Fifth International Mediterranean Congress on Natural Sciences, Health Sciences and Engineering (MENSEC V) 189 Development of Hydrophobic Surface Properties of Textile Polyesters by Sol-Gel Method Ms. Sule Pinar Cinfer, Yildiz Technical University email@example.com Ms. Rumeysa Kayhan, Yildiz Technical University firstname.lastname@example.org Ms. Ebru Aydin, Yildiz Technical University email@example.com Dr. Afife Binnaz Hazar Yoruc, Yildiz Technical University firstname.lastname@example.org In recent years, the usage areas of hydrophobic polyesters have increased due to their properties such as durability, wettability, breathability and dirt repellency. Generally, it is seen that hydrophobic surfaces are being developed by fluorochemicals, waterrepellent agents, silicone- and paraffin-based water-repellants, aluminum and zirconium compounds. However, as these methods are harmful to human health and the environment, they have started to lose their attractiveness. Research has started to focus on nanoparticles such as silica since it does not show negative effects. According to the literature, nanotechnology and nanomaterials have begun to be of interest as hydrophobicity increases when particle size decreases. Since particle size can be controlled better, the sol-gel method was used in this study. The aim of this study is to increase the hydrophobicity by coating the silica nanoparticles synthesized by the sol-gel process on the polyester surface and observe the effect of parameters such as absorption conditions, temperature, and dispersant. The morphological structure of the silica nanoparticles and polyester fabrics are analyzed by Scanning Electron Microscope (SEM). Wettability of fabrics and chemical structure of the specimens are examined by contact angle analysis and FTIR, respectively. Results approve that the decrease of the particle size increases the hydrophobicity. On the other hand, agglomeration occurs while particle size decreased. Ongoing projects focused on homogeneous coating without agglomeration.
