Bu çalışmanın amacı iç içe geçmiş polimer ağ yapılar (Interpenetrating Polymer Network, IPN) sentezleyerek potansiyel bir salım sistemi geliştirmektir. IPN tipi hidrojeller, doğal polimerlerden karboksimetil selüloz ve jelatin kullanılarak, jelatinin çapraz bağlayıcısı olan gluteraldehit varlığında sentezlenmiştir. Sentez sırasında hidrojel karışımına tabakalı yapıdaki Montmorilonit kili eklenmiştir. Elde edilen hidrojeller hidrojel oluşum verimi, şişme/bozunma testleri, Fourier Dönüşümlü Kızılötesi Spektroskopisi (FT-IR), X-Işını Kırınımı (XRD) ve Taramalı Elektron Mikroskobu (SEM) analizleriyle karakterize edilmiştir. Şişme testleri ağ yapıdaki MMT varlığının hidrojelin şişme özelliğini azalttığını göstermiştir. SEM görüntülerinden, yapıya eklenen MMT kilinin polimer ağ içerisinde homojen bir şekilde dağıldığı ve gözenek içlerine yerleştiği gözlenmiştir. Sentezlenen hidrojeller bu özellikleri sayesinde tarım, gıda, boya giderme ve biomedikal uygulamalarda alternatif bir salım sistemi olabilir.
