“…Therefore, it can be inferred that the etching process with incoherent UV radiation of excimer lamps is mainly of a photolytic nature. Similar results have been reported by Zhang, Boyd, and Esrom (1996), with a 222 nm excimer lamp.…”

Sericin, a silk protein, has high potential for use in biomedical applications. It has important attributes such as excellent oxygen permeability, cell protecting and antioxidant action, moisture regulating ability, protection from ultraviolet (UV) radiation and microbes, wound healing, anticancer and anticoagulant properties. Sericin, however, has no direct affinity for textiles. In this study conditions for imparting a durable finish to polyester, based on sericin have been optimized. Ten grams per litre of sericin concentration with 10 mL/L of glutaraldehyde cured at 130°C for 2 min was found to give best application. Sericin content in finished samples was estimated by measuring the colour value of treated fabrics dyed with Methylene Blue. SEM analysis showed creation of nano-roughness on the surface of polyester after exposure to UV light and smoothening of fabric surface after application of sericin. Treated samples showed enhanced vertical wicking and moisture regain. They also exhibited improved antistat, ultraviolet protection and radical scavenging activity. These properties make sericin-treated fabrics suitable for use as medical textiles in wound dressings and for healing abrasive skin injuries in patients suffering from atopic dermatitis, pressure ulcers and rashes.

“…The trend is partially caused by both the polydispersed PAA chain length and the agglomeration of the grafted chains to irregular islands on the PET surfaces during the drying process. Moreover, it has been recently shown that the surface roughness of PET surface during UV irradiation is positively correlated with both UV intensity and exposure time [16]. The extensive roughening of PET surfaces at the microscale (on a larger field of view of 15 Â 15 mm) as a result of PAA grafting is further confirmed by scanning electron microscopy (data not shown).…”

“…Therefore, the modification and control of the surface properties of PET is a research topic for materials processing in the last decades. The oxidation and the etching of the PET surface have been attempt by the dry processes such as UV radiation [1][2][3][4][5][6] and plasma exposure [7][8][9][10], which produce no toxic or hazardous liquids from the treatment processes.…”

Surface modification of PET films by atmospheric pressure plasma exposure with three reactive gas sources

et al. 2012

The surface modification of poly (ethylene terephthalate) (PET) film was carried out using an atmospheric pressure plasma (APP) jet device with three reactive gases: air, N 2 , and Ar. The water contact angles on the PET film were found to decrease considerably after the APP exposure. The changes in the advancing and receding contact angles of water on the APP-exposed PET film with aging time were examined by the wetting force measurements employing the Wilhelmy method. The hydrophobic recovery due to the rinsing with water as well as the aging in air was observed only for the advancing angle, which was probably caused by the dissolution of low molecular weight oxidized materials into water, the loss of volatile oxidized species to the atmosphere and the reorientation and the migration of polymer chains. The wettability and the surface free energy of the APP-exposed PET film after diminishing hydrophobic recovery was sufficiently large compared with the untreated film. X-ray photoelectron spectroscopy confirmed that the PET film surface was oxidized due to the APP exposure. When N 2 gas was used for the APP exposure, the surface nitrogen concentration was found to increase with decreasing D. The surface oxygen concentration on the APP-exposed PET film was reduced by rinsing with water, in accordance with the hydrophobic recovery behavior. From atomic force microscopy, surface topographical change due to the APP exposure was observed. The changes in the PET surface properties due to the APP exposure as mentioned above were remarkable for using N 2 gas.
