“…It is indicated that the prepared homopolymer hydrogels with 0% and 100% of KOH resulted in a small amount of crosslinked hydrogel network. As a result, the hydrogel products can only absorb and retain small quantities of water [31].…”

“…The radiation processing has several advantages such as the simultaneous crosslinking and sterilization in one step and the easy control of physical properties of hydrogels by combining dose with polymer composition; it allows fabricating a pure and human-friendly product noncontaminated with ballast materials or the residuals of toxic initiators [30]. Irradiation technique was successfully reported by some researchers to synthesize superabsorbent hydrogels, some were using gamma-irradiation [24], [25], [30], [31], blue and green LED irradiations [32], microwave irradiation [26], and electron beam irradiation [33]. The aim of this research is to synthesize the superabsorbent hydrogel from chitosan and partially neutralized the acrylic acid by using the gamma-irradiation method.…”

Acrylic acid is a hydrophilic monomer which becomes the most popular material used to synthesize superabsorbent polymer. In this recent study, acrylic acid was partially neutralized with KOH and mixed with chitosan to form a superabsorbent hydrogel poly (acrylic acid)-graft-chitosan by using of gamma ray irradiation technique. The aim of this study was to determine the optimum composition of KOH in acrylic acid partial neutralization process for enhancing the production of grafted polymer. The degree of neutralization was varied (0, 25, 50, 75, and 100)% and the effect on the superabsorbent characteristics were studied. Hydrogel products were characterized by Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). The gel content, swelling ratio, Equilibrium Degree of Swelling (EDS), and Thermal Analysis were also performed. The highest water swelling capacity was 715 (g water/g dry hydrogel), and the gel content was 91.23%, resulted from 75% of acrylic acid neutralization. The swelling capacity of the products was also tested in urea and NaCl solutions and reached 750 (g urea solution/g dry hydrogel) for urea and 378,33 (g NaCl solution/g dry hydrogel) for NaCl. The huge water absorption capacity indicated that the hydrogel from this research was a superabsorbent product which was suitable for hygiene products application. The degree of neutralization did not show a significant influence on the thermal resistance of the grafted hydrogel produced in this study.

“…This results in negative charges along the repelling polymer chain, which forces the polymer chain to open and bind water with hydrogen bonds (Kalhapure et al, 2016). There is also an increase in the hydrogel porosity as water diffuses into the hydrogel pores (Erizal et al, 2015).…”

Hydrogels are ideal biomaterials owing to their unique network structure that facilitates considerable hydrophilicity and biocompatibility. At the same time, hydrogels also possess soft physical properties when combined with living tissue. In this study, metformin hydrogen chloride (metformin HCl)-loaded stimuli-responsive poly(N-isopropylacrylamide) (pNIPAAm) -chitosanpolyvinyl alcohol (PVA) hydrogels were synthesized through a freezing and thawing procedure and subsequently subjected to gamma irradiation at room temperature. The gel content and the water absorption capacity of the synthesized hydrogels were analyzed. The polymer interaction in the matrix was observed by Fourier transform infrared spectroscopy, and the release of metformin HCl was studied in different pHs and temperatures. The hydrogels had 85% of the gel content and 373% of the water absorption capacity after 24 h of water immersion. The metformin HCl-loaded (pNIPAAm-chitosan-PVA) hydrogels demonstrated a sustained drug release profile over 7 h. The drug release exhibited pH-dependent and temperature-dependent behavior. The developed hydrogels showed good metformin HCl release ability at pH 3 and pH 6.86 at the temperature of 37 o C. The results showed that pNIPAAm-chitosan-PVA hydrogels could be employed for controlled drug release of metformin HCl.
