Abstract

Sodium Alginate and Gelatin blends showed strong response towards the external stimuli of pH and ionic strengths. Molecular dynamics simulations were used to study the hydrogen bonding interactions in these blends when subjected to different pH and different ionic strength medium. The effect of plasticizers viz. glycerol and polyethylene glycols of different molecular weights on the blend were also studied. In addition, the effect of external stimuli and plasticizers upon the individual constituents of the blend viz. Sodium Alginate and Gelatin were also studied in order to understand their combined effect in the properties shown by the Sodium Alginate and Gelatin blend. Polyelectrolytic properties of sodium alginate and polyampholytic properties of gelatin were explored both in presence and absence of salt. Finally, the simulation results for gelatin in salt medium were verified using theoretical expressions and experimental analysis of the same system.
