Theoretical Insights into Three Types of Oxidized Starch-Based Adhesives: Chemical Stability, Water Resistance, and Shearing Viscosity from a Molecular Viewpoint

Figure 1

B3LYP/6-31G computational models of the oxidized modified starch molecules. (a) and (b) are the oxidized starch molecules, respectively; (c) and (d) are the oxidized grafted starch molecules, respectively; and (e) is the oxidized grafted cross-linked starch molecule. Additionally, some main Mulliken charges population in the molecules (a), (b), and (c) were indicated by arrow.
