Özet:

 With the advantages of their self-healing, stimuli-response ability, water sorption capacity and shape memory, hydrogels have been commonly utilized. However, new strategies have been developed to enhance mechanical and thermal properties of hydrogels in addition to increase their water sorption. In this study, stimuli-responsive acrylamidesodium methacrylate based hydrogels were synthesized with the optimization of sodium methacrylate amount by free radical polymerization. With the incorporation of optimum amount of polyethylene glycol 400 PEG-400 into the hydrogel network, semi-interpenetrating polymer network semi-IPN hydrogels were prepared. With the addition of kaolin, swelling properties of the semi-IPN composite hydrogels were investigated in water under the effect of different pH and temperature. Maximum swelling percent of the semi-IPN composite hydrogels was determined as 24214 at pH 7 and 25 C. Fourier transform infrared spectroscopy FTIR analyses revealed that hydrogel samples were successfully synthesized. Morphological structure of hydrogel samples was examined by scanning electron microscopy SEM analyses. Both of the water motion through the hydrogel layered structure and water diffusion into the pores made the semi-IPN composite hydrogel more swollen material compared to the acrylamidesodium methacrylate based hydrogel.

 Kendi kendini onarma, uyarı-cevap yeteneği, su sorpsiyonu kapasitesi ve şekil hafızası avantajları ile hidrojeller yaygın bir şekilde kullanılmaktadır. Ancak hidrojellerin su sorpsiyonuna ek olarak mekanik ve termal özelliklerini de geliştirmek amacıyla yeni stratejiler geliştirilmiştir. Bu çalışmada sodyum metakrilat miktarının optimizasyonu yapılarak serbest radikal polimerizasyonu ile akrilamitsodyum temelli uyarı-cevap hidrojelleri sentezlenmiştir. Hidrojel ağına optimum miktarda polietilen glikol 400 PEG-400 eklenmesi ile yarı-iç içe geçmiş polimer ağ semi-IPN hidrojelleri hazırlanmıştır. Kaolin ilavesi ile semi-IPN kompozit hidrojellerinin farklı pH ve sıcaklık etkisi altında şişme özellikleri incelenmiştir. Semi-IPN kompozit hidrojelinin pH 7 ve 25 Cde maksimum şişme yüzdesi 24214 olarak belirlenmiştir. Fourier dönüşümlü kızılötesi spektroskopisi FTIR analizleri hidrojel örneklerinin başarılı bir şekilde sentezlendiğini ortaya çıkarmıştır. Hidrojel örneklerinin morfolojik yapısı taramalı elektron mikroskobu SEM analizleri ile incelenmiştir. Hem hidrojelin tabakalı yapısında suyun ilerleyişi hem de suyun gözeneklere difüzyonu, semi-IPN kompozit hidrojelini akrilamitsodyum metakrilat temelli hidrojel ile karşılaştırıldığında daha çok şişen bir malzeme yapmıştır.
