Abstract

Silica is one of the most attractive nanoparticles because it has many advantages such as non-toxic, biocompatible, relatively inexpensive, high thermal resistance, and especially being able to strengthen the mechanical properties of polymer matrices. Due to these properties, it has been frequently used in surface modification studies recently. In generally, chemical methods are used for surface modification of inorganic particles such as silica. However, there is a possibility that these methods may contain chemical contamination. Therefore, it is aimed to develop a reliable alternative process for surface modification by using enzymes. For this purpose, surface modification of silica was performed by binding of methacrylic acid (MAA) with enzyme catalyzed reaction to silica surface. Modified silica particles have been characterized by Fourier Transform Infrared Spectrophotometer (FTIR), Scanning Electron Microscope (SEM) and Thermogravimetric Analysis (TGA).
