The method of TiO 2 -anatase film preparation on cotton and viscose fabric surfaces using the sol-gel process and microwave treatment is presented. Microwave treatment was used to change the amorphous TiO 2 form to anatase directly on the fabrics. The influence of microwave treatment conditions on the obtainable polymorphic form of TiO 2 was examined. Fabrics were pretreated with low-temperature air plasma (30 min). The root mean square height in the selected area increased from 44 to 166 nm (cotton) and from 9 to 112 nm (viscose). Infrared analysis showed the new band at 1748 and 1732 cm -1 corresponding to C=O stretching for plasma-treated cotton and viscose textiles, respectively. The plasma pretreatment also improved the wetting properties by TiO 2 sol and increased the surface free energy of fabrics. TiO 2 film thickness was 180 nm (12 %wg. Ti) and 140 nm (3 %wg. Ti) for cotton and viscose, respectively. TiO 2 -modified cotton reduced the nicotine concentration three times more and TiO 2 -modified viscose was two times higher under sunlight compared to raw fabrics. No changes in strength were observed for TiO 2 -modified cotton, while the strength of TiO 2 -modified viscose decreased about 45 %. No effect of UV irradiation on cotton and a slight reduction of the strength of raw viscose (7 %) and TiO 2 -modified viscose (16 %) were observed. The Ti contents after washing decreased from 12 to 11 % (cotton) and from 3 to 2.6 % (viscose). The presented method allows obtaining TiO 2 film-anatase on the cotton and viscose fabrics, but its total effectiveness is better for cotton fabrics.

“…In MNFC/30/, it is possible to identify irregular both small and large voids appearing after plasma treatment, while in MNFC/300/, the surface of the film has almost no such jagged appearance with voids only smaller than 1 lm. Nitrogen plasma treatment, thus, obviously changes the morphology of the films, on both the micro (nano) and macro level, which is likely also to have an influence on the wetting behaviour and decrease in CA due to the increased meniscus liquidsolid wetting line length (Prysiazhnyi et al 2013;Pertile et al 2010).…”

“…Dielectric barrier discharge (DBD) plasma operates in a thermodynamically non-equilibrium condition (so-called cold plasma) in which the ion and molecular translational temperature is much lower than the electron temperature, such that excessive gas heating can be suppressed (Kostic et al 2009;Prysiazhnyi et al 2013). The advantage is that the plasma can be generated at atmospheric pressure, either in open or closed environment.…”

Nitrogen plasma surface treatment for improving polar ink adhesion on micro/nanofibrillated cellulose films

et al. 2019

View full text Add to dashboard Cite

We find that nitrogen plasma treatment of micro/nanofibrillated cellulose films increases wettability of the surface by both liquid polar water and nonpolar hexadecane. The increased wetting effect is more pronounced in the case of polar liquid, favouring the use of plasma treated micro/nanofibrillated cellulose films as substrates for a range of inkjet printing including organic-based polar-solvent inks. The films were formed from aqueous suspensions of progressively enzymatic pretreated wood-free cellulose fibres, resulting in increased removal of amorphous species producing novel nanocellulose surfaces displaying increasing crystallinity. The mechanical properties of each film are shown to be highly dependent on the enzymatic pretreatment time. The change in surface chemistry arising from exposure to nitrogen plasma is revealed using X-ray photoelectron spectroscopy. That both polar and dispersive surface energy components become increased, as measured by contact angle, is also linked to an increase in surface roughness. The change in surface free energy is exemplified to favour the trapping of photovoltaic inks.

Plasma treatment of viscose cellulose fabric was performed using the atmospheric pressure dielectric barrier discharge (DBD) in nitrogen. Samples were treated using nonthermal plasma, and change of sorption properties with plasma energy density was investigated. It was found that using low energy of discharge, modified viscose samples become less hydrophilic and their wettability is significantly reduced. The observed hydrophobic effect was investigated and confirmed throughout series of experiments, by measuring a change in wetting time and in the level of aqueous liquid repellency. Structural changes were monitored using SEM, AFM, and XPS. It was established that increase of roughness combined with removal of hydrophilic polar groups from the surface of cellulose using plasma represents a novel approach to impart hydrophobicity onto hydrophilic textile. An additional binding of copper ions to nitrogen DBD treated cellulose produces a cross‐linking effect, i.e., an occupation of remaining hydrophilic groups on the fabric surface and provides so called “petal effect” where drops of water stick to the fabric surface when the fabric is tilted for 180°. This novel procedure for obtaining hydrophobic cellulose could be used for a preparation of special protective textile materials with cost and time effective methods and chemicals.
