Application and characterization of boron-based silane structures on textile surfaces

In this thesis, functional silane analogues were synthesized to develop textile materials with enhanced antipathogenic properties, followed by fabric surface modifications. Antipathogenic surface coatings were developed on different types of fabric using the sol-gel technique. The antipathogenic and antibacterial properties of the modified textile surfaces obtained as a result of these surface coatings were examined. Today, functional textile structures are important for both medical and industry because they have both functionality and high added value. In particular, many textile organizations carry out R&D activities to develop textile products with increased functionality. For this reason, textile surface modifications are important and will contribute to the development of textile materials to be used in the future. In this thesis study, two main stages were presented to obtain functionalized textile surfaces. In the first stage, functional silane analogues were developed and fabric surface modifications were provided to develop textile materials with antibacterial properties. Boron-Based antibacterial surface coatings were developed on different types of fabric using the sol-gel technique. In the second stage, fabric surface modifications were developed with Colemanite and Ulexite Boron minerals using TEOS. The structures obtained in both stages were illuminated with techniques such as fourier transform infrared spectroscopy, SEM and optical microscopy. Additionally, surface coatings, liquid contact angle, fabric mechanical properties and thermal analysis methods were examined. Additionally, the antibacterial activity of the resulting fabrics was determined. Within the scope of the study, by including the silane group on the fabric group with cellulose structure, a peak belonging to the Si-O-Si group was seen in the FTIR spectroscopy at 1000-1100 cm-1. In boron-doped structures, boron-oxygen peaks were seen at 1365 cm-1. A thermal increase of approximately 50 oC was determined in the thermal properties of both boron and silicon coated fabric structures. The mechanical properties of the textile material also increased and antibacterial properties were determined to have improved.
