Biyolojik Kaynaklı Monolitlerin Sentezi ve Karakterizasyonu

Abstract

Colloidal templating is a versatile and practical method to prepare macroporous polymer monoliths with a welldefined two-stage porosity and tuneable morphology. Due to their advantageous morphology colloidal templated monoliths can find application in many areas. In this study, a renewable monomer was used for the development of sustainable macroporous polymer monoliths. Copolymerization of a renewable monomer mixture in a colloidal system was achieved by using a flexible diacrylate crosslinker. For this purpose, d-limonene was copolymerized with ethylene glycol dimetacrylate (EGDMA) in equivalent ratios to investigate the effect of monomer structure on the final material properties. In the end, thermal and morphological properties of the resulting sustainable macroporous polymer monoliths were investigated by Differential Scanning Calorimetry (DSC), Thermal Gravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM), respectively. Additionally, the specific surface area of the obtained monolithic materials was measured through N 2 adsorption/desorption analyses by applying Brunauer-Emmet-Teller (BET) equation to the N 2 isotherms of the samples. It was determined that the presence of d-limonene led to an extraordinary one-hollowed ring morphology due to the porogen effect of this renewable monomer.
