“…Fluorine atoms were found to efficiently attach to polymer surfaces by the use of SF 6 plasma treatment (Bastos et al, 2009). The wettability of Thai silk has been improved by SF 6 plasma treatment Suanpoot et al, 2008). Similar processing was effective on a starch surface (Bastos et al, 2009), in which the surface became hydrophobic, and the interface between the starch surface and water droplet was significantly stabilized due to the association of different factors: surface structuring, fluoride incorporation and surface reticulation.…”

The development of thermoplastic materials based on starch has become a promising alternative for reducing plastic waste. To this end, plasma treatments were used to enhance the hydrophobicity of cornstarch films. Cornstarch films plasticized using glycerol and distilled water were prepared by casting. A surface modification method was employed using different precursor gases, HMDSO and SF(6), and a combined treatment using HMDSO followed by SF(6) (HMDSO/SF(6)) and then the reverse, using SF(6) first followed by HMDSO (SF(6)/HMDSO). The results indicated that the induced surface morphology determines the contact angle. It was observed that all films became hydrophobic, and films that were initially treated with SF(6) showed the greatest hydrophobicity if no further coating was applied, or if the treated surface was further coated using HMDSO. Under both of these treatment conditions the contact angle was greater than 110°.

“…RF plasma treatment is a non-hazardous and environmentally friendly technique and has the advantage over wet chemical treatment in terms of reduction in energy consumption, avoidance of solvents and reduced treatment time [210] . Several investigations have been conducted on RF plasma treatment of silk fibers in order to modify wetting, dying and printing properties, tensile properties, shrink resistance, flame retardance, anti-bacterial properties, hydrophilicity and hydrophobicity (Table 3) [211–216] .…”

Biomedical textiles and fiber-based implants (BTFIs) have been in routine clinical use to facilitate healing for nearly five decades. Amongst the variety of biomaterials used, silk-based biomaterials (SBBs) have been widely used clinically viz. sutures for centuries and are being increasingly recognized as a prospective material for biomedical textiles. The ease of processing, controllable degradability, remarkable mechanical properties and biocompatibility have prompted the use of SBBs for various BTFIs for extracorporeal implants, soft tissue repair, healthcare/hygiene products and related needs. The present review focuses on BTFIs from the perspective of types and physical and biological properties, and this discussion is followed with an examination of the advantages and limitations of BTFIs from SBBs. The review covers progress in surface coatings, physical and chemical modifications of SBBs for BTFIs and identifies future needs and opportunities for the further development for BTFIs using SBBs.

“…The powdered forms were pressed into pellets with a hydraulic force of 10 and 7 N, respectively [28]. The pellets were exposed to SF 6 plasma, which was produced by an inductively coupled RF discharge at 13.56 MHz, as described elsewhere [3]. The RF generator, a Dressler model HPG1365, was connected to an antenna through a matching network.…”
