%T Understanding the rheology of novel guar-gellan gum composite hydrogels
%X Hydrogels are hydrophilic polymeric materials, prepared from either synthetic or natural macromolecules. However, synthetic hydrogels are now gradually being replaced with natural hydrogels owing to their non-toxicity, biocompatibility and biodegradability. The present work focused on synthesizing novel composite hydrogels of guar gum and gellan. The synthesized guar-gellan composite hydrogels were further characterized rheologically to understand their functional properties. Arrhenius and power law models were fitted for elucidation of their steady flow behavior. Interestingly the guar-gellan composite hydrogels showed remarkable stability and maintained elasticity at high temperatures and angular frequency. The comprehensive analysis of rheological data of novel guar-gellan gum composite hydrogels suggested their potential advantages over gellan gum and its applicability in diverse industrial sectors.
