Abstract:

 


Superabsorbents
hydrogel were prepared by using Zr pillared- montmorillonite KSF by graft
copolymerization reaction of acrylic acid (AA). 
Swelling behavior of pillared clay based superabsorbent films in
distilled water and different pH values were investigated at room temperature.
It was also obtained that pillared clay based superabsorbents were pH dependent
and showed a reversible swelling behavior. Water absorbency of pillared clay
based superabsorbent (PILC-SA) was increased by decreasing pillared clay amount
in the network of the superabsorbents. SEM and XRD analysis were conducted for
further characterization of the PILC-SA. XRD revealed the basal spacing of the
pillared clays before and after in-situ incorporation indicating that the
morphology of the superabsorbent was exfoliated and the layers of clay
dispersed on the composite.

Süperabsorplayıcı hidrojeller Zr sütunlu montmorillonit KSF ile akrilik
asitin (AA) aşı kopolimerizasyon tepkimesi ile hazırlandı. Sütunlu kil tabanlı
superabsorplayıcı filmlerin şişme özellikleri oda sıcaklığında destile edilmiş
suda ve farklı pH değerlerinde araştırıldı. Sütunlu kil tabanlı
süperabsorplayıcıların pH duyarlı ve yenilenebilir şişme özelliği olduğu
bilgisine de ulaşıldı. Sütunlu kil tabanlı süperabsorplayıcıların (PILC-SA) su
absorplaması süperabsorplayıcının yapısındaki sütunlu kilin miktarının
azalmasıyla artmaktadır. SEM ve XRD analizleri PILC-SA’ların
karakterizasyonları için gerçekleştirildi. Sütunlu killerin etkileşime girmeden
önce ve sonraki tabakalar arası mesafesine XRD ile bakılarak
superabsorplayıcıların morfolojisinin değiştiği ve kilin tabakalarının kompozit
üzerinde dağıldığı ortaya çıkarıldı.
