Abstract
In this study, cotton fabrics were coated with TiO2 nanoparticles using 3-mercaptopropyltrimethoxysilane(3-MPTMS), which is highly reactive to cotton fabrics, as a medium, and the characteristics, antimicrobial properties, and photodegradation properties of the fibers were measured. The manufacturing process is as follows. (1) 3-MPTMS was added to isopropanol, and TiO2 colloid was added to the mixture to prepare a solution. (2) Cellulose fibers were immersed in the prepared 3-MPTMS/TiO2 solution, stirred for 90minutes at 45℃ in a constant temperature water bath, and dried there after. In order to identify the morphology of the cellulose fibers coated with TiO2 nanoparticles, the surface was observed with a scanning electron microscope(SEM), and SEM-EDS was measured to identify the adhesion of TiO2 nanoparticles. The SEM images showed TiO2 nanoparticle and 3-MPTMS coated layers on the fibers and it was identified that TiO2 nanoparticles were attached to the cellulose fibers. The antimicrobial activity of 3-MPTMS/TiO2-treated cotton fabrics was measured using a bacterial reduction method. 3-MPTMS/TiO2 cellulose fibers which was irradiated by ultra violet light, showed antimicrobial activity against Escherichia coli (ATCC 43895) and Staphylococcus aureus (ATCCBAA-1707) unlike unirradiated fibers. The cellulose fibers were stained with methylene blue and the photodegradation performance of the stained fabrics was analyzed. The stained fabrics showed high degradation performance with photolytic reactions of TiO2 nanoparticles.
