Abstract

As one of the most prominent anticake agent, SiO2 nanoparticle synthesis method was modified and investigated for a better understanding of the fabrication process. Hence, tetraethoxysilane presursor was subjected to varying synthesis procedures such as concentration change and surface modification ligants. pH value and all the other material composition was kept the same and by implying sol-gel reaction mechanism, basic catalysis and temperature allowed us to obtain spherical and monodispersed nanoparticles. Additionally surface composition which provides hydrophobic character could also be controlled by spontaneous reaction of the long alkyl chain containing alkyltrialkoxysilanes with tetraalkoxysilane. Statistical analysis of the nanoparticle sizes with atomic composition, unveiled that SiO2 nanoparticle size can be modulated sensitively. Monodispersed, spherical and surface controlled nanoparticles seems promising candidated for the applications in sensors, controlled surface coatings and chemical delivery applications.

Özet

Topaklanmayı önleyici ve en çok bilinen yapılardan biri olarak SiO2 nanopartikül sentezi bu çalışmada modifiye bir metot ile araştırılarak, partikülün elde edilme süreci daha derinden incelenmiştir. Bu amaçla tetraetoksisilan başlangıç maddesi farklı sentez parametreleri ile; mesela konsantrasyon ve yüzey modifiye ajanı değiştirilerek kullanılmıştır. pH değerleri ve diğer reaksiyon malzemelerinin değerleri sabit tutularak sol-jel mekanizması ile bazik kataliz metodu, sıcaklık ayarlamaları ile sonuçta küresel, monodisperse partiküller elde edildi. Aynı zamanda hidrofobik bir karakter kazandırmak için uzun alkil zinciri içeren trialkoksisilan ile tetraalkoksisilan spontane (aynı anda) reaksiyonlarla birleştirildi ve yüzey kompozisyon kontrolü böylece sağlandı. İstatistiksel partikül boyut analizi ve atomik içerik analizi ile ortaya çıkmıştır ki SiO2 partiküllerinin boyutu hassas bir şekilde ayarlanabilir. Monodisperse, küresel ve yüzey modifiye SiO2 nanopartiküller sensörler, kontrollü yüzey kaplamaları, kimyasal taşıma gibi alanlarda kullanılabilecek umut verici malzemeler olarak gözükmektedir.
