“…[135] Textiles: Textiles such as cotton already have some surface roughness, so treatments to render them super-hydrophobic can be performed. Treatments of paper [135] and cotton fabric [136,137] have been carried out to make super-hydrophobic materials. Changing the textiles from their natural hydrophilic form to being extremely water repellent means that not only will the fabric be kept dry, but the flexibility and insulating properties can be maintained.…”

The interest in highly water-repellent surfaces has grown in recent years due to the desire for self-cleaning surfaces. A super-hydrophobic surface is one that achieves a water contact angle of 150 degrees or greater. This article explores the different approaches used to construct super-hydrophobic surfaces and identifies the key properties of each surface that contribute to its hydrophobicity. The models used to describe surface interaction with water are considered, with attention directed to the methods of contact angle analysis. A summary describing the different routes to hydrophobicity is also given.

“…In recent years, the influence of low-temperature plasma on paper, textile and biopolymers has been extensively studied. [11][12][13][14][15][16][17][18] Various gases and vapours of liquids can be used as starting plasma for discharging ions, depending on the purposes of the study. 19,20 For cellulose-based materials, if a fluorine-containing compound is used as the treating gas, it is possible to obtain a water-resistant surface owing to the fluoro-functional groups created on the surface that lowers the surface energy.…”

Effects of Treatment Time by Sulfur Hexafluoride (SF₆) Plasma on Barrier and Mechanical Properties of Paperboard

Sulfur hexafluoride (SF6) plasma, using inductively coupled plasma technique, was applied on paperboard surfaces. Effects of different treatment times on water and oil resistances, mechanical properties (through tensile, compression and folding endurance tests) and barrier properties [through water vapor transmission rate (WVTR) and oxygen transmission rate (OTR)] were determined. Results showed that SF6 plasma treatment can improve water resistance properties of paperboard significantly, beginning with only a 2 s treatment time (p ≤ 0.05), whereas oil resistance properties can be improved over a longer time period. Plasma treatment had no effect on tensile strength of treated paperboard; however, machine direction (MD) compression strength, as well as MD and CD folding endurance, of treated paperboard was significantly lower than that for an untreated sample (p ≤ 0.05). WVTR and OTR of treated paperboard were higher with increasing treatment time, because of fluorine atoms and electron bombardment causing etching of cellulose fibres.

“…This method is also time-saving, eco-friendly, effective and economical, and is especially suitable for continuous and large-scale processing of filaments and other textile structural materials [20,21,22]. To the best of our knowledge, the present reported plasma treatment of PI fiber mostly focused on the temperature-resistant properties of ordinary PI fiber or short PI fiber [23,24,25,26,27,28], and the mechanical properties of plasma treatment of high-performance PI filaments have never been reported. The high-performance PI filaments are highly promising for aerospace engineering, electric cables and other applications due to its continuity, ease of handling, and orientation selection during composites fabrication.…”

Abstract:Interface issues urgently need to be addressed in high-performance fiber reinforced composites. In this study, different periods of O 2 plasma treatment are proposed to modify twist-free polyimide (PI) filaments to improve hydrophilicity and mechanical and interfacial properties. Feeding O 2 produces chemically active particles to modify the filament surface via chemical reactions and physical etching. According to the X-ray photoelectron spectroscopy (XPS) results, the PI filaments exhibit an 87.16% increase in O/C atomic ratio and a 135.71% increase in the C-O functional group after 180 s O 2 plasma treatment. The atomic force microscope (AFM) results show that the root mean square roughness (Rq) of the treated PI filaments increases by 105.34%, from 38.41 to 78.87 nm. Owing to the increased surface oxygenic functional groups and roughness after O 2 plasma treatment, the contact angle between treated PI filaments and water reduces drastically from the pristine state of 105.08 • to 56.15 • . The O 2 plasma treated PI filaments also demonstrate better mechanical properties than the pristine PI filaments. Moreover, after O 2 plasma treatment, the adhesion between PI filaments and poly(amic acid) (PAA) is enhanced, and the tensile strength of the polyimide/poly(amic acid) (PI/PAA) self-reinforced composites increases from 136 to 234 MPa, even causing the failure mode of the composite changes from adhesive failure to partly cohesive failure.
