Bioinspired High-Strength Montmorillonite-Alginate Hybrid Film: The Effect of Different Divalent Metal Cation Crosslinking.

ABSTRACT: The natural nacre has a regular ordered layered structure of calcium carbonate tablets and ion crosslinking proteins stacked alternately, showing outstanding mechanical properties. Inspired by nacre, we fabricated different divalent metal cation-crosslinked montmorillonite-alginate hybrid films (MMT-ALG-X²⁺; X²⁺ = Cu²⁺, Cd²⁺, Ba²⁺, Ca²⁺, Ni²⁺, Co²⁺ or Mn²⁺). The effect of ionic crosslinking strength and hydrogen bond interaction on the mechanical properties of the nacre-mimetics was studied. With the cations affinities with ALG being increased (Mn²⁺ < Co²⁺ = Ni²⁺ < Ca²⁺ < Ba²⁺ < Cd²⁺ < Cu²⁺), the tensi
