“…No significant changes to bulk material tensile properties were observed in VUV-irradiated (172 nm), γ-irradiated (up to 20 kGy), or C 3 F 6 -plasma-treated degummed silkworm silk fabrics and corona discharge-treated raw silk fabrics, or argon-plasma-treated degummed silk fibers . A decrease in tensile properties was reported with UV-irradiated spider silk fibers and degummed silk fiber, γ-irradiated degummed silkworm fibers , and regenerated silkworm silk films, e-beam-irradiated degummed silk fibers, and air-plasma-treated samples (up to 20 min) . The majority of studies report that tensile breaking strength properties start to decrease at much lower doses when applied to individual fibers or regenerated silk films.…”

“…88 Air plasma treatment of raw silk fibers showed an increase in carbon and a decrease in oxygen content. 89 The highly reactive radical species generated through the cleaving of mainly glycine and alanine amino acid bonds react with atmospheric gases which tend to form volatile products and generate oxygen and nitrogen functional groups on the surface. Post-handling following surface irradiation, such as washing samples in water 88 or placing samples under vacuum, 89 can also result in different surface chemistries.…”

Silk-based materials are widely used in biomaterial and tissue engineering applications due to their cytocompatibility and tunable mechanical and biodegradation properties. Aqueous-based processing techniques have enabled the fabrication of silk into a broad range of material formats, making it a highly versatile material platform across multiple industries. Utilizing the full potential of silk in biomedical applications frequently requires modification of silk's surface properties. Dry surface modification techniques, including irradiation and plasma treatment, offer an alternative to the conventional wet chemistry strategies to modify the physical and chemical properties of silk materials without compromising their bulk properties. While dry surface modification techniques are more prevalent in textiles and sterilization applications, the range of modifications available and resultant changes to silk materials all point to the utility of dry surface modification for the development of new, functional silk biomaterials. Dry surface treatment affects the surface chemistry, secondary structure, molecular weight, topography, surface energy, and mechanical properties of silk materials. This Review describes and critically evaluates the effect of physical dry surface modification techniques, including irradiation and plasma processes, on silk materials and discusses their utility in biomedical applications, including recent examples of modulation of cell/protein interactions on silk biomaterials, in vivo performance of implanted biomaterials, and applications in material biofunctionalization and lithographic surface patterning approaches.

Abstract:A plasma-induced ozone colour-fading treatment was used for treating a blue sulphur-dyed knitted cotton fabric. Since the process parameters of plasma-induced ozone colour-fading treatment are inter-related with one other, the final colour-fading results are affected. An orthogonal array testing strategy (OATS) method was used for determining the optimum conditions of the plasmainduced ozone colour-fading treatment in this study. Three process parameters used in the plasmainduced ozone colour-fading treatment, i.e., oxygen gas concentration (%), water content in fabric (%), and treatment time (minutes), were used in the optimization process. Experimental results reveal the optimum conditions for fading the colour by plasma-induced ozone colour-fading treatment are: (1) oxygen gas concentration = 70%; (2) water content in fabric = 35%; and (3) treatment time = 30 min. The order of importance of these parameters is: oxygen gas concentration > water content in fabric > treatment time. In addition, the plasma-induced ozone colour-fading treatment can effectively remove the colour from the dyed fabric and the colour-fading effect is uniform and even.
