“…This migration is difficult when, during the treatment, cross links are formed between the polymeric chains, resulting that the treated polymer may return to its hydrophobic original characteristic after same elapsed time [17][18][19][20][21][22] .…”

Polyester fabric samples -PET (poly (ethylene terephtalate)), were treated with oxygen plasma, in order to alter the hydrophilicity of such material. The process parameters: working pressure, current, tension and temperature were kept constant, varying only the treatment time. In order to evaluate the change caused on samples hydrophilicity, as well as the influence of the treatment time, the vertical wicking test was used. The samples were stored at standard temperature and pressure conditions, and their wettability were measured one day after the treatment and repeated after 30, 60 and 360 days, in order to check the stability of the effects produced. Scanning electron microscopy (SEM), Raman and ATR (Attenuated total reflection) spectroscopies were used to evaluate physical and chemical alterations on the samples surface. The results have shown a substantial improvement on the hydrophilicity of the treated samples compared to the non-treated sample.

“…[38,39] This phenomenon was attributed to chain motion on substrate surface. [40] In our method, the coating showed a good stability, and after half-year storage the coated surface still maintains superhydrophobicity. We found that this method can considerably enhance the formation of SiOSi bonds within the silane coating layer.…”

A novel method to prepare durable superhydrophobic fabrics through pre‐applying an alkyl silane (alkyl chain longer than C15) onto fabric substrate and by subsequent vacuum plasma treatment in argon is reported. The treated fabrics show a contact angle of 154.2° with low contact angle hysteresis (sliding angle 4.5°). The coatings are durable and can withstand 150 cycles of standard laundries. The argon plasma treatment is found to significantly enhance SiOSi bonding among the silane molecules, leading to a highly crosslinked silica network. The silane coating also shows high optical transparency. Apart from fabrics, other substrates such as filter paper, plastic film, glass slide, silicon wafer, and metal are treated in a similar way, and all the treated surface show durable hydrophobicity, though the contact angle is lower than that of the coated fabrics. Post‐crosslinking of silane through argon plasma treatment may offer a facile but environment‐friendly way to prepare durable superhydrophobic fabrics.

“…Any change in surface free energy can be easily detected by a change in the contact angle of water with the surface of the modified polymer. 18,19 Plasma polymerization of monomer vapors on polymer substrates have been also used for the modification of properties of substrate polymers. 20 Plasma polymerization of TEOS was carried out on PE substrate with a special aim to improve barrier properties.…”

In the present study plasma polymerization of tetraethylorthosilicate and hexamethyldisiloxane was carried out on polyethylene film with an aim of enhancing barrier properties. The glow discharge was obtained at 0.2 mbar using 13.56 MHz radio frequency source capable of giving power out put up to 100 W. The monomer vapors were passed in the system at the rate of 15 SCCM. The extent of deposition was determined from the weight gain study and the morphology was studied using SEM. Films were further characterized by surface energy measurement, ATR-FTIR and ESCA analysis. Since PE is widely used for packaging and in this process a thin layer of glass-like transparent SiOx was deposited, therefore it was thought necessary to study permeability to water vapors.
