Synthesis and characterization of poly(o-toluidine)/kaolinite conductive composites for humidity and temperature sensing
Öz: Conductive poly(o-toluidine)/kaolinite composite was synthesized viachemical polymerization of o-toluidine in the availability of kaoliniteusing ammonium persulfate as oxidizing agent. To investigate the useof the prepared conductive composite as humidity and temperaturesensor, the effect of polymerization conditions such as HCl, o-toluidineand oxidant concentrations on the amount of conductive POT containedin the composite and the conductivity values of composites wereinvestigated. It was found that the composites with the highest poly (o-toluidine) content (29.4%) and conductivity (8.3×10-4 Scm -1 ) wereobtained by 0.2 M ammonium persulfate, 0.4 M o-toluidine and 1 Mhydrochloric acid for 2 hours of continuous polymerization at 20 °C. Theresistivityvaluesofpurepoly(o-toluidine)andpoly(o-toluidine)/kaolinite composite were monitored during heating-cooling cycles in the range of 0-100 °C. Changes in resistivity for purepoly(o-toluidine) and poly(o-toluidine)/kaolinite composite withhumidity 30-90% were examined and humidity sensor behavior wasdetermined. Characterization of the prepared composite was performedby Fourier transform ınfrared spectroscopy (FT-IR), X-ray diffraction(XRD), thermogravimetric analysis (TGA) and scanning electronmicroscopy techniques (SEM).

Öz: İletken poli(o-toluidin)/kaolinit kompoziti, kaolinit varlığında yükseltgen olarak amonyum persülfat kullanılarak o-toluidinin kimyasal polimerizasyonu ile hazırlandı. Hazırlanan iletken kompozitin nem ve sıcaklık algılayıcısı olarak kullanımını araştırabilmek için kompozitin içerdiği iletken POT miktarı ve kompozitin iletkenlik değerlerine polimerizasyon koşullarından HCl, o-toluidin ve yükseltgen madde derişimlerinin etkisi incelendi. En yüksek poli(o-toluidin) miktarı (%29.4) ve iletkenliğe sahip (8.3×10 -4 Scm -1 ) kompozitin 0.2 M amonyum persülfat, 0.4 M o-toluidin ve 1.0 M hidroklorik asit kullanılarak 20 °C sıcaklıkta ve 2 sa. sürdürülen polimerizasyon ile elde edildiği bulundu. Saf poli(o-toluidin) ve poli(o-toluidin)/kaolinit kompozitinin direnç değerleri 0-100 °C sıcaklık aralığında tekrar edilen ısıtma-soğutma işlemleri sırasında izlenerek sıcaklığa karşı duyarlılığı incelendi. Bağıl nem oranı %30-90 arasında değiştirilen ortamlarda saf poli(o-toluidin) ve kompozitin direnç değerleri ölçülerek nem sensör davranışı belirlendi. Hazırlanan kompozitin karakterizasyonu Fourier dönüşümlü kızılötesi spektroskopisi (FT-IR), X-Işınları kırınımı (XRD), termogravimetrik analiz (TGA) ve taramalı elektron mikroskobu (SEM) teknikleri ile yapıldı.
