This work aims to study the rheological behavior of Xanthan-based hydrogels crosslinked using Citric Acid and Borax crosslinking agents at different temperatures to regulate the rheological properties and flowability of Xanthan-based hydrogels at various temperatures. The samples were synthesized via common solution mixing method, followed by heating at desired temperature to ensure the crosslinks formation. Rheological behavior of the samples have been studied in 25 (room temperature), 37 (human body temperature) and 60 (high temperature) degrees Celsius using oscillatory shear rheometer. The results have shown that the storage and loss moduli of the samples were increased with temperature, which has been attributed to conformational reformation of Xanthan chains at higher temperatures. The increase in storage and loss moduli for crosslinked hydrogels was lower, compared to the samples with no crosslinking agents. This behavior was attributed to the suppressed conformational changes of Xanthan chains due to the formation of crosslink bonds. The crosslinking was further approved by FTIR analysis and the results, alongside with the accepted mechanism for crosslinking of Xanthan with Citric Acid, were used to propose a mechanism for the crosslinking of Xanthan in the presence of Borax. Also, the results have shown that the blocking effect of Borax on Xanthan chains conformational change is superior to that of Xanthan – Citric Acid hydrogels, indicating stronger interactions of Borax with functional groups of Xanthan chains.
