Abstract

In this study, it was aimed that produce new polymeric hydrogels and that investigate the equilibrium swelling properties. Chemically crosslinked copolymeric hydrogels, composed of methacrylamide (MAAm) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) were prepared via free radical copolymerization method. The obtained copolymeric hydrogels were characterized with FT-IR analysis and SEM techniques. In addition, swelling tests 25 oC were applied to all the synthesized samples and swelling characterization studies were performed. The influences of reaction variables such as monomer/co-monomer composition, crosslinker amount on swelling properties of hydrogels were investigated. When the swelling results are evaluated; It was observed that all polymeric samples showed different swelling and diffusion properties depending on their composition.

Metakrilamid Esaslı Polimerik Hidrojellerin Denge Şişme Çalışmaları

Abstract

Bu çalışmada, yeni polimerik hidrojellerin üretilmesi ve denge şişme özelliklerinin araştırılması amaçlanmıştır. Metakrilamid (MAAm) ve 2-akrilamido-2-metil-1-propansülfonik asit (AMPS)’den oluşan kimyasal çapraz bağlı hidrojeller, serbest radikal kopolimerleşme yöntemi ile hazırlanmışlardır. Elde edilen kopolimerik hidrojeller FTIR analizleri ve SEM teknikleri ile değerlendirilmiştir. Ayrıca tüm sentezlenen numunelere 25 oC’de şişme testleri uygulanmış ve şişme karakterizasyon çalışmaları yapılmıştır. Hidrojellerin şişme davranışları üzerine monomer/yardımcı monomer bileşimi ve çapraz bağlayıcı miktarı gibi reaksiyon değişkenlerinin etkileri araştırıldı. Şişme sonuçları değerlendirildiğinde; tüm polimerik örneklerin bileşimlerine bağlı farklı şişme ve difüzyon özellikleri gösterdikleri belirlenmiştir.
