Surface treatment of mulberry silk was carried out using a VUV excimer lamp (172 nm). The changes occurring in morphology and physical properties of silk were studied. The nanopores created on the surface of treated samples were quantitatively analyzed using a high resolution scanning electron microscope. The physical and chemical changes taking place in silk fabric on irradiation were studied through measurement of wetting and wicking time, weight loss, crystallinity, and strength. Effect of irradiation time and distance from the lamp on these properties was also studied. Results show that wettability and wickability of silk improved significantly on exposure before stabilizing at 5 min irradiation time while the weight loss continued to increase. The effect of irradiation was negligible when the distance of the sample from the lamp became >15 mm. The effect of irradiation on tensile strength was found to be insignificant. Presence of moisture in silk hindered the effect of irradiation.

“…The extent of these processes depends on the laser wavelength, frequency, and the intensity used, as well as the target material properties. 11,[25][26][27] When the process is thermally controlled, the absorbed energy increases the density of free electrons and provides them with a substantial amount of kinetic energy, in a very short time. In most cases, the heat energy is sufficient to activate a thin layer of the surface, without melting it.…”

“…Therefore, it is difficult to accurately calculate ⌬H deg resulting from laser irradiation. For example, we can use the failure of COH bonds for illustration, as the breaking energy of COH bond per mole is usually lower than that of many other bonds (i.e., COO, COC), 11 and every material we tested has this bond. In addition, the reaction between COH and O 2 is quite common during laser irradiation of polymers.…”

ABSTRACT:Excimer laser irradiation provides a new and important method for polymer surface treatment. In this work, the weight loss of engineering polymers PC, ABS, PS, and nylon 6 were investigated following irradiation by KrF excimer laser. The experimental results revealed that the polymeric weight loss is nonlinearly related to the laser energy and laser frequency for most of the materials tested. The effects of laser irradiation on the thermal properties (T g or T m ) of the polymers were investigated using DSC. It was found that the T g and T m of these materials decreased as a result of laser treatment, indicating the degradation effect of the laser irradiation procedure.
