified cotton fabrics. The reactive species in LMA/Ar plasma were studied by optical emission spectroscopy, and based on the results of the test, the reaction principle in the plasma reaction chamber was discussed. It was proved that the LMA film is polymerized by chemical bonds on the surface of cotton fibers. The water repellency, washing stability, water-vapor transmission, air permeability and tensile property of fabrics were also discussed. We found that a washing-stable and breathable super-hydrophobic cotton fabric can be achieved after treatment without decreasing the tensile property.

Polyolefins are considered among the most difficult polymeric materials to treat because they have poor adhesive properties and high chemical barrier responses. In this paper, an in-depth study is reported for the low pressure plasma (LPP) treatment of neutral polypropylene to improve adhesion properties. Changes in wettability, chemical species, surface morphology and roughness of the polypropylene surfaces were evaluated by water contact angle measurement, X-ray photoelectron spectroscopy and, furthermore, atomic force microscopy (AFM). Finally, the bonded joints were subjected to tensile tests, in order to evaluate the practical effect of changes in adhesion properties. The results indicate that plasma is an effective treatment for the surface preparation of polypropylene for the creation of bonded joints: contact angles decreased significantly depending on the plasma-parameter setup, surface morphology was also found to vary with plasma power, exposure time and working gas.

Plasma Polymerisation

The aim of this work is to develop hydrophobic coatings on leather materials by plasma polymerisation with a low-pressure plasma system using an organosilicon compound, such as hexamethyldisiloxane (HMDSO), as chemical precursor. The hydrophobic coatings obtained by this plasma process were evaluated with different experimental techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and standardised tests including colour measurements of the samples, surface coating thickness and water contact angle (WCA) measurements. The results obtained indicated that the monomer had polymerised correctly and completely on the leather surface creating an ultra-thin layer based on polysiloxane. The surface modification produced a water repellent effect on the leather that does not alter the visual appearance and haptic properties. Therefore, the application of the plasma deposition process showed promising results that makes it a more sustainable alternative to conventional functional coatings, thus helping to reduce the use of hazardous chemicals in the finishing process of footwear manufacturing.
