“…For example, at the strain of 0.22%, the G ′ of CT hydrogel was 39.7 kPa while the CTH4 sample was 125.1 kPa. This means that the incorporation of HNC into the CT matrix remarkably enhanced the stiffness and load bearing capability of the ultimate hydrogels, which is due to the reinforcement effect and restrictions in the chain mobility …”

“…However, when the amount of HNC was added as 4 wt %, the tensile strength was enhanced up to 0.71 MPa and the elongation at break was reduced to 49.93%. This might be due to the interaction between the hydroxyl groups of CT and HNC seemed to be entrained the rigidity of the structure when the HNC content increased . Thus, the stabilization of the hydrogel composites has been improved at higher nano‐filler loading, resulting in decreased elongation values.…”

Halloysite nanoclay (HNC) was mixed with Chitin hydrogel film by phase inversion in water vapor atmosphere at room temperature. In the preparation, Chitin was dissolved in N,N‐dimethyl acetamine/lithium chloride (DMAc/LiCl) and different amounts of HCN was dispersed well for the gelation process. The resultant Chitin‐Halloysite nanoclay (CTH) hydrogel films containing HCN at 0, 0.1, 0.5, 1, and 4 wt % were used for the adsorbents of heavy metal ions. As the results, the tensile strength of the hydrogel composite was enhanced from 0.34 to 0.71 N/mm2 while the elongation decreased from 66.43% to 49.93% with the increment of HNC concentration from 0 to 4 wt %. A reduction in the water content and the increment in the modulus confirmed the formation of highly dispersed nano‐composites with improved interfacial interactions between nano‐fillers and matrix. In the adsorption experiments of the ternary ion of Pb2+, Cu2+, and Cd2+, the removal capacity of Pb(II) was highly retained by the CTH hydrogel film relative to Cd(II) and Cu(II), shown Langmuir model with the maximum binding amount on the hydrogel composites were followed as order Pb (8.2 mg/g), Cu (4.2 mg/g), and Cd (2.1 mg/g). © 2018 Wiley Periodicals, Inc.

“…The enhanced interfacial cross-linking of PDA in the system might resulted in a compact structure of the hybrid films and a reduction in the polymer chain mobility, thereby prolonging the pathway of gas molecules and limiting the permeation of water vapor molecules under the dense network [65]. In addition, the water vapor permeation occurred in the empty spaces of polymer amorphous regions rather than the crystalline regions, which might also lead to a reduction in the water vapor passages [66]. This conclusion was consistent with the ATR-FTIR and XRD results.…”

The demands for strong integrated biopolymer materials have substantially increased across various industries. In this study, a biomimic strategy was proposed to prepare the poly(dopamine)‐functionalized carbon nanotubes (PDCNTs) via mussel‐inspired chemistry. The graphene dispersion was prepared in aqueous bovine serum albumin solution by ultrasonic treatment through a facile and green approach. Inspired by the excellent integration of mechanical properties and hierarchical nano/microscale structure of natural nacre, we fabricated soy isolate protein (SPI)‐based nanocomposite film with 2D graphene nanosheets and 1D surface‐functionalized PDCNTs through a layer‐by‐layer assembly process. The morphology and thickness of graphene nanosheets were analyzed by atomic force microscopy. The successful surface modification of PDCNTs was confirmed by X‐ray photoelectron spectroscopy and transmission electron microscopy. The cross‐linking hierarchical structure of the SPI hybrid film was observed in scanning electron microscopy images. A combination of multiple interfacial interactions and enhanced adhesion between the PDCNTs‐graphene conjugation and SPI matrix resulted in a remarkable improvement in the mechanical properties of the SPI‐based nanocomposites. When compared with the unmodified film, the tensile strength and elongation at break of the hybrid film were simultaneously increased by 158.93 and 78.67%, respectively. As a result of the enhanced tortuosity effect, the water vapor permeability was significantly reduced by 33.65%. In addition, the resultant film also possessed favorable water resistance, thermal stability, and ultraviolet–visible light barrier behavior. This work provided a novel bio‐inspired interfacial toughening strategy for constructing high performance biopolymer nanocomposites. POLYM.
