Co2 Laser Radiation

Thermooxidation of LDPE films by CO2 laser radiation, 10.6 μm, was characterized by Fourier transform infrared spectroscopy with attenuated total reflectance (FTIR-ATR). The formation of carbonyl and hydroxyl functional groups onto LDPE films was dependent on the fluency of CO2 laser. IR absorption of vinyl groups and C-O bond present in alcohols showed a decrease and an increase, respectively, indicating that CO2 laser radiation causes simultaneous formation and accumulation of hydroperoxides in LDPE films; furthermore, crystallinity of LDPE films irradiated with CO2 tends to increase. So, CO2 laser radiation is able to oxidize the LDPE films, obtaining a PE with similar spectroscopic properties to that of PE-BIO by a physical process.

Sem Analyses

The aim of this experimental study was to obtain disposable antimicrobial cotton fabrics through applications of tea tree oil/ethyl cellulose (TTO/EC) microcapsules. For this purpose, the TTO/EC microcapsules were prepared and characterized via scanning electron microscopy (SEM) and Fourier transform infrared-attenuated total reflectance (FTIR-ATR) analyses. The characterized microcapsules were then applied to 100% cotton fabric samples via the padding method and were investigated by FTIR-ATR and SEM analyses. In addition, the antibacterial activities of TTO, TTO/EC microcapsules, and fabric samples were also assessed against Escherichia coli and Staphylococcus aureus bacteria. The results showed that the microcapsules were successfully prepared and applied to the fabric samples. In addition, the targeted antimicrobial activities on the textile surfaces were achieved within acceptable levels.
