Calcium phosphate (CaP) filled bacterial cellulose (BC) and polyvinylpyrrolidone (PVP) based hydrogel scaffolds (BC-PVP-CaP) are being reported here considering its possible application in bone restoration. The primary focus of this work is to analyze the viscoelastic behavior of ‘BC-PVP-CaP’ hydrogel scaffolds at human fever temperature condition (39 degree C) in swelled state. In BC-PVP scaffolds, CaP is present in the form of β-tricalcium phosphate (β-TCP) and hydroxyapatite (HA) in different concentrations (i.e. β-TCP/HA_20:80, β-TCP/HA_40:60, β-TCP/HA_50:50). During evaluation of viscoelasticity, BC-PVP scaffold (without CaP) was marked as a control set. The BC-PVP-CaP_50:50 hydrogel scaffold showed the highest degree of swelling at 39 degree C among the other BC-PVP-CaP scaffolds. Regardless of it, the other hydrogel scaffolds were also showed notable viscoelasticity at 39 degree C. Experimental results confirmed that all the CaP filled BC-PVP hydrogel scaffolds (BC-PVP-CaP_20:80, BC-PVP-CaP_40:60, BC-PVP-CaP_50:50) exhibit a promising swelling and viscoelastic behavior at human fever temperature condition (39 degree C), can be endorsed for its potential application in bone repairing /bone restoration.
