FTIR spectra of (A) before and (B) after the addition of glutaraldehyde into P:P and P:P:Bs solutions. Reduction of peak intensity observed related to –OH groups. New peaks were observed related to (-COO-M+) groups. An increase in peak intensity was observed related to C–O–C groups. (C, D) Schematic representation of the dual cross-linking process of PGS by the modified BGs and glutaraldehyde. (E) Variation of viscosity of P:P and P:P:Bs solutions before (I) and after (II) addition of glutaraldehyde. (F) Comparison of viscosity of P:P and P:P:Bs solutions after addition of glutaraldehyde. (G, H) Comparison of viscosity of P:P and P:P:B1 solutions, respectively, before and after the addition of glutaraldehyde.
