| Abstract: |
| Silicon dioxide nanoparticles are the basis for a great deal of research due to safety, low toxicity, capability to be functionalized with a range of compounds and also stability against chemical, biological, physical and thermal conditions. Also, SiO2 nanoparticles can be create multifunction properties such as high thermal resistance and hydrophobic or hydrophilic characteristics on textiles. In this research, silica nanoparticles were in-situ synthesized on polyethylene terephthalate (PET) fabric at room temperature and characterized with diverse instruments. Sodium silicate was used as a precursor in acidic and alkali media for in-situ synthesis of silica nanoparticles on polyester. The optimum processing conditions was obtained based on the highest hydrophilic or hydrophobic properties. The silica nanoparticles formed in the remaining solution were also characterized by scanning electron microscopy (SEM) and XRD. Interestingly, some fabrics showed hydrophilic and others indicated hydrophobic properties depending on the synthesis conditions and type of the materials used. Those fabrics prepared in acidic media indicated hydrophobic effects as longer time need for the water to spread on the fabric surface while those samples produced in alkali media showed hydrophilic properties as the water spread on the fabric surface in a shorter time. |
