Abstract

Bu çalışma iki aşamada gerçekleştirilmiştir. İlk aşamada; bir anilin türevi olan 2-okso-2-feniletil-2-aminobenzoat (OPA) bileşiği uygun bileşenlerden başlanarak sentezlenmiştir. Daha sonra OPA’nın başlatıcı olarak amonyum peroksidisülfat (APS) ve çözücü olarak DMF varlığında kimyasal polimerleşmesi sonucu poli (OPA) elde edilmiştir. Poli(OPA)/Bentonit (BNT), BNT’in inorganik tabakalarının poli(OPA) matrisinde interkalasyon yöntemi ile etkin bir şekilde dağıtılmasıyla sentezlenmiştir. İkinci aşamada ise sentezlenen OPA, poli(OPA) ve poli(OPA)/BNT nanokompozitin karakterizasyonu incelenmiştir. OPA, sıvı kromatografi kütle spektrometresi (LC/TOF-MS) kullanılarak karakterize edilmiştir. Poli(OPA) ve poli(OPA)/BNT nanokompozitinin yapıları Fourier Dönüşümlü Kızılötesi Spektroskopisi (FTIR), termal gravimetrik analiz (TGA) ve taramalı elektron mikroskobu (SEM) kullanılarak karakterize edilmiştir. Ayrıca poli(OPA)/BNT nanokompozinin iletkenliği araştırılmış ve elektriksel iletkenliğindeki değişim incelenmiştir.

Synthesis, Characterization and Investigation of Electrical Conductivity of Poly(2-Oxo-2-Phenyl Ethyl -2-Amino Benzoate)/Bentonite Nanocomposite

Abstract

This study was carried out in two stages. In the first stage; 2-oxo-2-phenylethyl-2-aminobenzoate (OPA) compound, which was an aniline derivative, was synthesized by starting the appropriate components. Then, poly(OPA) was obtained via chemical polymerization of the OPA in the presence of ammonium peroxydisulfate (APS) as the initiator and DMF as the solvent. Poly(OPA)/Bentonite (BNT) nanocomposite was synthesized by effectively dispersing the inorganic nanolayers of BNT in poly(OPA) matrix by means of intercalation method. In the second stage; the characterization of the synthesized OPA, poly(OPA) and poly(OPA)/BNT nanocomposite was investigated. The OPA was characterized by liquid chromatography mass spectrometry (LC/TOF-MS). The structures of the poly(OPA) and nanocomposite(OPA) were characterized by using Fourier Transform Infrared Spectroscopy (FTIR), thermal gravimetric analysis (TGA) and scanning electron microscopy (SEM). In addition, the conductivity of poly(OPA)/BNT nanocomposite was investigated and change in electrical conductivity was examined.
