Okso Metakrilat İçeren Polimer/Kil Nanokompozitlerin Sentezi, Karakterizasyonu ve Termal Özellikleri

Bu çalışmada, polimer/kil bazlı nanokompozitlerin sentezi ve karakterizasyonu, 2-(4-metoksifenil amino)-2-oksoetil metakrilat (MPAEMA) ve organokil kullanılarak gerçekleştirilmiştir. İn situ (yerinde) polimerizasyon yöntemi ile sentezlenen nanokompozitlerde organokil miktarı %3 ve %5 olarak belirlenmiştir. Karakterizasyon teknikleri olarak FTIR, XRD ve SEM kullanılmıştır. Nanokompozitlerin morfolojisinin eksfoliye yapıda olduğu XRD ve SEM sonuçlarından belirlenmiştir. Daha sonra, nanokompozitlerin termal özellikleri TGA/DTA/DTG eşzamanlı sistem kullanılarak incelenmiştir. Termal analizde kil miktarı arttıkça ısıl kararlılığın arttığı görülmüştür. Doğal kil içerikli bu yeni sentezlenen sentetik polimer/kil nanokompozitlerin çevre dostu, biyolojik olarak parçalanabilir özelliklerinden dolayı farklı alanlara hizmet edeceği düşünülmektedir

Synthesis, Characterization and Thermal Properties of Oxo Methacrylate-Containing Polymer/Clay Nanocomposites

In this study, synthesis and characterization of polymer/clay based nanocomposites was performed using 2-(4-methoxyphenylamino)-2-oxoethyl methacrylate (MPAEMA) and organoclay. The amount of organoclay in nanocomposites synthesized by in situpolymerization method was determined as 3% and 5%. FTIR, XRD, and SEM were used as characterization techniques. It wasdetermined from XRD and SEM results that the morphology of nanocomposites exfoliated. Then, the thermal properties ofnanocomposites were investigated using the TGA/DTA/DTG simultaneous system. In thermal analysis, it was seen that the thermalstability increased when the clay amount increased. It is thought that this newly synthesized synthetic polymer/clay nanocompositeswith natural clay content will serve different areas due to its environmentally friendly-biodegradable properties.
